Pain management practices have been dealing with rising prior auth denials for a while now. In 2026, two things happened at the same time that made it noticeably worse.
Medicare Advantage plans rejected 7.4% of pain management authorization requests in 2025. Three years earlier, that number sat at 5.9%. That is a 25% climb, and 2026 is tracking higher. Across every major payer category, denial rates rose 31% year over year.
Then in January, CMS launched a model called WiSeR and brought prior authorization to Original Medicare for the first time. Practices in six states now need approval for procedures they used to bill without any authorization at all. A lot of those practices are still figuring out what that means for their workflows.
Key Takeaways
- Medicare Advantage denial rate for pain management: 5.9% in 2023, up to 7.4% in 2025, a 25% increase in two years
- Prior authorization denials up 31% year over year across all payers in 2026
- CMS WiSeR model active since January 15, 2026 in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington
- 13 procedure categories now require prior authorization in Original Medicare under WiSeR
- Covered procedures include epidural steroid injections, nerve stimulator implants, percutaneous vertebral augmentation, and lumbar decompression
- CMS is planning a WiSeR gold card exemption pathway for qualifying practices by mid-2026
Why Are Pain Management Prior Auth Denials Rising So Fast?
The numbers have moved in one direction without stopping. In 2023, Medicare Advantage plans denied 5.9% of pain management prior authorization requests. By 2025 that rate was 7.4%. Epidural steroid injections, radiofrequency ablations, and spinal cord stimulator placements are generating the bulk of those denials.
These are not obscure billing codes. They are the core procedures pain management practices bill every week. The 31% year-over-year increase across all payers in 2026 makes clear this is not a Medicare Advantage-specific issue. Payers broadly are applying clinical necessity criteria more strictly. Documentation that cleared review two years ago is getting flagged now. The threshold has shifted.
What Is the WiSeR Model and Does It Apply to Your Practice?
WiSeR stands for Wasteful and Inappropriate Service Reduction. CMS launched it through its Innovation Center on January 15, 2026. The short version: certain outpatient procedures in Original Medicare now require prior authorization or pre-payment review for the first time in the program’s history.
Before January 2026, an Original Medicare patient could receive most outpatient pain management or orthopedic procedures without any prior authorization. WiSeR ended that in six states: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington.
The procedures now requiring WiSeR authorization include:
- Epidural steroid injections for pain management
- Electrical nerve stimulator implants
- Percutaneous vertebral augmentation
- Percutaneous image-guided lumbar decompression for spinal stenosis
- Sacral nerve stimulation for urinary incontinence
- Skin and tissue substitutes
CMS reviews each request using a mix of AI and clinical review against existing Medicare coverage policies. The model runs through December 31, 2031, and CMS has indicated it may expand to more states and procedures as the pilot develops.
What Happens If Your Practice Operates Across Multiple States?
Multi-location practices run into something most single-location practices do not have to think about. In WiSeR states, Original Medicare patients need authorization for covered procedures. Outside those states, the old rules apply and no WiSeR approval is needed.
A practice with locations in Texas and Colorado, for example, needs to handle authorization differently depending on where each Original Medicare patient is treated. That kind of location-specific workflow is hard to manage manually. Most denials in these situations come from staff applying the wrong process to the wrong patient, not from documentation that was actually deficient.
The WiSeR Gold Card: What It Is and How to Qualify
CMS plans to pilot a gold card feature inside WiSeR around mid-2026. Practices with consistently high approval rates would stop needing to submit prior authorizations for covered procedures. They would be exempt from the review process altogether.
That is real relief if you can get there. The catch is that eligibility depends on your approval history. The submissions your practice is making right now are the ones that build that record. Practices without a clean, consistent submission process are making qualification harder before the pathway even opens.
What This Means for Your Practice
If your practice is in Arizona, New Jersey, Ohio, Oklahoma, Texas, or Washington and treats Original Medicare patients for pain management or orthopedic procedures, you are managing an authorization layer that simply did not exist before 2026. Add that to Medicare Advantage denial rates that climbed 25% in two years, and the administrative load on your billing team is genuinely different than it was.
The practices doing the best right now updated their workflows when WiSeR launched in January. Those still running the same process they used in 2025 are collecting less than they are billing. It is not always obvious until the denials stack up and someone runs the numbers.
Frequently Asked Questions
Does WiSeR apply to Medicare Advantage patients?
No. WiSeR only applies to Original Medicare fee-for-service patients. Medicare Advantage patients fall under each plan’s own prior authorization rules, which exist separately from WiSeR.
Which states are currently in the WiSeR model?
Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. Those are the six states across four Medicare Administrative Contractor jurisdictions included in the current pilot. CMS may add more states before the model ends in December 2031.
What happens if a claim is submitted without WiSeR prior authorization?
Claims for WiSeR-covered procedures submitted without an approved authorization can be flagged for pre-payment review or denied outright. Practices in affected states should not bill WiSeR procedures for Original Medicare patients without completing authorization first.
When is the WiSeR gold card pathway launching?
CMS has said mid-2026 for the pilot. Eligibility will be based on documented approval history, which means the authorization submissions your practice makes today are what determine whether you qualify when the pathway opens.
How is WiSeR different from Medicare Advantage prior authorization?
Medicare Advantage prior authorization is run by each private insurer on its own timeline using its own clinical criteria. WiSeR is run by CMS and its Medicare Administrative Contractors, covers only Original Medicare patients, and uses CMS coverage policies as the benchmark. They are separate systems and need to be managed separately.
How Cosentus Helps
Cosentus has been managing prior authorization for specialty practices for 25 years, across Medicare Advantage, commercial plans, and now Original Medicare under WiSeR. When CMS changes the rules, our team updates workflows before practices feel the impact, not after. Clients have seen revenue and collections growth of up to 30% by treating payer policy as part of their financial strategy rather than something to react to.
- Handling WiSeR prior authorization submissions across all 13 covered service categories in the six active states.
- Tracking Medicare Advantage denial rates by payer and procedure so practices can see exactly where the 25% increase is showing up in their specific case mix.
- Building the approval record practices need to qualify for the WiSeR gold card pathway when CMS opens it mid-2026.
- Managing appeals for denied WiSeR and Medicare Advantage requests within the payer timelines that protect the right to recover.
- Maintaining location-specific authorization workflows for practices in both WiSeR and non-WiSeR states.
- Monitoring WiSeR updates through December 2031, including potential expansions to new states and procedures, and adjusting workflows before the changes arrive.
