Federal Medicare Prior Auth Model Now in Effect in Arizona; CMS Issues New Guidance
Federal AI-Driven Medicare Review Program Now in Effect in Arizona; CMS Issues Updated Guidance
A controversial federal pilot program using artificial intelligence and other processes to review and potentially deny certain Medicare claims is now in effect in Arizona and five other states, despite ongoing concerns from physicians about inappropriate denials of necessary care.
The Wasteful and Inappropriate Service Reduction program, known as WISeR, launched January 1 and represents a significant departure from traditional Medicare's typical operations. The six-year pilot requires prior authorization for specific medical services through private companies using enhanced technologies, including AI algorithms.
Arizona joins New Jersey, Ohio, Oklahoma, Texas, and Washington in the program, which collectively covers one in five traditional Medicare beneficiaries nationwide. Approximately 744,000 Arizonans enrolled in traditional Medicare are affected — roughly half of the state's 1.5 million Medicare enrollees.
According to federal officials, the goal of the pilot program is to cut back on fraud and abuse in Medicare. However, healthcare experts remain concerned about unintended consequences.
CMS Issues Updated Implementation Guidance
The Centers for Medicare & Medicaid Services released updated frequently asked questions addressing operational concerns about the program's rollout. Key updates include:
Electronic Portal Availability: CMS is working with WISeR participants to implement electronic portals by January 5, 2026, for providers to submit prior authorization requests. Participants unable to deliver operational portals will face payment penalties or other corrective actions.
Interim Submission Process: Until electronic portals are operational, providers can submit prior authorization requests through their Medicare Administrative Contractor (MAC), though processing may take longer than the standard 72-hour turnaround time. Alternatively, providers may choose not to submit prior authorization requests, though claims for services provided on or after January 15, 2026, would then be subject to pre-payment medical review.
Turnaround Time Requirements: The 72-hour turnaround time for requests submitted through electronic portals applies starting January 5, 2026, for dates of service on or after January 15, 2026. CMS will monitor compliance with this requirement and implement corrective actions for failures to meet the deadline.
The full FAQ is available on the CMS website.
Medical Organizations in Arizona, Other Pilot States Opposed the Program's Implementation
The Arizona Medical Association and other medical organizations nationwide took a prominent role in opposing the program's implementation.
In a letter to CMS Administrator Dr. Mehmet Oz, ArMA President Dr. Jason Jameson, along with medical association leaders from the other affected states, requested a halt to the program and asked that the agency "work collaboratively with stakeholders to design payment processes that protect the Medicare Trust Fund while achieving value, without jeopardizing patient access."
