How are Modifiers 59, 25, and 91 used in Medical Billing

The point that makes a great difference in Medical Billing is its thorough understanding. Getting things right means the difference between financial nuisances and smooth payments.

The crucial thing for coders to thoroughly understand to make things clear is: how are modifiers 59, 25, and 91 used in Medical Billing. These codes act like translators, ensuring healthcare provider services are clear to insurance companies. Accurately using these codes confirms that the coders understand everything and that the providers get paid correctly.

These modifiers have a significant role in medical bills which ensure that healthcare providers are paid according to the services they provide.

But here the question arises why do these modifiers matter so much? And how do these specific modifiers function in the medical bill submission? Before this, you need to understand what is a modifier for Medical Billing.

Modifiers in medical coding are like transparency and precision tools. They provide essential details to the codes describing a healthcare provider’s services to ensure that the precise nature of the treatment is captured. By using modifiers, physicians can effectively depict a patient’s visit, ensuring they receive the proper reimbursement for the services they provide.

What is Modifier 59

59 Modifier in Medical Billing is more than just an add-on code. Coders are often curious to know when to use modifier 59. It is a way to signal that a physician provided a patient with multiple services in one session, but those services are distinct and independent of each other. It shows that the services are not converging but necessary in their own right.

What Is Modifier 59 Used For?

59 modifier code is a primary procedure code defining the main services. If additional procedures or services are not paired with the primary service, modifier 59 is added to the other service’s code. That explains to the insurance company that the service is independent and not part of the primary service.

Working Cycle

Here’s a brief guide for applying Modifier 59 in Medical Billing:

Bill Primary Service: Being primary procedure with modifier 59 code for the main service

Identify Additional Services: Detect any services or procedures not typically linked with the primary one.

Append Modifier 59: Attach modifier 59 with the extra service’s code.

Notify Insurance: This gives a signal to the insurer that the extra service is independent and not contagious with the primary service.

When To Use a Modifier 59

There are certain specific services, procedures, and conditions to use modifier 59 in Medical Billing which include:

• When the same healthcare professional or physician performs a service or procedure or service after related services or procedure on the same day.
• When the subsequent service or procedure is unrelated to the first service or procedure but is performed during the same session.

When Not to Use Modifier 59

• When the subsequent service or procedure is planned and part of the global surgical package for the first service or procedure.
• When different healthcare professionals or qualified physicians perform the subsequent service or procedure.
• When the subsequent service or procedure is performed on a different day than the first service or procedure.

Practical Modifier 59 Examples

• Suppose a patient comes to the hospital with a wounded arm and after addressing the wound, he asks for a separate unrelated mole removal. In such cases, both procedures are performed in the same session. But modifier 59 would differentiate that the mole removal procedure was an independent service.
• A patient visits an orthopedic surgeon for shoulder and knee pain. The healthcare provider gives injections in both areas during the same visit. Though injections are vaccinated in one session, each is an independent service. Modifier 59 can be attached to highlight the distinct nature of the additional procedure.

Common Misconceptions and Mistakes

There are some misconceptions about modifier 59 that it is universal and can be added whenever there is more than one service. This is not true; its use is for distinct procedural services.

Another misconception regarding the use of Modifier 59 is that it is for the services typically bundled together. For instance, if a patient visits a healthcare facility, gets a consultation during that single visit, and then a standard follow-up procedure is typically performed after consultation, in such a situation, Modifier 59 wouldn’t be accurate.

What Is Modifier 25?

The healthcare provider uses modifier 25 to describe a situation where a patient receives significant and independent evaluation and management (E&M) services on the same day as any other service or procedure. It differentiates from the insurance in that even though two procedures or services are performed on the same day they are independent and deserve separate reimbursement.

What Is Modifier 25 Used For?

This is a distinct scenario with a patient scheduling procedure and then needing an additional unrelated E&M service, Modifier 25 is added to the E&M service code. It conveys the signal to the insurance company that the consultation was independent of the primary procedure.

Working Cycle

Initial Lab Test: Bill the primary lab test code for the first instance.

Identify Multiple Tests Requirement: Highlight the reason behind the same lab test to be done multiple times in one day.

Append Modifier 91: Attach Modifier 91 to the lab test code for each subsequent test.

Notify Insurance: It signals the insurer that these tests are not mere repetitions but essential follow-ups.

When To Use Modifier 25

• When a healthcare provider provides separately identifiable evaluation and management (E/M) services as major surgery on the same day.
• When a physician provides significant and separately identifiable E/M services to the patient admitted to the hospital for observation. It is important to note that services are provided on the day of admission.
• When a physician provides significant and separately identifiable E/M services on the same day a patient visits the emergency department.

Inappropriate Use of Modifier 25 Examples

There are certain scenarios given below when modifier 25 should not be used:

• When the E/M service provided is part of the global surgical package for the major surgery.
• When a non-physician provider (NPP) gives the E/M service.
• When the E/M service is given during the pre-operative or post-operative period.

Practical Examples of 25 Modifier in Medical Billing

Imagine a patient scheduled for a minor surgical procedure that indicates unrelated symptoms such as a high fever. The physician performs a full evaluation (E&M service) before surgery. 25 Modifier in Medical Billing would be applied to the evaluation code.

A patient mentions acute allergies during regular check-ups (an E&M service). The physician then operates an allergy test on the same day. Since the check-up and test are distinct, Modifier 25 is used for the check-up code.

Common Misconceptions and Mistakes

Many people mistake modifier 25 for using it whenever an E&M service and other procedures are performed on the same day. For example, it would be inappropriate to use Modifier 25 for a routine post-procedure follow-up.

Consequences Of Inappropriate Use of Modifier 25

Do you know that inappropriate use of Modifiers can lead to largely serious implications in the healthcare industry?

Mistakes

Applying the ‘final’ modifier to procedures or codes without a genuine need for its consequences.

Consequences

Overusing the ‘final’ modifier can hinder proper claim processing, create confusion, and result in delayed or denied reimbursement.

The final modifier is used in scenarios when its implications are essential to represent the procedure or service provided accurately. Avoid adding modifiers to procedures or codes that don’t need specific restrictions. Doing so ensures that the billing process remains responsive and adaptable to changes in regulations, medical practices, and insurance requirements.

What Is Modifier 91

Modifier 91 is all about lab tests. Specifically, it highlights that a test was operated more than once for the same patient and on the same day, but it wasn’t just a repetition. It was essential to obtain subsequent follow-up on test results.

How Does It Work?

When a patient requires the same lab test to be operated multiple times on the same day to track changes such as blood glucose levels. In this scenario, Modifier 91 is added to the lab test code for the extra tests, indicating that tests have not been just repeated but are essential follow-ups.

Working cycle

Initial Lab Test: Bill the primary lab test code for the first instance.

Identify Multiple Tests Requirement: It is to confirm that the multiple tests done on the same day were necessary.

Append Modifier 91: Attach Modifier 91 to the lab test for each subsequent test performed.

Notify Insurance: It is to notify the insurer that the tests and procedures are essential follow-up.

When To Use Modifier 91

• Modifier 91 is used to manage the treatment of a patient if you repeat clinical laboratory tests on the same service date.
• If you need serial and multiple laboratory tests to treat a patient such as repeat blood glucose tests, then you can use modifier 91.
• You can use a modifier if you repeat a test using a distinct specimen drawn later the same day.

When Not to Use

• Avoid using modifier 91 if you repeat a test to verify results due to specimen inadequacy or equipment failure.
• Avoid using modifier 91 if you repeat a test to get a different result, like an additional drug level.
• Avoid using modifier 91 if you repeat a test as part of a screening program.

Practical Examples of Modifier 91

At the hospital, medical professionals may operate blood glucose tests for diabetic patients during the morning, afternoon, and evening to regulate and monitor insulin levels. Modifier 91 is used with the afternoon and evening tests to confirm that the later tests are follow-ups.

When a patient needs a blood transfusion, physicians may find it essential to perform several blood tests throughout the day to ensure the safety and compatibility of the transfusion. In such a situation, the additional tests would be billed with the application of Modifier 91.

Common Misconceptions and Mistakes

The main confusion arises from differentiating the repetition of tests due to quality issues or errors and subsequent necessary tests. Using modifier 91 for just repeating a botched test, instead of a medically necessary subsequent test, would be inappropriate.
