Analysis based on AOTA's July 2026 OT Practice Capital Report on Medicare Part B technical payment policies, CMS's CY 2026 Physician Fee Schedule final-rule materials, and CMS therapy-services billing guidance.
AOTA's July 2026 Medicare Part B analysis is a reminder that occupational therapy payment can move because of small machinery inside the Medicare Physician Fee Schedule. The public debate often lands on conversion factors and annual cuts. The harder reading sits below the headline, where practice-expense formulas, old utilization crosswalks, and caregiver training billing rules can decide whether a code reflects the real cost of delivering skilled OT.
Why this is more than a coding dispute
Medicare Part B is the payment frame for many outpatient OT visits, private-practice services, and therapy delivered outside institutional prospective-payment systems. A small change in the Physician Fee Schedule can therefore reach staffing, scheduling, documentation time, service mix, and whether a clinic keeps accepting Medicare beneficiaries.
AOTA's new Capital Report focuses on technical policies that can sound remote from treatment. They are not remote for a practice trying to cover rent, front-desk time, billing work, compliance review, equipment, technology, supervision, and the slower clinical pace that often comes with complex functional care.
That is the practical value of the report. It tells OT readers to look past the annual payment headline and ask how CMS's formulas treat a discipline that bills under therapy rules, relies heavily on timed services, and often works with patients whose progress depends on caregiver carryover outside the clinic.
The IPCI issue is about overhead
AOTA points first to the Indirect Practice Cost Index, a practice-expense factor used inside the fee schedule. In plain language, indirect practice expense is the cost of running the practice around the clinician: space, administration, billing systems, scheduling, compliance, utilities, technology, and other overhead.
AOTA says the CY 2026 therapy indices show OT below the national average and below speech-language pathology, while CMS policy changes redistributed facility and non-facility practice expense in ways that can disadvantage services paid only at the non-facility rate. The concern is not that OT suddenly became cheaper to furnish. The concern is that the payment math can make it look that way.
For OT practices, this is where local examples matter. A comment that says payment is too low may be easy to dismiss. A comment that explains the overhead required for splinting, pediatric caregiver coordination, fall-prevention visits, cognitive and ADL intervention, documentation review, and Medicare billing can show CMS what the formula may be missing.
Old crosswalks can still shape current payment
AOTA also highlights an older therapy utilization crosswalk used to assign specialty practice-expense assumptions to therapy codes. Crosswalks are easy to ignore because they feel like background infrastructure. They become important when old assumptions continue to influence modern payment for OT services.
Occupational therapy and physical therapy share many outpatient therapy codes, yet the disciplines do not always carry the same overhead profile, visit structure, caregiver demands, equipment needs, or documentation burden. A crosswalk that once looked administratively convenient can become a source of undervaluation if it no longer reflects how care is actually delivered.
The CY 2027 rulemaking cycle is the next obvious place to watch this issue. Practices should not wait for the proposed rule to start collecting examples. The strongest evidence will come from real operations: appointment length, non-billable coordination, supply costs, interpreter or caregiver participation, documentation time, denials, and the service lines that become hard to sustain when payment falls behind cost.
Caregiver training has a billing problem
Caregiver training is one of OT's clearest Medicare access issues because functional progress often depends on what happens between visits. A caregiver may need skilled instruction for transfers, positioning, bathing routines, dementia strategies, sensory supports, splint use, home exercise follow-through, or safe task setup.
CMS has added and refined caregiver training payment over recent rule cycles, but AOTA's July analysis says billing requirements can still block payment when the caregiver training is clinically appropriate and the patient is not present in the way the rule requires. That distinction matters for OT. There are legitimate moments when caregiver instruction is necessary, skilled, and tied to the plan of care even when the patient cannot participate directly in the session.
The policy question is how Medicare can recognize caregiver training without opening the door to vague education claims. OT has a useful answer: require a clear link to the treatment plan, functional goals, caregiver role, skilled teaching, safety need, and expected carryover. The record should show why the training is therapy, not a general conversation.
CMS files are part of the work
CMS's CY 2026 Physician Fee Schedule final-rule page includes downloadable files for specialty impacts, indirect practice cost indices, practice-expense methodology, selected procedure payment, telehealth, and therapy-related payment lists. Those files are heavy reading, and they are the bridge between a rule summary and what a clinic sees in payment.
An OT owner or rehab director does not need to become a fee-schedule actuary to use them well. Start with the codes that carry the practice. Compare the payment direction with actual costs. Check where timed treatment, evaluations, orthotic work, caregiver training, and documentation-heavy services are most exposed. Then decide which examples should be elevated through AOTA, state associations, direct CMS comments, or payer conversations.
The same discipline helps students and job seekers. A setting with high autonomy and meaningful occupation-based work may still be fragile if Medicare Part B payment does not cover the real cost of care. Reimbursement literacy is becoming part of career literacy.
What to do before the 2027 proposal lands
The immediate task is preparation. Practices should identify their highest-volume OT codes, compare reimbursement trends against overhead, document caregiver training scenarios that are clinically necessary, and collect access examples: reduced appointment availability, closed Medicare panels, shortened visits, dropped services, or staffing choices driven by payment pressure.
Comments should be specific and restrained. CMS needs to see what is happening at the code and practice level, beyond a general statement that OT is valuable. The stronger submission explains the patient population, the service, the cost driver, the policy mechanism, and the access consequence.
AOTA's July report gives the profession a useful reading assignment before the CY 2027 Physician Fee Schedule debate accelerates. For OT, the most important Medicare payment story may be the one hidden inside the spreadsheet.
