CMS's new WISeR model does not currently require prior authorization for outpatient physical, occupational, or speech therapy. But the federal government's move to AI-driven prior authorization in traditional Medicare — live since January 1, 2026 — signals a broader policy direction every rehab clinic owner and biller needs to understand now, not when it lands on your doorstep.

What Is the WISeR Model? (The Plain-English Explanation)

On June 27, 2025, the Center for Medicare and Medicaid Innovation (CMMI) announced a new six-year payment model called the Wasteful and Inappropriate Service Reduction (WISeR) Model. It launched on January 1, 2026, as a pilot program in six states — Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington — running through December 31, 2031.

The model targets what CMS calls "low-value" services: procedures with limited evidence of clinical benefit for certain patients, a history of fraud or overuse, or both. CMS contracts with AI-powered technology vendors to review prior authorization requests for those specific services before treatment or to conduct post-service pre-payment review if no prior auth was submitted. The six participating vendors are Cohere Health, Genzeon, Humata Health, Innovaccer, Virtix Health, and Zyter.

This is the first time traditional Medicare — Original Medicare, fee-for-service — has introduced systematic prior authorization at this scale. Medicare Advantage plans have required prior authorization for years, but Original Medicare largely did not. WISeR changes that, at least for the services it currently covers.

Does WISeR Affect Physical, Occupational, or Speech Therapy?

No — not yet, and this distinction matters.

The American Occupational Therapy Association (AOTA) confirmed directly in its July 2025 guidance that "occupational therapy services are not currently included in the list of targeted services." The same is true for physical therapy and speech-language pathology.

The services WISeR currently covers are concentrated in surgical, procedural, and device categories. The table below shows exactly what is — and is not — inside the model's scope, as confirmed by CMS's Provider and Supplier Operational Guide (January 2026) and AOTA guidance (July 2025).

WISeR Model — What's Covered vs. What's Not (as of July 2026)

The key takeaway from this table: if a patient comes to your clinic for post-surgical rehab after a knee replacement, or for a routine course of physical therapy following a lumbar strain, WISeR does not create any new prior authorization step for your practice. The "indirect" column matters, though — if your referral pipeline runs through physicians or surgeons performing WISeR-covered procedures, their administrative burden increases, which can slow referral timelines.

Why Every Rehab Clinic Should Still Pay Attention

CMS has been explicit that the targeted service list can grow. AOTA's guidance warns practitioners that CMS "may expand the list of targeted services over time" and recommends staying informed about whether therapy services may be included at a later date. Federal reporting has described WISeR as a test case for broader AI-driven utilization management inside traditional Medicare — and if the model reduces wasteful spending, expansion is likely.

There's also a broader policy signal here that goes beyond WISeR itself. For the first time, the federal government is using AI to adjudicate Medicare coverage decisions at scale. A 2025 American Medical Association survey found that 94% of physicians said prior authorization delays necessary care, and 78% said patients abandon treatment due to authorization barriers. Those pressures are already well known to anyone running a therapy practice. WISeR extends that friction — at least for covered services — into Original Medicare.

For outpatient rehab specifically, the parallel threat is the CMS-0057-F Interoperability and Prior Authorization Final Rule (discussed in detail below), which does impose concrete technical requirements your EMR must be ready to meet by January 2027. The two policies are separate, but together they tell a clear story: prior authorization in Medicare is getting more automated, more complex, and more consequential for clinics that aren't prepared.

The WISeR Rollout: What's Actually Happening in the Pilot States

The six-state rollout began accepting prior authorization requests on January 5, 2026. In the months since, early reports from providers, policy analysts, and patients have been largely critical.

Reporting from outlets including The Washington Post and Medscape (March–April 2026) documented provider concerns about the rollout: cases where authorization decisions took longer than the federal timelines CMS-0057-F requires, instances where care within coverage guidelines was not authorized, and significant administrative complexity compared to existing payer PA workflows. The KFF Health Policy Research group published a detailed analysis in February 2026 noting that the model's structure — contracting with AI vendors to conduct prior authorization reviews — was unprecedented in Original Medicare and warranted careful monitoring of its effects on care access.

The design of the model has drawn scrutiny from provider associations. CMS's published model documentation confirms that participating technology vendors receive compensation tied to the savings generated by the model, which critics argue creates financial incentives that could conflict with clinical decision-making. Multiple specialty societies — including cardiology and pain management groups — formally opposed WISeR or called for its modification on these grounds ahead of launch.

Politically, the model is contested. Congressional Democrats introduced legislation to repeal WISeR, and a House Appropriations Committee amendment in June 2026 would bar CMS from spending funds on any prior authorization model in traditional Medicare for fiscal year 2027 — including WISeR. The model survived an earlier repeal attempt when a similar amendment was excluded from the Consolidated Appropriations Act of 2026 signed in February 2026. As of this writing, WISeR remains active in all six pilot states, but its long-term status is uncertain.

The practical lesson for rehab clinic owners: even if WISeR never touches therapy directly, its rollout is normalizing AI-reviewed prior authorization in Medicare, building the infrastructure, and setting political precedents that will influence the next four years of health policy. This is the landscape your practice is operating in.

The More Immediate Compliance Requirement: CMS-0057-F

While WISeR gets the headlines, the policy that has a hard deadline for your EMR is the CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F).

The non-technical provisions — including the requirement that payers issue prior authorization decisions within 72 hours for urgent requests and 7 calendar days for standard requests, and that they provide specific reasons for denials — took effect January 1, 2026. These apply to payers, not directly to your clinic, but they change what you should be able to expect from payers when you submit a PA request.

The technical provisions that matter for your EMR are scheduled for January 1, 2027. By that date, impacted payers must have implemented four FHIR-based APIs:

• Patient Access API — gives patients access to their own prior authorization data
• Provider Access API — allows providers to retrieve patient data from payers
• Payer-to-Payer API — enables data exchange when patients switch payers
• Prior Authorization API — allows providers to check coverage requirements and submit PA requests electronically via standardized FHIR interfaces

This last one is directly relevant to your workflow. If your EMR can connect to payer Prior Authorization APIs, your staff can check whether a planned service requires prior auth, see the exact documentation requirements, and submit the request electronically — all without logging into payer portals, sending faxes, or calling authorization lines.

For MIPS-eligible clinicians, prior authorization API use becomes an attestation option starting with the CY2027 performance period. Clinics that adopt early are positioned to demonstrate meaningful use of interoperability tools, which can support MIPS scoring.

The question to ask your EMR vendor today is straightforward: Is your platform building toward FHIR Prior Authorization API connectivity for the January 2027 deadline? If they can't answer clearly, that's a gap to take seriously.

What This Means for Each Role in Your Practice

If you're a clinic owner or director: Your two actions are to monitor the WISeR service list for any expansion toward therapy CPT codes, and to confirm that your EMR vendor has a credible plan for CMS-0057-F FHIR API readiness by 2027. The administrative burden and cash-flow impact of a poorly managed prior authorization process doesn't wait for a mandate — it costs you now, in staff hours, delayed starts, and uncollected revenue.

If you're a biller or RCM lead: WISeR creates a precedent for stricter documentation standards in prior authorization. Even though therapy is not currently covered, payers' internal documentation expectations are already tightening across the board, influenced by what Medicare is building. Your PA workflow should assume that documentation quality will be the deciding factor in approval speed — complete clinical notes attached at submission, correct CPT and ICD-10 codes, and payer-specific requirements met before the request goes out.

If you're a therapist or treating provider: The WISeR model uses "licensed clinicians using standardized, evidence-based criteria" to review cases. That framing — evidence-based, documented medical necessity — is what your SOAP notes will increasingly be judged against, whether by a WISeR vendor, a Medicare Advantage plan, or a commercial insurer. The therapist who documents medical necessity clearly and consistently in real time is the one whose patients' claims don't get delayed or denied.

If you're front-desk or scheduling: The expanded use of prior authorization in Medicare — even in its current limited scope — reinforces the importance of checking authorization status before the patient arrives, not the morning of their appointment. A missed auth for a covered service has the same cash-flow consequence whether it's a legacy commercial payer or a new Medicare model.

How AI-Native EMRs Are Changing the Prior Authorization Game

The WISeR model uses AI to review prior authorization requests on the payer side. What's less discussed is that clinics can deploy AI on their side of the same transaction — and the operational advantages are significant.

An AI-native prior authorization workflow reads the therapist's documentation, identifies what each payer requires based on the patient's plan and the planned CPT codes, prepares the submission packet automatically, and submits via portal or API. Staff intervene only when exceptions arise. The result is fewer missed authorizations, faster approvals, and more consistent cash flow.

SPRY's AI Prior Authorization engine, for example, extracts patient, diagnosis, and visit details directly from SOAP notes; predicts the required authorization type based on payer-specific rules; validates documentation completeness before submission; and tracks approval status with alerts for next steps. Based on SPRY's platform data, this approach delivers 80% of authorization requests fully automated for trained payer agents, with an average of 30+ minutes saved per request and turnaround cut from days to hours.

Across SPRY's RCM clients, the outcomes from combining AI prior authorization with integrated claim scrubbing include 50–75% fewer denials compared to baseline, 95%+ clean claim rates on first submission, and claims closing in 12–23 days — over 10 days faster than industry norms. Those numbers come from real clinic data across practices including Align Therapy, Excel, Bradley University, Kintsugi PT, and Optimal Performance PT.

That said, automation isn't a replacement for clinical judgment. An AI engine can ensure your documentation is complete and your submission is formatted correctly, but it works best when the underlying SOAP note is thorough and the therapist has clearly established medical necessity. Technology and clinical quality are complements, not substitutes.

Where SPRY's Prior Authorization Automation Is Today (Honest Assessment)

SPRY's prior authorization automation is currently live for major payers including Carelon/BCBS and UHC, with Humana and additional portals in progress. The AI agent logs into payer portals, completes the authorization form using data pulled from SPRY, and attaches clinical documentation automatically.

For payers not yet in the trained-agent network, SPRY's RCM team handles authorization manually using the same data pipeline, with failed or edge cases tagged with reference IDs and reconciled end of day. The goal is full automation across all payer portals, which is an ongoing build.

For payers with existing FHIR API connectivity, SPRY can also submit via API rather than portal — which is the architecture that will become standard as CMS-0057-F's January 2027 deadline approaches. SPRY's platform is designed around the native integration of clinical documentation and billing on one database, which is the foundational requirement for FHIR-based prior auth to work correctly — the clinical note and the authorization request need to live in the same system.

The FHIR Prior Authorization API standard (based on the Da Vinci Prior Auth Support FHIR Implementation Guide) is still maturing across the payer ecosystem. Full API connectivity for every payer in an outpatient rehab practice's mix is not something any EMR can promise today — but the architecture your EMR is built on determines how fast you can adopt it when payers are ready.

A Practical Checklist: What to Do in Your Clinic Right Now

Based on what WISeR and CMS-0057-F actually require today and through 2027, here is what outpatient PT, OT, and SLP practices should be doing — broken down by timeline and role.

What Good Prior Authorization Looks Like in a Rehab Practice

The clinics with the lowest denial rates in outpatient rehab share a few characteristics. They check eligibility and authorization requirements before the patient is scheduled, not after. Their therapists document medical necessity in real time, with the claim-relevant language — functional limitations, measurable goals, evidence-based treatment rationale — built into their normal SOAP note workflow, not added as a billing afterthought. Their billers review auth status as part of scheduling, not as a separate end-of-week reconciliation.

And they use technology that closes the loop between clinical documentation and authorization submission. When the note that justifies medical necessity is also the source document for the authorization packet, errors drop, turnaround shrinks, and the administrative burden on staff goes down. That's the workflow the CMS-0057-F API standard is ultimately designed to enable at scale.

Prior authorization in outpatient rehab is not a new problem, but 2026 is the year the policy and technology conditions are aligning in ways that will separate well-prepared practices from struggling ones. WISeR is the loudest signal. CMS-0057-F is the mandatory track. AI-native documentation and billing automation is the tool that makes both manageable.

Frequently Asked Questions

Does the WISeR model apply to physical therapy?

No. As of July 2026, WISeR does not include outpatient PT, OT, or SLP services in its list of targeted procedures. The model currently covers specific surgical and device-related services such as electrical nerve stimulators, skin substitutes, and knee arthroscopy for osteoarthritis in six pilot states. CMS has indicated the service list may expand over time, so rehab practices should monitor updates from APTA and AOTA.

Which states are in the WISeR pilot?

Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. The model applies only to patients on Original Medicare (traditional fee-for-service), not Medicare Advantage. It runs from January 1, 2026, through December 31, 2031.

What is the CMS-0057-F Prior Authorization Final Rule?

CMS-0057-F is a separate federal rule requiring impacted payers to implement FHIR-based APIs — including a Prior Authorization API — by January 1, 2027. The non-technical provisions (faster PA decision timelines, required denial reasons) took effect January 1, 2026. This rule applies to payers, but it directly affects how clinic EMRs and billing systems will interact with payers going forward.

Will WISeR be repealed?

That is uncertain. Congressional Democrats introduced repeal legislation in mid-2026, and a House Appropriations Committee amendment in June 2026 would prevent CMS from funding the model in fiscal year 2027. However, WISeR survived an earlier repeal attempt in the Consolidated Appropriations Act of 2026 signed in February 2026. It is currently active in all six pilot states.

How can my clinic reduce prior authorization denials right now?

The most effective interventions are: checking authorization requirements before scheduling (not at check-in), ensuring SOAP notes document medical necessity with specific functional limitations and measurable goals, using software that validates documentation completeness before submission, and tracking authorization status in real time so expired auths don't cause claim holds. Clinics using AI-native prior authorization automation consistently report fewer denials and faster turnaround than those relying on manual portal submissions.

Does SPRY handle prior authorization?

Yes. SPRY's AI Prior Authorization engine extracts clinical data from SOAP notes, identifies payer-specific requirements, prepares submission packets, and submits via payer portal or API. The system is currently live for major payers including Carelon/BCBS and UHC, with additional portals in progress. SPRY clients report 80% of authorization requests fully automated for trained payer agents, with 50–75% fewer denials compared to baseline.
