A medical practice reviews its monthly accounts receivable report and discovers $180,000 in outstanding balances older than 90 days.
The billing team knows the money is unpaid, but the report does not explain what needs to happen next.
Some claims are still waiting for payer processing. Others were denied, underpaid, or never properly followed up. A few may already have been paid but are still showing as outstanding because payment posting was incomplete.
Working every account in the same way would waste time and could leave important reimbursement opportunities unresolved.
The most effective approach to medical accounts receivable over 90 days is to organize outstanding claims by payer, identify their actual payment status, and assign a specific recovery action to each account.
A payer-specific recovery worklist turns an aging report into a practical follow-up system.
Instead of asking employees to call insurance companies about every old balance, it shows which claims need status verification, which require appeals, which have payment discrepancies, and which need additional investigation.
This guide explains how to organize the 90+ day backlog, separate the balances correctly, and prepare the information needed to build a reliable payer-specific recovery worklist.
What Does Medical Accounts Receivable Over 90 Days Mean?
Medical accounts receivable over 90 days refers to outstanding healthcare billing balances that have remained unpaid for more than 90 days, based on the aging method used in the report.
For physician practices, standard revenue cycle reporting commonly measures A/R aging from the date of service.
For example, a claim for a service provided 105 days ago may appear in the 91–120 day aging category if an outstanding billed balance remains on the account.
However, the claim may have been submitted much later than the service date because of documentation delays or another billing issue.
This is why practices should understand how their billing system calculates age.
The Healthcare Financial Management Association (HFMA) MAP Keys defines standard billed A/R aging categories for physician and ambulatory services using the date of service.
These categories include 0–30, 31–60, 61–90, 91–120, and over 120 days.
For this guide, 90+ day A/R means balances in the 91–120 and over-120-day categories.
Does an Account Over 90 Days Mean the Claim Was Denied?
No.
An unpaid claim may be older than 90 days without having received a formal denial.
For example, an insurance company may still be processing an accepted claim. The billing team may be waiting for requested documentation, or a payment may have been issued but not posted correctly.
Other accounts may have received a denial that requires reconsideration or appeal.
The appropriate recovery action depends on the claim’s actual processing history.
This distinction matters because submitting a corrected claim when the payer has already issued payment will not resolve a posting problem.
Likewise, repeatedly checking the status of a denied claim does not address the denial itself.
Are Claims Older Than 120 Days Still Recoverable?
Yes, some claims older than 120 days remain recoverable.
The age of a claim does not automatically determine whether reimbursement is available.
Recoverability depends on the original submission, payer processing history, coverage, documentation, contractual requirements, and any remaining correction or appeal opportunities.
For example, a claim older than 120 days may still be awaiting a valid appeal decision.
Another claim of the same age may have already been processed correctly and require a contractual adjustment rather than additional collection efforts.
Older claims should be investigated, not automatically classified as lost revenue.
Pro Medical Billing Solutions (PROMBS) supports healthcare practices through medical accounts receivable over 90 days recovery workflows, including payer follow-up, denial investigation, payment posting reviews, and outstanding balance management.
Our approach focuses on identifying what is preventing payment before deciding how an account should be resolved.
Why Medical Claims Remain Unpaid After 90 Days
Medical claims can remain outstanding for several reasons, and identifying the cause is essential before creating a recovery plan.
A practice may have a large 90+ day balance because of delayed claim submission, unresolved denials, payment posting problems, or payer-specific processing delays.
However, the same aging report may contain all of these issues together.
Claims Were Accepted but Not Fully Resolved
An insurance company may accept a claim for adjudication without issuing a final payment decision immediately.
For example, the payer may request additional information or place the claim under review.
If the billing team does not monitor the account, the balance may remain outstanding for several months.
The appropriate next step is to verify the current claim status and determine whether the payer needs anything else.
The CMS Claim Status Request and Response guidance explains that providers can use electronic 276 claim status requests and 277 responses to obtain Medicare claim processing information.
These transactions can reduce the need for manual status inquiries when supported by the billing system.
However, status information alone does not establish whether the remaining balance is collectible.
The team must review the actual claim history and payer response.
Denials Were Not Resolved Promptly
Some aging claims received denials but did not receive the appropriate follow-up.
For example, a claim may have been denied because of a medical necessity determination, an authorization mismatch, or a coding issue.
If the denial requires a formal appeal, repeatedly submitting the same claim may not resolve the problem.
The billing team should verify the payer’s explanation, review supporting documentation, and determine which recovery process remains available.
Applicable appeal deadlines should be checked immediately rather than assuming that the claim’s aging category determines the remaining time to respond.
PROMBS provides denial management services that support claim investigation, appropriate corrections, appeals, and payer communication.
These activities help practices distinguish actionable denials from balances that do not require further recovery efforts.
Payments Were Received but Not Reconciled
An account may appear outstanding because the payment or adjustment information has not been correctly posted.
For example, an insurer may issue payment, but the electronic remittance advice does not reach the expected billing workflow.
Alternatively, a payment may have been posted to an incorrect account.
Before contacting the payer about an apparently unpaid claim, the billing team should review available payment records, electronic remittances, and posted transactions.
Accurate reconciliation can prevent unnecessary collection activity and misleading A/R reports.
Payer Processing or Contractual Issues Remain Unresolved
Some balances remain unpaid because of payer-specific processing problems or potential underpayments.
For example, a commercial insurer may reimburse less than the amount expected under the applicable provider contract.
The billing team should verify the payment against the relevant contractual terms and remittance information.
If an underpayment is confirmed, the next action may involve requesting a payment review or using the payer’s applicable dispute process.
However, the original billed charge should not automatically be treated as the amount the practice is entitled to collect.
The focus should remain on legitimate expected reimbursement.
What Is a Payer-Specific A/R Recovery Worklist?
A payer-specific A/R recovery worklist is an organized queue of outstanding claims grouped by insurance payer and assigned a clear next action.
Unlike a traditional aging report, the worklist explains what billing employees need to do to move each account toward resolution.
For example, a standard report may show that a medical practice has $35,000 outstanding from one insurer in the 91–120 day category.
That information helps management understand the age and size of the balance.
However, it does not explain whether the claims are pending, denied, underpaid, or already paid but not reconciled.
A payer-specific worklist adds this operational information.
How It Differs From a Traditional Aging Report
An aging report answers: How much remains outstanding, and how old is it?
A recovery worklist answers: Why does this balance remain unresolved, who is responsible, and what needs to happen next?
Consider two claims that are both 110 days old.
The first belongs to a Medicare Advantage plan and was denied because the billed service appears inconsistent with the authorization.
The second belongs to a commercial payer and has been processed with a possible contractual underpayment.
Both claims appear in the same aging category.
However, the first requires authorization and denial investigation. The second requires reviewing the remittance and applicable payment terms.
Placing them in one undifferentiated follow-up queue could lead to unnecessary calls and repeated work.
A payer-specific worklist separates these claims according to the procedures needed for resolution.
Why Payer-Specific Organization Matters
Insurance payers do not all use identical claim processing rules.
Original Medicare, Medicare Advantage, Medicaid, and commercial health plans may have different requirements for claim status inquiries, corrections, appeals, and payment disputes.
Even two plans administered by the same insurance company may have different procedures.
Organizing claims by payer helps billing teams identify the appropriate administrative process and recognize recurring patterns.
For example, if multiple unpaid claims from one insurer involve the same payment discrepancy, management may need a payer-level investigation rather than several disconnected claim inquiries.
This is where payer-specific A/R recovery becomes more useful than simply sorting claims from oldest to newest.
How to Separate 90+ Day A/R Before Starting Recovery
Before building the detailed worklist, the practice should separate its aging balances into categories that reflect how the accounts must be handled.
This initial organization helps prevent patient balances, insurance claims, and unresolved financial adjustments from being treated as the same type of receivable.
Separate Insurance A/R From Patient A/R
Insurance A/R represents amounts expected from insurers, while patient A/R reflects balances assigned to patients under the applicable coverage and billing arrangements.
These categories need different follow-up processes.
For example, an outstanding insurance balance may require claim status verification or payer escalation.
A legitimate patient balance may require reviewing the patient’s statement, insurance adjudication, payment history, or an available payment arrangement.
Before transferring a balance to patient responsibility, the billing team should confirm that the payer has processed the claim appropriately and that the amount is valid under the coverage terms and applicable rules.
Practices should also investigate credits and adjustments that may be distorting their reports.
Separating these categories creates a more accurate view of the insurance backlog.
Divide the Backlog Into 91–120 and Over 120 Days
Not every claim older than 90 days requires the same review.
The 91–120 day category may include relatively recent payment delays, while the over-120-day category may contain more complicated unresolved accounts.
However, an older balance is not automatically less recoverable.
For example, a claim in the 91–120 day bucket may already have missed a particular payer deadline, while a 150-day-old claim may remain within a valid appeal process.
The billing team should use aging categories to organize the backlog, then review actual claim status and deadlines to determine the next action.
For broader guidance on deciding which claims should receive attention first, see PROMBS’s article on medical A/R prioritization.
This article focuses on building and operating the payer-specific worklist rather than repeating that broader prioritization method.
Group Claims by Payer, Plan and Provider
After separating insurance and patient balances, organize the insurance A/R by payer.
For example, a medical practice may create separate queues for Original Medicare, individual Medicare Advantage plans, Medicaid programs, and commercial insurers.
Within each queue, the team can further distinguish providers, service locations, and claim categories where useful.
This is especially important for multi-provider practices.
One physician may have repeated enrollment-related problems with a payer, while another has unresolved authorization denials under the same insurance plan.
Without provider-level information, these patterns may be difficult to identify.
PROMBS’s revenue cycle management services support reporting by payer and provider, denial monitoring, and A/R follow-up to help practices understand where outstanding reimbursement is concentrated.
What Information Should You Collect Before Building the Worklist?
A payer-specific recovery worklist is only as reliable as the information used to create it.
If claim status, payment history, or outstanding balances are inaccurate, billing employees may spend time pursuing accounts that have already been resolved.
Before assigning recovery actions, collect the records needed to verify each claim.
Essential Information for Every 90+ Day Claim
The worklist should include:
- Payer and plan: The insurance company and specific coverage product.
- Claim identifier: Internal claim number and payer claim control number, where available.
- Provider and location: Rendering provider, billing entity, and relevant service location.
- Date of service and claim age: Enough information to confirm the aging category.
- Current financial balance: Outstanding amount after recorded payments and adjustments.
- Expected collectible amount: The reimbursement still potentially due after applicable contractual and coverage considerations.
- Claim status: Pending, denied, underpaid, returned, appealed, or another verified status.
- Denial or adjustment information: Relevant CARCs, RARCs, and payer explanations.
- Previous follow-up: Last contact, submission, appeal, or investigation result.
- Applicable deadline: Any verified filing, correction, reconsideration, or appeal deadline.
- Assigned owner: Employee or team responsible for resolution.
- Next action and follow-up date: A specific task and the date it should be reviewed.
This information allows employees to understand the account without repeatedly reconstructing its history.
For example, the note “Claim pending” does not explain why an account has remained unpaid for 115 days.
A more useful record would state that the payer requested medical records, the documents were submitted on a particular date, and the next action is to verify receipt and review the processing status.
The worklist should be maintained in an appropriately secured billing system or authorized work environment, with access limited according to staff responsibilities.
Reconcile Balances Before Assigning Recovery Work
Aging reports can contain errors caused by incomplete payment posting, incorrect adjustments, or duplicate transactions.
Before assigning an account for collection, the billing team should verify that the reported balance remains valid.
For example, if a payer issued a payment last week but the amount has not been posted, the account may still appear in the recovery queue.
The appropriate action may be payment reconciliation rather than another payer inquiry.
Similarly, an account containing an unresolved credit or incorrect contractual adjustment may require a financial review before further collection activity.
PROMBS supports payment posting, remittance reconciliation, and underpayment investigation through its medical billing services.
These activities help practices ensure that A/R recovery efforts focus on accurate and potentially collectible balances.
How to Measure A/R Over 90 Days by Payer
Practice owners need to understand not only how many old claims remain outstanding, but also which payers account for the largest proportion of their aging receivables.
This is where standardized A/R metrics become useful.
The HFMA MAP Keys includes:
AR-1: Aged A/R as a percentage of total billed A/R.
AR-2: Aged A/R as a percentage of billed A/R by payer group.
For physician practices, these measures use the date of service to determine the aging category.
They focus on active billed debit balances and exclude unbilled accounts under the specified definitions.
Calculate the Percentage of A/R Older Than 90 Days
To evaluate the proportion of a payer’s billed A/R that is more than 90 days old, add the balances in the 91–120 and over-120-day categories.
Then divide that total by the billed A/R for the same payer group.
Formula:
90+ Day A/R Percentage = (91–120 Day Billed A/R + Over-120-Day Billed A/R) ÷ Total Billed A/R × 100
The numerator and denominator must use consistent account populations and payer classifications.
For example, consider the following illustrative report.
| Payer group | Total billed A/R | A/R over 90 days | Percentage over 90 days |
|---|---|---|---|
| Commercial Payer Group A | $80,000 | $30,000 | 37.5% |
| Medicare Advantage Group | $100,000 | $10,000 | 10% |
| Medicaid Group | $60,000 | $12,000 | 20% |
Illustrative figures only, not industry benchmarks or actual PROMBS performance data.
Commercial Payer Group A has a substantially higher share of billed receivables older than 90 days than the other groups.
This tells the practice where further investigation may be useful.
However, it does not establish that all $30,000 is recoverable or that the payer is necessarily responsible for the delays.
The billing team still needs to review claim submission dates, processing history, contractual adjustments, and available recovery actions.
For internal operational tracking, practices can build more detailed reports by individual insurance plan, provider, or location while maintaining consistent definitions.
Why the Percentage Matters More Than the Balance Alone
A medical practice may have a large old A/R balance with one insurer simply because that payer accounts for a substantial portion of its patient volume.
Another payer may represent a much smaller total balance but have an unusually high percentage of accounts older than 90 days.
Reviewing both the dollar amounts and the aging percentages helps management understand where the backlog is concentrated.
Practices should also monitor whether those percentages increase or decrease over several reporting periods.
A single monthly figure can identify an area for investigation, but a consistent trend provides more useful information about the effectiveness of recovery efforts.
A/R aging tells you where money remains outstanding. A payer-specific recovery worklist tells your billing team what to do about it.
Turning the 90+ Day Backlog Into an Actionable Recovery Queue
Once the practice has verified its aging balances, separated insurance from patient responsibility, and grouped claims by payer, it has the foundation for a structured recovery process.
The next step is to convert each account into a defined action.
A Medicare claim awaiting a status update should not follow the same workflow as a commercial claim with a medical necessity denial.
Likewise, a possible contractual underpayment should not be handled as though the payer has never processed the claim.
Each account needs a verified status, an appropriate resolution pathway, a responsible employee, and a documented follow-up date.
Through its A/R follow-up, denial management, payment posting, and billing reporting services, PROMBS helps healthcare providers investigate outstanding balances and maintain more organized recovery workflows.
The goal is not to chase every old claim repeatedly. It is to identify legitimate reimbursement opportunities and take the action most likely to resolve each account.
How to Build a Medical A/R Over 90 Days Recovery Worklist
To build a medical A/R recovery worklist, start with a reconciled aging report, identify the current status of every unpaid insurance claim, verify the expected reimbursement, and assign a specific next action based on the payer’s requirements.
A traditional aging report shows which balances have remained unpaid. A recovery worklist explains what the billing team should do about those balances.
This distinction becomes important when a practice has hundreds of claims in the 91–120 and over-120-day aging categories.
For example, a medical practice may have $95,000 in insurance A/R older than 90 days.
Some accounts may require claim status verification. Others may involve authorization denials, contractual underpayments, or unresolved payment posting issues.
Working every account through the same follow-up process can waste staff time and leave legitimate reimbursement opportunities unresolved.
The following five-step process helps practices turn their aging balances into organized, payer-specific recovery queues.
Step 1: Export and Reconcile the Aging Report
Begin by exporting the most recent insurance A/R aging report from the practice management or medical billing system.
The report should identify outstanding balances in the 91–120 and over-120-day categories, using a consistent aging method.
For physician practices, the HFMA MAP Keys uses the date of service for billed A/R aging.
Before assigning follow-up work, verify that the exported balances represent actual open receivables.
For example, an account may appear unpaid because the insurer’s payment was received but not posted correctly.
Another account may contain an unapplied credit or an incorrect contractual adjustment.
If the billing team begins contacting payers without reconciling these records, employees may spend time pursuing balances that do not require additional payment.
The initial review should therefore compare the aging report with available payment records, electronic remittance advice, adjustments, and previous account activity.
Once the balances are verified, remove resolved transactions from the active insurance recovery queue through the appropriate accounting process.
Do not delete claim histories or make unsupported financial adjustments simply to reduce the reported A/R balance.
PROMBS supports healthcare practices through medical billing services that include payment posting, electronic remittance reconciliation, and insurance A/R follow-up.
These activities help billing teams begin recovery efforts with more reliable financial information.
Step 2: Identify Payer, Claim Status and Denial Details
After verifying the outstanding balance, determine where each claim stands in the payer’s processing workflow.
This step is essential because an account that has been denied requires a different resolution from one still awaiting adjudication.
For each claim, verify whether it is:
- Accepted and awaiting payer processing.
- Rejected before adjudication.
- Denied after adjudication.
- Pending additional documentation or review.
- Partially paid with a remaining balance.
- Under reconsideration or appeal.
- Paid but awaiting reconciliation.
These statuses should be based on available claim records rather than assumptions.
For example, a claim may show “Submitted” in the billing software even though the clearinghouse received a rejection from the payer.
The billing team should review the available acknowledgments and payer responses to determine whether the claim actually entered adjudication.
For Original Medicare, the CMS Claim Status Request and Response guidance explains how electronic 276 transactions can be used to request claim status and 277 transactions can return processing information.
Medicare Administrative Contractors also provide other authorized inquiry methods, including provider portals.
When a claim has been adjudicated, review the applicable remittance information.
The CMS remittance advice guidance explains how Claim Adjustment Reason Codes (CARCs), Remittance Advice Remark Codes (RARCs), and adjustment group codes describe payment decisions.
These details help the billing team determine whether the account requires a correction, appeal, payment review, or another action.
Step 3: Verify Expected Reimbursement and Payment History
The outstanding billed balance is not always the amount the practice should expect to collect.
For example, a medical practice may submit a claim with a charge of $2,000.
Under the applicable payer contract, the expected allowed amount may be $1,200.
If the insurer has already paid $900, the remaining collectible amount depends on the remittance details, patient responsibility, and applicable contractual terms.
It would be incorrect to automatically treat the entire $1,100 difference between the billed charge and payment as an insurance underpayment.
The billing team should determine whether the balance represents legitimate payer responsibility, patient responsibility, an appropriate contractual adjustment, or an unresolved posting issue.
This distinction is particularly important when investigating older commercial insurance claims.
A claim may appear partially unpaid because the billing system has not applied the correct contractual adjustment.
Alternatively, the insurer may genuinely have reimbursed less than the applicable agreement requires.
The recovery worklist should record the estimated collectible payer balance only after reviewing the available evidence.
When the expected reimbursement remains uncertain, mark the account for contractual or payment review rather than reporting the entire balance as recoverable revenue.
Step 4: Add Filing, Correction and Appeal Deadlines
Every 90+ day insurance recovery worklist should include applicable deadlines.
However, claim age and filing deadlines measure different things.
A claim may be 130 days old and still have a valid appeal opportunity.
Another claim may be only 95 days old but have an important payer-specific correction or dispute deadline approaching.
The billing team should review three separate timeframes when relevant:
Original claim filing deadline: The date by which the initial claim must reach the correct payer.
Corrected claim deadline: The period available to submit an eligible replacement or corrected claim under the payer’s requirements.
Appeal or dispute deadline: The date by which an eligible party must challenge a payer’s determination or request a permitted payment review.
For Original Medicare, initial claims generally must be submitted within one calendar year after the date of service, subject to limited exceptions.
However, CMS redetermination guidance separately provides a general 120-day period from receipt of the initial determination for requesting a first-level appeal.
These are different requirements.
Medicare Advantage, Medicaid, and commercial plans may use different procedures and deadlines.
The worklist should record the verified deadline, its source, and the responsible employee.
If a deadline appears to have expired, the account should receive an appropriate specialist review to determine whether any valid recovery option remains.
It should not automatically be written off or treated as collectible.
Step 5: Assign the Next Action, Owner and Follow-Up Date
Once the claim’s status and available recovery options are understood, assign a specific action.
This is the point where an aging report becomes an operational worklist.
For example, an account marked “Insurance follow-up” provides limited direction.
A more useful entry would state:
“Verify payer receipt of the medical records submitted on October 20 and review the updated claim status on October 27.”
The worklist should identify the employee responsible for completing that action.
It should also record the next review date, the expected result, and the criteria for escalation.
If the payer requests additional information, the assigned employee should know which department must provide it.
If the account has already been escalated, the follow-up record should identify the escalation reference and next expected response.
A well-maintained medical accounts receivable over 90 days worklist helps practices move beyond repeated status calls and toward documented claim resolution.
How to Organize Separate Work Queues for Different Payers
One of the most important features of a payer-specific worklist is that it recognizes differences between insurance programs.
Original Medicare, Medicare Advantage, Medicaid, and commercial insurance products do not always follow the same claim correction or appeal procedures.
Applying one standard recovery process to every payer can create unnecessary delays.
A billing manager should therefore organize claims into payer-specific queues and provide employees with the appropriate status inquiry, correction, dispute, and escalation instructions.
Original Medicare Claim Status and Appeals
For Original Medicare claims older than 90 days, begin by identifying the Medicare Administrative Contractor (MAC) responsible for processing the claim.
Then verify whether the claim was accepted, adjudicated, denied, or remains under review.
If the claim is still pending, use the contractor’s available status inquiry tools to investigate its processing history.
For example, a claim may have been accepted for adjudication but require additional documentation before a determination can be made.
In that situation, the billing team should review whether the contractor issued an Additional Documentation Request (ADR) and whether the requested records were submitted.
If Medicare has already denied the claim, the next step depends on the reason.
Minor clerical errors in a previously processed claim may qualify for reopening under applicable Medicare rules.
A disputed coverage or payment determination may require a formal redetermination.
The worklist should clearly distinguish these situations.
For example:
Status: Medicare claim denied for medical necessity.
Next action: Review the applicable coverage criteria and supporting clinical documentation, confirm appeal rights, and prepare the appropriate redetermination if justified.
The billing team should not submit an identical claim repeatedly when the actual issue requires formal review.
Medicare Advantage Authorization and Payment Issues
Medicare Advantage claims may require a different recovery approach because they are administered by private health plans under the Medicare Advantage program.
For example, a claim may be denied because the procedure performed does not appear to match the authorization recorded by the plan.
The billing team should compare the approval with the final clinical documentation and submitted claim.
Important details may include CPT codes, rendering provider, service location, dates, and authorized units.
If the original claim contains a genuine error, the plan’s correction procedure may apply.
However, if the claim was submitted accurately and the practice disputes the denial, a plan-specific appeal or other appropriate review process may be necessary.
The recovery worklist should identify whether the issue involves an enrollee coverage determination, a provider payment dispute, or another category with different procedures.
Medicare Advantage appeal rights and provider contractual disputes should not be treated as identical.
The CMS Medicare Advantage reconsideration guidance describes reconsideration rights involving adverse organization determinations.
For billing teams, the correct route must be established using the actual plan, determination notice, and the party’s applicable rights.
PROMBS provides denial management services that support denial investigation, authorization review, payer communication, and appropriate appeal coordination.
Medicaid and State-Specific Claim Requirements
Medicaid claims require particular attention because programs operate under federal and state requirements.
A medical practice may submit some Medicaid claims through a state fee-for-service system and others through a Medicaid managed care organization.
These arrangements may have different claim submission, correction, and appeal procedures.
For example, a claim may remain outstanding because of a coordination-of-benefits issue involving another primary insurer.
The billing team should verify whether the primary payer processed the claim and whether the required payment information reached Medicaid.
In other cases, a claim may encounter a provider enrollment or managed care billing issue.
Before submitting corrections, staff should identify the specific state program or managed care plan and review its applicable instructions.
According to Medicaid.gov’s financial management guidance, Medicaid payment arrangements include state fee-for-service and managed care models.
The recovery team should not assume that one state’s filing or appeal limits apply to another state.
A payer-specific worklist should therefore include the applicable state or managed care plan, relevant billing requirements, and the verified next action.
Commercial Payer Denials and Contractual Underpayments
Commercial insurance worklists often include a combination of denied claims, unresolved payment disputes, and possible underpayments.
For example, an insurer may pay a claim but apply a reimbursement amount that appears inconsistent with the provider’s contracted fee schedule.
The billing team should verify the claim information, contracted terms, allowed amount, remittance adjustments, and provider participation status.
If the payment appears incorrect, the next action may involve a payment reconsideration or contractual dispute.
However, different commercial payers may require different submission channels, documentation, and deadlines.
Some offer separate administrative reconsideration and formal appeal procedures.
Others have distinct processes for corrected claims, coding disputes, and underpayments.
For example, Aetna’s provider dispute guidance distinguishes reconsideration from appeals.
The worklist should identify the actual process applicable to the claim rather than assuming every unpaid balance requires an appeal.
For practices managing several commercial insurers, grouping similar payment discrepancies can also reveal payer-level problems that may justify a broader investigation.
Practical Example: Working Three Unpaid Claims Over 90 Days
To understand how a payer-specific worklist operates, consider a medical practice with several unresolved insurance claims.
The following figures and situations are illustrative. They do not represent actual PROMBS client accounts or guaranteed reimbursement.
Sample 90+ Day Payer Recovery Worklist
| Payer and claim | Age | Potential payer balance | Verified issue | Next action, owner and review date |
|---|---|---|---|---|
| Original Medicare, Claim A | 108 days | $1,180 | Accepted claim awaiting adjudication | Verify status through the MAC; A/R specialist, Oct. 26 |
| Medicare Advantage, Claim B | 132 days | $2,050 | Authorization-related denial | Review approval, clinical records and dispute deadline; denial specialist, Oct. 26 |
| Medicaid, Claim C | 145 days | $540 | Secondary claim missing primary adjudication details | Verify COB records and state or plan submission requirements; secondary billing specialist, Oct. 27 |
| Commercial Payer, Claim D | 158 days | $320 | Suspected contractual underpayment | Compare contract and ERA, then determine dispute action; payment analyst, Oct. 27 |
The balances and internal review dates are examples. External payer filing and appeal deadlines must be verified separately and retained in the complete worklist.
These accounts are all more than 90 days old, but each requires a different action.
Claim A: Medicare Claim Awaiting Processing
Claim A has been outstanding for 108 days.
The billing system shows that the claim was submitted, but there is no final remittance indicating a payment or denial.
The A/R specialist should first confirm that the claim was accepted for adjudication.
Next, the specialist should retrieve the current status through an available Medicare inquiry method.
If the contractor indicates that the claim requires documentation, the team should determine whether the request was received and what remains outstanding.
If the claim is processing normally, the next follow-up should be based on the contractor’s response and any applicable processing requirements.
Submitting another original claim without confirming the current status could create unnecessary duplicate processing.
The worklist should retain the findings and updated next action.
Claim B: Medicare Advantage Authorization Denial
Claim B has an expected collectible balance of $2,050 and has been outstanding for 132 days.
The plan denied payment because the authorization information did not appear to match the billed procedure.
The denial specialist should review the original approval, treatment documentation, final codes, and payer explanation.
Suppose the review confirms that the final claim accurately reflects the service and that the plan may have applied the authorization incorrectly.
The specialist should determine whether an appropriate dispute or appeal remains available and gather the necessary supporting evidence.
If the plan requires a specific appeal process, the worklist should record the verified deadline and submission method.
The billing team should not change an accurately documented procedure code merely to match an approval that may be outdated or incorrectly interpreted.
Claim C: Medicaid Secondary Claim
Claim C has been outstanding for 145 days.
The billing team discovers that the payer needs information about the primary insurer’s processing.
The appropriate next step is to verify the primary claim’s adjudication and ensure that the secondary claim follows the relevant coordination-of-benefits requirements.
The specialist should also confirm whether the claim was submitted to the correct Medicaid program or managed care plan.
If additional remittance information is required, the team should obtain and submit it through the appropriate process.
The account should remain assigned to the secondary billing queue until its status is resolved.
Claim D: Commercial Insurance Underpayment
Claim D has been outstanding for 158 days.
The insurer processed the claim, but the payment appears to be lower than the amount allowed under the applicable contract.
For example, the claim’s expected allowed amount may be $960, with $640 paid and an additional $320 potentially due after accounting for all valid adjustments and patient responsibility.
The billing specialist should verify the contractual fee schedule and remittance information before concluding that the insurer underpaid.
If the $320 difference is supported, the practice can investigate the payer’s applicable payment review procedure.
If the difference is explained by a valid contractual adjustment or another legitimate payment factor, the account should be reconciled rather than disputed unnecessarily.
The lesson from these examples is that claim age identifies the backlog, but verified payer status determines the recovery action.
How to Document Payer Responses and Escalate Unresolved Claims
A payer-specific worklist becomes less effective when employees do not record what happened during follow-up.
For example, a billing specialist may contact an insurer and learn that a claim is awaiting medical records.
If the note simply states “Called insurance,” the next employee may have to repeat the inquiry.
Good follow-up documentation should allow another team member to understand the account and continue the work without reconstructing its history.
Record the Outcome of Every Meaningful Follow-Up
Each payer interaction should include the date, contact method, current claim status, relevant reference number, and specific information received.
When available and appropriate, staff can also record the payer representative’s name or department.
Most importantly, the note should explain what will happen next.
For example:
Weak follow-up note: “Claim pending. Called payer.”
Useful follow-up note: “Payer confirmed records received October 20. Claim remains under medical review. Reference number recorded in billing system. Review updated status October 27.”
The second note provides a clear history and next action.
Records should be maintained securely within the practice’s authorized billing environment.
Establish Escalation Rules
Not every unresolved claim needs immediate supervisor involvement.
However, escalation should occur when routine follow-up is no longer producing meaningful progress.
Examples include repeated contradictory payer responses, unresolved payment discrepancies, missing information about an appeal, or an approaching external deadline.
For instance, if a commercial insurer repeatedly states that a claim will be reprocessed but provides no documented resolution, the billing manager may need to request escalation through the payer’s established provider support process.
The escalation should identify the original claim, the previous actions taken, the outstanding issue, and the specific outcome requested.
Payer reference numbers and prior correspondence can help prevent the team from restarting the investigation.
Avoid Repeated Follow-Up Without a Defined Purpose
A common A/R management problem is contacting a payer several times without identifying what action is needed.
For example, an account may receive repeated notes stating that the claim is still pending.
If the payer has already requested documentation, another general status call may be less useful than confirming that the appropriate records have been delivered.
Likewise, if a claim is under appeal, the team should monitor the correct appeal process instead of attempting unnecessary replacement submissions.
An organized recovery worklist should tell employees whether the next action is to verify status, provide information, correct a claim, pursue a dispute, or reconcile a payment.
PROMBS supports this structured follow-up through its revenue cycle management services, including claim tracking, payer communication, denial management, and aging A/R reporting.
When Should a Claim Be Corrected, Appealed or Reviewed for Adjustment?
The final decision for an aging claim should be based on the actual reason it remains unpaid.
A billing manager should not assume that all claims over 90 days require resubmission or appeal.
Different situations require different resolutions.
Submit a Correction When the Original Claim Contains an Error
A corrected or replacement claim may be appropriate when the original claim contains inaccurate information and the payer permits the change.
For example, a valid coding correction may be necessary when the documented service was reported incorrectly.
The billing team should verify the supporting medical record and follow the payer’s correction requirements.
For Original Medicare, certain minor clerical errors are generally addressed through reopening procedures rather than ordinary commercial replacement-claim methods.
Appeal When the Practice Disputes a Payer Determination
An appeal may be appropriate when the claim was submitted accurately, but the practice has a valid basis to challenge the payer’s decision.
For example, a medical necessity denial may require clinical evidence demonstrating that the service met applicable coverage criteria.
The relevant deadline should be confirmed before preparing the appeal.
A claim already older than 90 days may still have an available appeal opportunity, but that opportunity depends on the determination date and applicable rules.
Review Adjustments When Payment Has Already Been Made
Some accounts remain in the A/R report even though the payer has already processed payment.
These claims may need adjustment verification or payment reconciliation rather than additional collection activity.
For example, a claim could have an outstanding balance because the correct contractual allowance was never posted.
The billing team should verify the remittance before deciding whether the remaining amount represents legitimate payer responsibility.
Similarly, a possible underpayment should be reviewed against the applicable contract before starting a payment dispute.
Seek Specialist Review When Recovery Rights Are Unclear
When a claim appears to have passed its appeal deadline or contains conflicting payer information, the account should receive a more detailed review.
The specialist should verify the determination date, applicable payer rules, prior submissions, and whether another valid recovery pathway remains available.
If the review concludes that the remaining balance is not collectible, any adjustment or write-off should follow the practice’s documented authorization and accounting procedures.
Older claims should not be written off simply because collection appears difficult.
For a deeper explanation of how to choose the appropriate resolution, see PROMBS’s guide on corrected medical claims vs. appeals.
How to Keep a Payer-Specific Recovery Worklist Organized
Building a worklist is only the beginning.
A medical practice needs a process for keeping claim statuses accurate as employees receive payer responses, submit documentation, complete appeals, and reconcile payments.
Each account should have one clearly identified current status and a responsible owner.
When the payer issues a final determination, the billing team should update the account promptly.
When a claim is resolved through payment or an authorized adjustment, it should leave the active recovery queue through the appropriate accounting process.
Claims requiring additional investigation should remain visible rather than being moved into an undefined pending category.
Review Payer-Level Patterns
As the worklist develops, recurring problems may become easier to recognize.
For example, several commercial claims may be delayed because a payer is repeatedly requesting the same documentation.
Another insurer may have recurring payment discrepancies involving one provider contract.
Grouping these issues can help management determine whether individual follow-up is sufficient or whether a payer-level escalation is warranted.
Maintain Separate Records for Actual Collections
The billing team should distinguish claims that were successfully resolved from claims that produced actual additional reimbursement.
For example, a payer may agree to reprocess an underpaid claim, but the practice should not record the disputed amount as recovered revenue until the corresponding payment has been received and reconciled.
This distinction helps prevent inflated recovery reports.
PROMBS supports healthcare providers through payer-specific A/R follow-up, payment posting, denial investigation, and billing analytics.
These activities help practices maintain more accurate recovery queues while identifying the processes responsible for aging balances.
The goal of managing medical accounts receivable over 90 days is not simply to complete more insurance follow-up calls. It is to turn each outstanding account into a documented, appropriate recovery action with a measurable financial outcome.
How to Manage a Weekly 90+ Day A/R Recovery Worklist
Building a payer-specific recovery worklist is only the beginning. The real improvement comes from using it consistently to resolve unpaid claims and prevent accounts from remaining in follow-up queues without meaningful progress.
A medical practice may have hundreds of insurance claims older than 90 days, but simply contacting more insurance companies does not guarantee better collections.
An effective weekly A/R recovery process should verify outstanding balances, complete scheduled follow-up actions, escalate unresolved claims, and confirm the financial outcome of every resolved account.
The billing team should know which claims require attention, what action is expected, and when the next review should occur.
Start Each Week With an Updated Aging Report
At the beginning of each reporting week, refresh the insurance A/R aging report and reconcile it with the active recovery worklist.
Some claims may have received payments since the previous review. Others may have been adjusted, denied, or moved into a different status.
The worklist should reflect those changes.
For example, a claim that received full contractual reimbursement should no longer appear as an unpaid insurance account merely because the payment has not been reflected in the follow-up queue.
Similarly, a claim that received a new denial should be moved to the appropriate resolution workflow.
The team should also identify claims newly entering the 91–120-day category.
This helps management understand whether the backlog is shrinking or whether additional claims continue aging into it.
Work Claims According to Their Next Required Action
Once the records are updated, employees should work the accounts assigned to them.
Rather than reviewing every claim from the beginning, staff should use the documented next action.
For example, one employee may need to verify whether Medicare received requested documentation.
Another may need to submit an appropriate appeal for a Medicare Advantage denial.
A payment posting specialist may need to investigate why a commercial payer’s remittance does not match the account balance.
Each task requires different information and may have a different deadline.
This approach reduces repeated status inquiries and helps staff focus on actions that can move the account toward resolution.
Claims approaching verified filing or appeal deadlines should receive attention promptly, even when their next routine follow-up date is later.
End the Week With a Resolution and Exception Review
Before closing the weekly reporting period, the billing manager should examine which accounts progressed and which remain unresolved.
A claim should not be marked as financially recovered merely because the payer agreed to reprocess it.
The payment must be received and reconciled before the recovered amount is counted as collected revenue.
Similarly, moving an account from one employee’s queue to another does not represent a successful resolution.
The review should confirm whether an account was paid, appropriately adjusted, formally disputed, or assigned a new action supported by the payer’s response.
Any claim without a clear owner or next step should be addressed before the worklist is carried into the following week.
A well-maintained medical accounts receivable over 90 days recovery process makes unresolved accounts visible rather than allowing them to remain indefinitely in general follow-up queues.
Which KPIs Show Whether Aging A/R Recovery Is Working?
A medical practice cannot evaluate A/R recovery using the total outstanding balance alone.
The reported backlog may decrease because insurance payments were collected, but it may also decrease because claims were written off or balances were reclassified.
Likewise, the total may remain unchanged even when employees successfully collect older claims because additional receivables have aged into the same category.
The most useful A/R recovery metrics distinguish aging balances, actual collections, claim resolution activity, and new accounts entering the 90+ day backlog.
Key Metrics for a Payer-Specific Recovery Dashboard
| KPI | What it reveals |
|---|---|
| A/R over 90 days by payer | How much billed A/R remains in the 91–120 and over-120-day categories |
| Percentage of billed A/R over 90 days | How concentrated older receivables are within each payer group |
| Payments collected on 90+ day claims | Actual reimbursement received and posted on identified aging accounts |
| New claims entering 90+ days | Whether additional receivables continue moving into the older aging categories |
| Resolution time | How long identified recovery issues take to reach a documented outcome |
| Unresolved deadline exceptions | Claims requiring urgent action because of a verified filing, correction, or appeal deadline |
These measurements should use consistent definitions and reporting periods.
The HFMA MAP Keys defines aged A/R as a percentage of billed A/R and a corresponding measurement by payer group.
For physician and ambulatory services, billed A/R is generally aged from the date of service under these definitions.
Practices should distinguish these standardized billed A/R measurements from a separate operational report containing only balances being pursued from insurance payers.
The two reports may serve different purposes and should not automatically be presented as interchangeable.
Understand Why a Lower A/R Balance Does Not Always Mean Better Recovery
Consider a medical practice with $100,000 in insurance A/R older than 90 days at the beginning of the month.
During the month, the following activity occurs:
- $25,000 in additional receivables moves into the 90+ day categories.
- $22,000 is collected and posted on older accounts.
- $8,000 is removed through verified adjustments or authorized write-offs.
Assuming no other movements or reclassifications, the ending balance is $95,000.
The practice’s older A/R decreased by $5,000.
However, the actual payments collected were $22,000, while another $8,000 was removed without necessarily producing new cash.
These figures are illustrative.
This example demonstrates why the billing manager should track the movement of balances instead of reporting only the difference between the opening and closing A/R totals.
Authorized contractual adjustments and approved write-offs should be documented separately from recovered insurance payments.
Compare Payer Performance Over Multiple Reporting Periods
A payer may have a high percentage of receivables older than 90 days because of a temporary processing issue.
Another payer may have a consistently smaller aging balance but a recurring pattern of disputed payments.
Reviewing multiple periods helps distinguish temporary fluctuations from persistent operational problems.
For example, if the same commercial insurer repeatedly accounts for a large portion of older receivables, management should investigate whether the issue involves claim submission errors, payment policies, unresolved appeals, or another cause.
PROMBS supports practices through revenue cycle management services that include payer reporting, A/R monitoring, payment posting, and denial trend analysis.
These activities help practice owners understand whether their outstanding balances are being resolved through actual reimbursement or other accounting outcomes.
How to Identify Repeated Payer Delays and Escalation Patterns
Payer-specific worklists can reveal problems that are difficult to recognize when every unpaid claim is treated separately.
For example, a medical practice may notice that several claims from the same insurer remain unpaid after the payer requested additional documentation.
The claims involve different patients, but the payer has provided similar responses during multiple follow-up attempts.
Rather than continuing identical inquiries on each claim, the billing manager should determine whether the accounts share an underlying issue.
Separate Practice-Side Delays From Payer-Side Problems
An unpaid claim does not automatically indicate that the insurer is responsible for the delay.
The practice may have submitted an incomplete claim, failed to provide requested records, or used an incorrect billing configuration.
Before escalating a payer issue, review the relevant claim histories.
For example, if ten claims are pending because the medical practice has not responded to documentation requests, the immediate solution is to address the missing information.
However, if the requested information was properly submitted and the payer repeatedly provides inconsistent processing responses, additional payer investigation may be warranted.
The worklist should distinguish these situations rather than assigning every outstanding balance to a general category such as “insurance delay.”
Recognize Patterns Across Claims
Recurring problems may involve the same payer, plan, CPT code, rendering provider, or denial reason.
For example, a practice may identify repeated underpayments involving a specific service covered under a commercial payer contract.
The billing manager should compare the original claims, remittance information, applicable fee schedule, and previous dispute outcomes.
If the evidence supports a common payment issue, the practice may be able to organize a more effective payer-level investigation.
However, each claim still needs to be reviewed for its individual facts and applicable requirements.
A payer-level pattern should not be assumed merely because several claims have similar outstanding balances.
Escalate With Complete Documentation
A useful escalation should explain what the practice is asking the payer to resolve.
For example, the billing manager may submit a request explaining that several correctly processed claims appear to have been reimbursed below the applicable contract terms.
The request should identify the affected claim references, relevant payment differences, previous inquiries, and supporting evidence.
If the payer’s procedures require individual reconsiderations or appeals, the practice must follow those requirements while coordinating the broader issue.
For Original Medicare claims, the CMS electronic 276/277 claim status process can help providers retrieve status information without repeated manual inquiries, where supported.
Commercial and managed care payers may offer different inquiry and escalation channels.
Effective payer escalation should be based on a documented problem and a requested resolution, not simply the number of times an employee has contacted the insurer.
How to Prevent New Claims From Entering the 90+ Day Bucket
Recovering old claims is important, but practices should also investigate why new receivables continue aging beyond 90 days.
A recovery team may collect substantial amounts from older accounts while newly submitted claims develop the same problems.
Without preventive improvements, the backlog can remain consistently high.
Reduce Charge Entry and Claim Submission Delays
A claim may become old before the insurer has had sufficient time to process it.
For example, a service performed 90 days ago may not have been submitted until several weeks after treatment because of incomplete documentation or delayed charge entry.
If the practice measures aging from the date of service, that claim may enter an older aging category relatively soon after submission.
The billing team should monitor completed encounters that have not reached charge entry, claims held because of missing information, and delays between service delivery and submission.
PROMBS supports medical billing services that include charge entry, claim processing, and submission monitoring.
Addressing these delays helps practices prevent avoidable aging before payer adjudication even begins.
Resolve Claim Rejections Promptly
A claim rejected by a clearinghouse or payer before adjudication should not remain unattended.
For example, a claim may be rejected because of an incorrect subscriber identification number or provider enrollment information.
If the billing team assumes the claim is processing normally, the error may remain unnoticed.
Reviewing acknowledgments and correcting supported submission errors promptly can prevent unnecessary aging.
Practices should also investigate recurring rejections to determine whether the registration or billing system configuration needs improvement.
Investigate Denials Before They Become Older A/R
Some claims are denied early but remain unresolved because the billing team does not determine the correct recovery pathway.
For example, a medical necessity denial may require a formal appeal supported by clinical documentation.
Repeatedly checking the payer’s status without addressing the denial will not resolve the underlying problem.
The team should review denial reasons, preserve applicable deadlines, and identify the appropriate next action soon after the determination.
Early investigation is especially important when documentation must be obtained from the treating clinician.
Improve Authorization and Coding Handoffs
Revenue cycle problems can also originate before claim submission.
A procedure may change after authorization approval, but the updated treatment information may not reach the authorization department.
Similarly, a coding team may receive incomplete clinical documentation and place the encounter on hold.
These communication gaps can delay claims or contribute to preventable denials.
Our related guide on revenue cycle workflow errors explains how scheduling, authorization, and coding handoffs affect reimbursement.
Preventing these problems can reduce the number of unresolved claims entering the aging worklist.
However, not every claim older than 90 days is preventable. Some accounts involve legitimate payer reviews, complex coverage determinations, or disputes that require additional time.
The objective is to reduce avoidable delays while keeping valid outstanding claims under active management.
What Should a Payer-Specific A/R Recovery Audit Include?
A payer-specific A/R recovery audit helps medical practices determine whether older balances are accurate, being worked appropriately, and supported by legitimate reimbursement opportunities.
Unlike a routine aging report, the audit examines individual claim histories and the follow-up processes used to manage them.
An effective A/R recovery audit should verify outstanding balances, evaluate claim status and deadlines, identify recurring payer issues, and confirm whether reported recoveries represent actual collections.
Verify the Accuracy of Aging Balances
Start with a representative sample of claims in the 91–120 and over-120-day categories.
Compare the reported balances with the original charges, remittances, posted payments, adjustments, and current account information.
Look for payments that have not been reconciled, incorrect contractual allowances, duplicate balances, and unresolved credits.
If the report contains inaccurate balances, the recovery worklist may direct employees toward accounts that do not require further payer payment.
Corrections should follow the practice’s established accounting controls and preserve appropriate transaction histories.
Review Recovery Actions and Payer Responses
For each sampled claim, determine whether the billing team selected an appropriate resolution.
For example, a claim with a valid appeal opportunity should not remain assigned to routine status follow-up while the appeal deadline approaches.
A claim already paid should not be repeatedly pursued as unpaid.
A possible commercial payer underpayment should be evaluated against the relevant contract rather than automatically classified as a denial.
The audit should also examine whether employees recorded meaningful follow-up information and maintained clear ownership of unresolved accounts.
Identify Claims With No Clear Next Action
An old claim may receive several payer calls without making progress toward resolution.
For example, a billing employee may repeatedly document that the claim is pending without investigating whether the insurer needs additional information.
The audit should identify accounts where follow-up activity has occurred but no specific action is moving the claim forward.
These accounts may require escalation, documentation review, payment reconciliation, or another specialist investigation.
Review Write-Offs and Financial Outcomes
Aging A/R recovery reports should not treat every adjustment as successful collection activity.
The audit should determine whether accounts were resolved through insurance payments, patient payments, appropriate contractual adjustments, or authorized write-offs.
Potential underpayments should be supported by the applicable reimbursement terms.
If an account is determined to be uncollectible, the decision should follow the practice’s documented review and approval procedures.
Claims should not be written off simply because they have reached the over-120-day category.
PROMBS provides medical billing and coding audit services that help healthcare practices investigate outstanding balances, denial patterns, billing inaccuracies, and revenue cycle weaknesses.
These reviews can help practices distinguish genuine recovery opportunities from reporting or accounting issues.
How Pro Medical Billing Solutions Helps Recover Aging Medical A/R
Medical practices often struggle with older accounts receivable because claims require different types of investigation, and billing employees may not have enough time to work every unresolved account thoroughly.
A claim may need a status inquiry, while another requires a payer appeal, payment review, or correction supported by documentation.
For multi-provider practices, these problems become more complicated when outstanding balances are spread across multiple insurance plans and specialties.
Pro Medical Billing Solutions (PROMBS) provides medical billing, denial management, and accounts receivable services for healthcare practices across the United States.
Our approach focuses on identifying why reimbursement remains outstanding and determining which action is appropriate for the payer and claim.
Payer-Specific Insurance A/R Follow-Up
PROMBS supports healthcare practices by reviewing outstanding insurance balances and organizing follow-up based on payer requirements and claim status.
Our A/R specialists investigate pending claims, review payer responses, and help identify accounts requiring additional action.
For example, a claim awaiting adjudication may need status verification, while a denied claim may require supporting documentation or a formal dispute.
By distinguishing these situations, practices can reduce unnecessary rework and establish clearer recovery responsibilities.
Our medical accounts receivable over 90 days support is designed to help practices examine older balances, identify legitimate reimbursement opportunities, and maintain structured insurance follow-up.
Denial Investigation and Appeal Support
Some aging accounts remain unpaid because an original claim denial was never appropriately resolved.
PROMBS assists healthcare practices with denial investigation, coding and documentation review, appropriate claim corrections, and appeals.
Our team also examines recurring denial patterns that may involve eligibility verification, authorization requirements, or billing accuracy.
The objective is to identify the actual reason for nonpayment rather than repeatedly submitting claims without addressing the underlying issue.
For cases requiring clinical justification, the treating provider remains responsible for supplying the appropriate documentation.
Underpayment Review and Payment Reconciliation
Not every old receivable involves an unpaid claim.
Some balances remain unresolved because the payer issued partial payment, the expected contractual reimbursement requires review, or the remittance was not properly posted.
PROMBS supports payment posting, electronic remittance reconciliation, and underpayment investigation.
Our billing specialists help practices distinguish valid payer balances from patient responsibility, contractual adjustments, and posting errors.
These activities support more accurate A/R reporting and reduce the risk of pursuing amounts that are not actually owed by the insurance company.
Aging Worklist Monitoring and Recovery Reporting
Practice owners need to understand what is happening to older balances, not simply how many claims have been contacted.
PROMBS provides revenue cycle reporting, A/R aging analysis, payer performance monitoring, and denial trend reviews.
These activities help practices identify where older receivables are concentrated and which issues require additional attention.
For example, a practice may discover that its over-120-day balances are concentrated among a particular payer or provider group.
Further investigation may reveal a recurring payment issue or a billing workflow problem that needs correction.
By combining reporting with ongoing claim follow-up, our services help practices monitor outstanding reimbursement more systematically.
Billing Audits and Long-Term Revenue Cycle Improvement
An aging A/R backlog may reveal broader problems involving delayed charges, rejected claims, authorization gaps, or inconsistent payment posting.
PROMBS’s billing audits help healthcare practices investigate these issues and identify opportunities to improve their revenue cycle operations.
Our services extend beyond working existing claims to support charge capture, coding accuracy, denial management, and claim processing.
The goal is to help practices manage current unpaid accounts while addressing avoidable problems that contribute to future aging.
No billing company can guarantee collection of every older claim. Recoverability depends on coverage, documentation, applicable payer requirements, contractual terms, and available dispute rights.
A structured recovery process helps practices make better-informed decisions about those opportunities.
Frequently Asked Questions About Medical Accounts Receivable Over 90 Days
What does medical accounts receivable over 90 days mean?
It refers to outstanding medical billing balances that have remained unpaid for more than 90 days under the report’s aging method.
For physician practices, HFMA’s standardized billed A/R measurements generally use the date of service and separate older balances into 91–120 and over-120-day categories.
What percentage of medical A/R over 90 days is acceptable?
There is no single percentage that accurately describes every practice.
Results depend on specialty, payer mix, billing processes, service volume, and the reporting method.
Practices should use consistent definitions, compare historical results, and investigate unusual payer-specific patterns rather than relying on an arbitrary universal threshold.
Should medical claims older than 90 days be written off?
No. A claim should not be written off simply because it is older than 90 days.
The billing team should verify the claim’s status, remaining recovery rights, expected reimbursement, and payment history.
Any adjustment or write-off should follow the practice’s established financial controls.
How often should billing teams review A/R over 90 days?
A dedicated worklist should be reviewed at least weekly, with more frequent action for claims approaching important deadlines or requiring urgent escalation.
High-volume practices may need daily follow-up activity.
The appropriate schedule depends on claim status, payer requirements, staff capacity, and recovery priorities.
Which insurance payer should a medical practice follow up with first?
The practice should consider verified deadlines, outstanding reimbursement opportunities, unresolved claim issues, and the actions required.
The payer with the largest balance is not always the most urgent.
For example, a smaller claim approaching a valid appeal deadline may need attention before a larger claim still undergoing normal adjudication.
Can medical A/R over 120 days still be recovered?
Yes. Some claims older than 120 days remain recoverable when valid payment, reconsideration, or appeal opportunities exist.
The team should investigate the applicable claim history and payer rules.
The 120-day aging category is not itself a universal insurance filing or appeal deadline.
What if an insurance claim is paid but still appears in the aging report?
The billing team should review the payment and remittance records.
The issue may involve delayed payment posting, an unapplied payment, an incorrect adjustment, or a reconciliation error.
The account should be corrected through the appropriate financial process rather than automatically pursued as an unpaid insurance claim.
Can outsourcing medical A/R follow-up help a practice?
Outsourcing can provide additional capacity for claim investigation, payer communication, denial management, and payment reconciliation.
However, the practice should confirm that the vendor uses accurate account data, tracks payer-specific deadlines, documents actions, and reports actual financial outcomes.
PROMBS offers these services as part of its medical billing and revenue cycle management support.
Identify Recoverable A/R With a Free PROMBS Billing Audit
Outstanding medical accounts receivable can create financial uncertainty when a practice does not know why claims remain unpaid or which accounts require immediate attention.
Aging reports provide useful information, but they are only the beginning.
The real improvement comes from understanding each payer’s processing requirements, verifying the actual outstanding balance, and assigning the appropriate recovery action.
A payer-specific worklist helps billing teams distinguish pending claims from denials, underpayments, posting discrepancies, and accounts requiring escalation.
It also helps practice owners understand whether older receivables are being resolved through actual collections or accounting adjustments.
Medical accounts receivable over 90 days should not remain an unmanaged backlog of unpaid claims.
With organized payer follow-up, timely investigations, accurate payment reconciliation, and consistent reporting, practices can identify legitimate reimbursement opportunities and prevent avoidable problems from continuing.
