If you run a practice in Texas — or in New Jersey, Ohio, Oklahoma, Arizona, or Washington — a new Medicare pilot that began in 2026 changes how certain procedures get approved and paid. If your practice performs pain management, orthopedic, neurology, or related procedures, it’s worth understanding now, before it affects your cash flow.
The short version
On January 1, 2026, the Centers for Medicare & Medicaid Services (CMS) launched the Wasteful and Inappropriate Service Reduction (WISeR) Model — a six-year pilot running through 2031. It adds a prior-authorization or pre-payment review step for a defined list of services that CMS considers prone to overuse, in six states. CMS contracts with third-party technology vendors who use AI and machine learning to review the affected claims. Services that should have prior authorization but skip it can face pre-payment medical review or denial.
The six states in the pilot: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington.
Which services are affected
This is the key point: WISeR targets specific procedures, not routine office visits. The initial list includes services such as:
- Electrical nerve stimulation and destruction of nerve tissue
- Steroid injections for pain
- Bone cement injections for vertebral compression fractures
- Cervical (spine) fusion
- Knee arthroscopy for osteoarthritis
- Spinal decompression for stenosis
- Skin substitutes
- Incontinence control devices and impotence treatments
In other words, the practices most directly affected are pain management, orthopedics, neurology, and the specialties that perform these procedures. CMS can change the list over time, so the safest move is to check the current targeted-service list against your own procedure mix.
Why this matters for your revenue cycle
Prior authorization is one of the most common — and most preventable — causes of denied claims. Initial claim-denial rates have been climbing: payers denied about 11.8% of claims in 2024, up from roughly 10% a few years earlier, with medical-necessity and information-request denials driving much of the increase. Adding a new authorization gate on Medicare procedures in your state raises the stakes:
- A missed authorization is a hard denial, not a quick fix — meaning rework, resubmission, delayed cash, or lost revenue if appeal windows close.
- The administrative load lands on your team, who now have to know which procedures require the step and document medical necessity up front.
- Cash flow timing shifts. Even approved claims can take longer when a pre-payment review is involved.
What practices should be doing now
- Map your procedures against the WISeR list. If you perform any targeted services in one of the six states, flag them now.
- Build the authorization check into your front-end workflow — submit and document before the service, not after a denial.
- Watch your denial reports for a new pattern. A spike in authorization-related denials in 2026 is an early signal of a workflow gap.
- Keep documentation tight. Pre-payment review means a reviewer may look before paying — your notes need to stand on their own.
How AMS Solutions helps
This is exactly the kind of payer-rule change a dedicated revenue cycle team is built to absorb. AMS Solutions works Medicare fee-for-service, Medicare Advantage, and commercial plans every day, and we track authorization and medical-necessity requirements as they change — so a new step like WISeR becomes part of a managed workflow rather than a surprise on your denial report.
For orthopedic, pain management, and neurology practices in the affected states especially — where these procedures carry real revenue — getting ahead of WISeR protects collections and keeps your team focused on patients instead of paperwork.
Frequently Asked Questions
Which states does the WISeR model apply to?
The WISeR pilot operates in six states: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. It applies to traditional Medicare fee-for-service in those states and runs through 2031.
Which services require prior authorization under WISeR?
WISeR targets a defined list of procedures CMS considers prone to overuse — including electrical nerve stimulation, steroid injections for pain, cervical spine fusion, knee arthroscopy for osteoarthritis, spinal decompression, skin substitutes, and similar services. It does not apply to routine office visits, and CMS can update the list over time.
What happens if I miss the prior authorization?
A targeted service submitted without the required prior authorization can be subject to pre-payment medical review or denied. Building the authorization step into your front-end workflow — and documenting medical necessity up front — is the most reliable way to avoid those denials.
