If you run or bill for a physical therapy practice, 2026 has already handed you a stack of new Medicare rules to sort through. Some of it is good news. Some of it will quietly eat into your revenue if nobody on your team catches it in time. And a few of the changes are the kind that sound small on paper but turn into denied claims fast if your billing team isn’t watching for them.
This year is a bit of a mixed bag for physical therapy. Medicare raised its payment rate on one hand, then trimmed value from certain codes with the other. Add in a higher documentation bar and a real jump in audit activity, and it’s easy to see why so many practice owners are asking their billing partners the same question: “What actually changed, and what do I need to do about it?”
Let’s walk through it in plain terms.
A Quick Look at the 2026 Numbers
Before getting into the details, here’s a snapshot of the figures that matter most for physical therapy billing this year.
| 2026 Metric | 2025 | 2026 |
|---|---|---|
| Conversion Factor (non-APM) | $32.35 | $33.40 |
| KX Modifier Threshold (PT/SLP combined) | $2,410 | $2,480 |
| Targeted Medical Review Threshold | $3,000 | $3,000 |
| MIPS Performance Threshold | 75 points | 75 points |
| New RTM Codes | — | 98979, 98984, 98985 |
The Conversion Factor Went Up — But Don't Celebrate Yet
For years, the Medicare conversion factor kept sliding, and physical therapy practices absorbed a little less pay per visit each cycle. That trend finally reversed in 2026. For the first time ever, CMS split the conversion factor into two separate rates: $33.40 for most outpatient practices, and a slightly higher $33.57 for providers in a qualifying Alternative Payment Model. Either way, it’s a real increase from last year’s $32.35.
Here’s the catch. CMS also applied what it calls an “efficiency adjustment,” a downward tweak to the value of certain non-time-based codes, based on the idea that providers have gotten faster at delivering those services over the years. The result is that even with a higher conversion factor, many physical therapy practices are projected to see close to a flat or even slightly negative change in overall reimbursement once everything nets out.
There’s a silver lining here worth knowing about. After pushback from the APTA during the rulemaking process, several of the most commonly billed physical therapy codes — including manual therapy and aquatic therapy — were pulled off the efficiency adjustment list entirely. Timed codes that make up the bulk of a typical physical therapy visit came through the final rule in better shape than the proposed version suggested. It’s a good reminder of why keeping an eye on which of your codes are timed versus non-timed matters more than ever this year.
The KX Modifier Threshold Moved — Update Your Systems
Every year, Medicare adjusts the dollar threshold above which a physical therapy claim needs a KX modifier attached to confirm that continued care is medically necessary. For 2026, that combined threshold for physical therapy and speech-language pathology services rose from $2,410 to $2,480.
This isn’t a hard cap on care. Patients can absolutely continue physical therapy past that dollar amount. What changes is the documentation burden. Once a patient crosses the threshold, your notes need to clearly justify why ongoing treatment is expected to keep improving or maintaining function — objective measures, updated goals, and a clear clinical rationale, not just a checkbox.
If your billing software or EMR still has the old $2,410 figure programmed into its alerts, that’s worth fixing this week. A missed KX modifier on a claim that should have one is one of the fastest ways to see an otherwise clean physical therapy claim get denied.
Not sure your billing system is flagging the right threshold, or want a second set of eyes on your claim accuracy before it becomes a denial? Talk to our physical therapy billing team — we'll walk through your current setup with you.
Remote Therapeutic Monitoring Just Got More Practical
Remote Therapeutic Monitoring, or RTM, has been part of the physical therapy billing conversation for a few years now, but the original rules made it hard to actually collect on. Under the old structure, a practice needed 16 or more days of device engagement in a 30-day period before a device supply code could even be billed.
A patient who used their device for 12 or 13 days generated nothing. 2026 fixes that gap. CMS added three new RTM codes — 98979, 98984, and 98985 — that allow billing with as few as 2 to 15 device days in a 30-day window, and management time requirements dropped as well. For physical therapy practices already using remote monitoring tools, or considering adding them, this is a genuine new revenue opportunity rather than a paperwork exercise that rarely pays off.
If your practice hasn’t looked seriously at RTM before because the old billing math didn’t work, this is the year to take another look.
Telehealth Got Extended — With a New Compliance Trap
The extension of telehealth flexibilities for physical therapy has been a recurring cliffhanger for a few years running, and 2026 brought some genuinely good news: coverage for PT, OT, and speech-language telehealth services was extended through December 31, 2027.
The catch is administrative rather than clinical. Physical therapy providers can no longer bill telehealth visits from a location, including a home office, that isn’t formally enrolled in PECOS as a practice location. Any provider who has been quietly doing telehealth from home without updating their enrollment is sitting on a stack of claims that could be denied regardless of how clinically appropriate the care was. This is worth checking before your next billing cycle, not after a denial shows up.

Audits Are Up — And They're Not Slowing Down
Industry data on Medicare’s improper payment rate under Part B, which covers most outpatient physical therapy billing, has been sitting in the range of 6 to 8 percent in recent reporting periods. CMS has responded by leaning harder into review activity. Audit probability for physical therapy practices is trending noticeably higher this year, and practices billing over $500,000 annually in Medicare volume are seeing some of the steepest increases in review frequency.
The good news is that audits overwhelmingly come down to the same handful of preventable issues: mismatched timed units, missing or late certifications, and documentation that doesn’t clearly support continued medical necessity. A practice with clean, consistent physical therapy documentation has far less to worry about here than one relying on shortcuts.
What This Actually Means for Your Practice's Revenue
Put together, the 2026 changes aren’t a straightforward win or loss for physical therapy practices. The conversion factor increase is real, but it’s mostly offset by the efficiency adjustment on non-timed codes. The KX threshold gave practices a little more breathing room before extra documentation kicks in. RTM finally became worth billing for shorter engagement periods. Telehealth survived another year, but only for practices that get their PECOS enrollment in order.
The net effect for most physical therapy practices is close to flat reimbursement, with meaningfully higher stakes around documentation and audit exposure. In other words: the money is roughly the same, but the cost of getting billing wrong just went up.
How Physical Therapy Practices Can Stay Ahead in 2026
A few practical steps make the biggest difference this year:
- Update your KX modifier alert thresholds in your EMR or practice management system now, not at year-end.
- Run a CPT frequency report to see how much of your physical therapy billing relies on non-timed codes affected by the efficiency adjustment.
- Confirm every telehealth service location, including any home offices, is properly enrolled in PECOS.
- Review your documentation templates to make sure functional outcome measures are being captured consistently, not just for KX-threshold patients.
- If you’ve avoided RTM billing in the past because of the old device-day requirement, revisit it under the new rules.

Frequently Asked Questions
What is the 2026 Medicare conversion factor for physical therapy?
For most outpatient physical therapy practices, the 2026 conversion factor is $33.40. Practices participating in a qualifying Alternative Payment Model use a slightly higher rate of $33.57.
Did Medicare cut physical therapy reimbursement in 2026?
Not exactly. The conversion factor went up, but an efficiency adjustment on certain non-timed codes offset much of that increase, leaving many practices close to flat overall.
What is the KX modifier threshold for physical therapy in 2026?
The combined threshold for physical therapy and speech-language pathology services is $2,480 for 2026, up from $2,410 in 2025.
Does the KX modifier threshold mean therapy is capped?
No. Patients can continue physical therapy past the threshold. The KX modifier simply signals to Medicare that continued care is medically necessary and documented accordingly.
What is the Medicare targeted medical review threshold for physical therapy?
It remains $3,000 for 2026. Claims above this amount may be selected for a closer review based on CMS risk criteria, though it doesn’t trigger an automatic audit.
Are the new RTM codes relevant to physical therapy practices?
Yes. The three new codes added for 2026 — 98979, 98984, and 98985 — lower the device-engagement requirement from 16 days to as few as 2 days in a 30-day period, making Remote Therapeutic Monitoring billable in more situations than before.
Is physical therapy telehealth still covered by Medicare in 2026?
Yes, telehealth coverage for physical therapy was extended through December 31, 2027. However, providers must have every service location, including home offices, properly enrolled in PECOS.
Why are physical therapy Medicare audits increasing in 2026?
CMS has intensified its focus on documentation and medical necessity across Part B services, which physical therapy billing largely falls under, leading to higher audit probability, especially for high-volume practices.
What documentation does Medicare require for physical therapy claims in 2026?
A signed and current plan of care, treatment minutes that match billed timed units, and objective functional outcome measures showing that care is producing measurable improvement.
How can a physical therapy practice stay compliant with 2026 Medicare changes?
By updating billing system thresholds, auditing CPT code mix for efficiency-adjustment exposure, confirming telehealth PECOS enrollment, and tightening documentation around functional progress — or partnering with a billing team that manages this on an ongoing basis.
Final Thoughts
Choosing a DME billing company is not a decision to rush. The right partner protects your cash flow, keeps your clean claim rate high, and frees your team to focus on patients instead of paperwork. The wrong one adds another layer of frustration on top of an already complicated reimbursement process.
Use the evaluation criteria above, ask the hard questions before signing anything, and treat any ranked list, including this one, as a starting point for your own research rather than a final answer. The supplier who does that homework upfront almost always ends up with fewer denials and faster payments down the road.
