If you’ve heard about WISeR recently and aren’t sure what it means or how it might impact your Medicare care, you’re not alone.
The Wasteful and Inappropriate Service Reduction (WISeR) Model is a new Medicare pilot program designed to curb unnecessary or low-value medical services and improve the efficiency of Medicare spending. It represents a significant change to how some services are reviewed and approved in Original Medicare (Part A and Part B).
What Is the WISeR Model?
WISeR stands for Wasteful and Inappropriate Service Reduction. It is a pilot initiative from the Centers for Medicare & Medicaid Services (CMS), the agency that runs the Medicare Program, that uses advanced technology, along with clinical review, to determine whether certain services are medically necessary before Medicare pays for them.
In simple terms:
- Medicare has identified services that are considered high-risk for waste, overuse, or low clinical value.
- For those services, prior authorization (approval before treatment) may now be required.
- Requests are reviewed using enhanced data tools (such as artificial intelligence and machine learning) alongside established clinical guidelines. It is important to note that coverage decisions under the WISeR model are not based solely on these data tools. A human clinical reviewer is involved in all final coverage decisions when a service is recommended for denial.
The goal is to ensure Medicare pays for care that is medically appropriate and supported by evidence-based standards.
Where Is WISeR Being Piloted?
The WISeR Model is currently being tested in the following six states:
- Arizona
- New Jersey
- Ohio
- Oklahoma
- Texas
- Washington
If you live in one of these states and have Original Medicare, you may be affected — especially if your doctor recommends one of the services included in the program.
Medicare Advantage plans are not part of the WISeR Model, as they already use their own prior authorization and utilization review processes.
Which Services Are Included?
CMS has identified specific services that will require additional review in the pilot states. These include:
Musculoskeletal and Pain-Related Services
- Skin and tissue substitutes
- Epidural steroid injections for pain management
- Facet joint injections
- Sacroiliac joint injections
- Knee arthroscopy for osteoarthritis
- Cervical spinal fusion
- Lumbar spinal fusion
- Vertebroplasty and kyphoplasty
- Arthroscopic shoulder procedures
Neuromodulation and Implantable Devices
- Electrical nerve stimulator implants
- Peripheral nerve stimulation
- Spinal cord stimulation procedures
- Implantable pain pumps
- Neurostimulator trial procedures
- Replacement or revision of implanted nerve stimulators
Other Services
- Certain urological procedures for erectile dysfunction
- Select wound care services
If one of these services is recommended, your provider may need to obtain prior authorization before Medicare will pay for it.
How Could This Affect Your Care?
If you are enrolled in Original Medicare in one of the pilot states, you may notice:
Prior Authorization Requirements
Your provider may need to submit medical records or documentation before treatment can be approved.
Possible Delays
Reviews may take additional time, which could delay scheduling of a procedure.
Coverage Decisions Based on Medical Necessity
If Medicare determines a service does not meet established clinical guidelines, it may deny payment.
It is important to understand that the purpose of the program is to reduce inappropriate or unnecessary services — not to deny medically necessary care. However, additional review steps may require more coordination between patients and providers.
What Should Medicare Beneficiaries Do?
If you live in one of the affected states, consider the following steps:
- Ask your provider whether a recommended procedure requires prior authorization.
- Confirm that your medical records clearly document the need for the service.
- Carefully review any Medicare notices you receive.
- Understand your right to appeal if a service is denied.
Working with a knowledgeable insurance professional can also help you better understand how these changes may impact your coverage.

Conclusion
The WISeR Model is a Medicare pilot program designed to reduce waste and ensure certain services meet clinical guidelines before Medicare pays for them. If you are enrolled in Original Medicare and live in Arizona, New Jersey, Ohio, Oklahoma, Texas, or Washington, this program could affect how certain procedures are approved.
Staying informed, asking questions, and maintaining open communication with your provider are the best ways to navigate these changes confidently.
