Federal Medicare Prior Auth Model Now in Effect in Arizona; CMS Issues New Guidance

January 7, 2026

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."

ADHS Issues Standing Orders for Flu, COVID-19 Vaccine Access

By Admin User • September 18, 2026
Statewide orders keep pharmacists and physicians authorized to vaccinate Arizonans amid uncertainty over the next ACIP meeting. Statewide Orders Cover the 2026-27 Flu & COVID Season The Arizona Department of Health Services has issued statewide standing orders supporting access to the 2026-27 influenza and COVID-19 vaccines approved by the U.S. Food and Drug Administration. Arizonans seeking a flu or COVID-19 vaccine should contact their physician or pharmacy to confirm availability. Why the Orders Were Issued Arizona pharmacists may administer vaccines recommended by the Advisory Committee on Immunization Practices, vaccines recommended by the Centers for Disease Control and Prevention for international travel, or vaccines authorized under a prescription, including a physician-issued public health standing order. With the timing of the next ACIP meeting uncertain, ADHS worked with the Arizona Board of Pharmacy to issue statewide standing orders for the flu and COVID-19 vaccines, which function as a prescription allowing pharmacists and physicians across Arizona to administer them to anyone who wants one. ADHS Medical Advisor Weighs In "Vaccines are one of the most important tools we have to protect our communities. The Influenza and COVID-19 vaccines have been proven safe and effective at preventing severe illness, hospitalization, and death. Vaccines help us limit the spread of disease, reduce pressure on our healthcare system and reduce costs," said Dr. Richard Carmona, ADHS public health medical advisor and the 17th U.S. Surgeon General. "We have issued these standing orders to ensure safe and timely access to the vaccines in alignment with scientific and evidence-based guidance." What Arizonans Should Know The standing orders do not require every pharmacy to offer vaccinations, and they do not guarantee insurance coverage for administration. Coverage and out-of-pocket costs vary by plan, so Arizonans should check with their insurance provider before scheduling an appointment. 

Arizona Asks Supreme Court to Halt Prison Health Care Takeover

By Admin User • September 18, 2026
State attorneys seek an emergency stay after lower courts reject bids to delay receivership of the prison health care system. State Makes a Last-Ditch Appeal Attorneys for the Arizona Department of Corrections, Rehabilitation and Reentry asked the U.S. Supreme Court this week to delay a court-ordered receivership of the state's prison health care system. The request comes after both a federal district court and the 9th U.S. Circuit Court of Appeals declined to pause the takeover. In the recent application, former U.S. Solicitor General Paul Clement, a representative of the department, argued that the state deserves more time to make its case before surrendering control of its operations, including oversight of its employees and health care budget. Roots of the Case The dispute began in 2012 when inmates sued the department, alleging the prison system's inadequate medical, mental health, and dental care amounted to cruel and unusual punishment under the Eighth Amendment. The case went through years of litigation and a failed settlement agreement. In 2023, U.S. District Judge Roslyn Silver ruled that the health care system was "grossly inadequate." The court ordered the prison healthcare system to comply with more than 150 "quality indicators," but according to court-appointed monitors, the department failed to comply with 131 of the measures. In light of this finding, Silver named Annette Chambers-Smith, former director of the Ohio Department of Rehabilitation and Correction, to take over as receiver effective Oct. 19. Arguments on Both Sides Clement argues receivership should be the last resort and that Silver moved to it too quickly. He asserts that the department has made measurable progress, including growing its health care staffing by more than 50%, expanding substance-use treatment access, and adopting a new care model. Corene Kendrick, deputy director of the American Civil Liberties Union National Prison Project, which represents the roughly 25,000 people incarcerated in Arizona prisons, called the department's request a "Hail Mary" and said Silver had given the department years of opportunities to comply before ordering receivership. What Happens Next The Supreme Court has not yet set a deadline for the plaintiffs to respond to the stay request. Separately, the 9th Circuit is now reviewing the merits of the receivership order itself. The department filed its opening brief on Sept. 15, and the plaintiffs' response is due Oct. 15.
