CMS's November 4 final rule, fee-schedule impact files, and therapy billing guidance
Occupational therapy practices planning for January have a final Medicare rule to work from. CMS released its 2027 Physician Fee Schedule on November 4, setting a higher OT KX modifier threshold and new remote-monitoring conditions while leaving clinics with payment figures that require a closer calculation.
In brief
- The $2,540 OT KX threshold takes effect in 2027; medically necessary care can continue beyond it.
- CMS's 3% combined PT/OT RVU estimate is separate from the lower conversion factors.
- New RTM patient and initiating-visit requirements begin in 2027; the direct-employment rule waits until 2029.
Read the payment numbers together
CMS lists a 2027 conversion factor of $32.63 for nonqualifying alternative payment model participants, down 2.31% from 2026. The qualifying APM factor is $32.95, down 1.83%. A temporary 2.5% increase provided for 2026 expires at year's end.
The separate specialty table estimates a 3% combined impact from relative value unit changes for the physical/occupational therapy category, driven by practice expense. That rounded category average does not establish a clinic's net payment change. The specialty impacts exclude the statutory conversion-factor updates and can differ from the services an individual practitioner furnishes. Geography, codes and the applicable conversion factor belong in the calculation.
Two thresholds need separate reminders
The final rule raises OT's annual KX modifier threshold from $2,480 to $2,540 for 2027. OT retains its own threshold, separate from the combined PT and speech-language pathology amount. Beyond that line, the KX modifier confirms that the record supports medically necessary services under Medicare's requirements. The former therapy cap has been repealed.
The targeted medical-review threshold remains $3,000 through 2027. Crossing it does not automatically select every claim for review. Billing teams should check that their software distinguishes the KX trigger from the review threshold before January claims begin.
Remote monitoring has two implementation dates
For 2027, remote therapeutic monitoring must be furnished to established patients, with a separately reportable initiating visit associated with the start of monitoring. CMS says a patient can become established after meeting the initiating-visit requirements. The visit can include other care; remote monitoring must be discussed, and telehealth use must meet Medicare's applicable requirements.
CMS delayed the requirement for remote-monitoring clinical staff to be direct employees of the practitioner or practice until January 1, 2029. It plans further guidance on appropriate staffing arrangements. A practice using a third-party service should review that longer transition alongside the requirements arriving in January. The delay alone does not settle whether a particular arrangement meets all billing rules.
Put a familiar visit through the new schedule
A practical next step is to price a few visits the clinic actually provides using the final code files and its locality. Include the usual units and applicable payment adjustments, then compare the result with the current allowance. Keep that worksheet beside the budget assumptions so the percentage has a service behind it.
Assign the KX software check and the RTM workflow review to named staff before year-end. A January schedule is easier to trust when the treating therapist and billing team have checked the same rules.
