A number that is widely misdescribed
The Medicare therapy threshold is not a cap
There used to be a hard cap on Medicare physical therapy. There is not one now. What remains is a documentation threshold, and the difference matters if somebody has told you your benefit has run out.
$2,480 is a paperwork threshold, not the end of your benefit. Medicare's therapy threshold for 2026 is $2,480 for physical therapy and speech-language pathology combined. It is a documentation threshold and not a cap: past it we add the KX modifier and record why continued treatment is medically necessary, and your benefit carries on. A clinic that discharges you the week you approach that number is describing its own paperwork policy rather than a rule from Medicare.
For 2026 the KX modifier threshold is $2,480 for physical therapy and speech-language pathology combined, with a separate $2,480 for occupational therapy. When your cumulative therapy spend passes it, we add the KX modifier to the claim and our documentation has to show that continued treatment is medically necessary.
That is the whole of it. Your benefit does not stop. Medicare does not refuse to pay. What changes is the standard of justification, and the justification is our job rather than yours.
Why so many people believe otherwise
Because for many years there genuinely was a hard cap, and a whole generation of patients and a fair number of clinics learned the rule in its old form. The hard cap was repealed; the number survived in a different role, and the folk memory did not update.
There is also a less charitable reason. Documenting medical necessity past the threshold takes real clinical effort — objective measures, functional goals, a defensible account of why more treatment will change something. It is far easier to tell a patient their benefit has run out than to write that up. A clinic that discharges everybody the week they approach $2,480 is describing its own paperwork appetite and calling it a Medicare rule.
What we do at the threshold
We tell you where you are before you get there. Nobody should discover the threshold from a letter.
If continued treatment is genuinely justified, we add the KX modifier and document why — the measurements, the functional goals still outstanding, and what specifically will change with more treatment. That is a normal part of the job.
If it is not justified, we say so, and that answer has nothing to do with the threshold. Somebody who has stopped improving does not need more visits regardless of what number they have reached, and somebody who is still improving should not be discharged because of a figure on a spreadsheet. The threshold changes the paperwork, not the clinical decision.
The targeted review, which is worth knowing about
Above a considerably higher figure, claims can be selected for targeted medical review. That is not automatic and not universal, and it does not mean payment is refused — it means the documentation gets read. If your care ever reaches that territory we will tell you, and the answer will still be the same: the records either support continued treatment or they do not.
None of this is a reason to ration your own care in advance. People do this — spacing appointments to make a benefit last, declining the visits they need in the first fortnight so there is something left in month three. It is almost always the wrong trade, because the early visits are where the leverage is.

How this works in practice
We tell you your cumulative position
Before you approach the threshold, not after. Nobody should find this out from a letter.
Past $2,480 we add the KX modifier
A normal claim, with documentation that continued treatment is medically necessary.
The documentation is our job
Objective measures, outstanding functional goals, and what specifically will change with more treatment.
The clinical decision is unchanged
If you have stopped improving you do not need more visits, whatever number you are at. If you are improving, the number is not a reason to stop.
We tell you if a targeted review is likely
It means the records get read, not that payment is refused.
Questions we are actually asked
The Medicare therapy threshold is not a cap — frequently asked
Is there a cap on Medicare physical therapy?
Not a hard one. The old therapy cap was repealed. What exists now is the KX modifier threshold — $2,480 for 2026 for physical therapy and speech-language pathology combined — which triggers a requirement to attest and document medical necessity. Your benefit continues past it.
My clinic told me my Medicare therapy benefit ran out. Was that true?
Not as a rule of Medicare. It may have been true that they had decided not to document past the threshold, or that they judged you had stopped improving — the second is a legitimate clinical conclusion, but it is a conclusion about you rather than about your benefit, and it should have been explained as one.
Does occupational therapy share the same threshold?
No. Occupational therapy has its own separate $2,480 threshold for 2026. Physical therapy and speech-language pathology share one between them.
What is the KX modifier?
A code we add to a claim above the threshold, attesting that the services are medically necessary and that our records demonstrate it. Adding it is routine; being able to support it is the part that requires real documentation.
Should I space out my visits to make the benefit last?
Usually not, and we will argue against it. The early visits are where the leverage is in almost every condition — particularly after joint replacement, where range not recovered in the first six weeks is very hard to regain. Rationing the front of a course to preserve the back of it generally makes the whole course longer.

Book an appointment
The booking page shows each therapist's own diary rather than a generic grid, so a slot you can see is a slot that is genuinely free. Most people do not need a doctor's referral to start — New York's direct access law runs to ten visits or thirty days — though Workers' Compensation, No-Fault and Medicare each need one from the first visit. If you are not sure which of those you are, telephone and we will work it out before you book.
