What is the WISeR Program?
The Wasteful and Inappropriate Service Reduction (WISeR) initiative represents a significant shift in how traditional Medicare will operate. Starting January 1, 2026, the Centers for Medicare & Medicaid Services (CMS) will introduce prior authorization requirements to traditional fee-for-service Medicare—a program that has historically operated without such restrictions. This groundbreaking change will fundamentally alter how healthcare providers deliver care to Medicare beneficiaries in six pilot states.
The program aims to reduce unnecessary medical procedures and control healthcare spending, but it has sparked considerable debate within the healthcare community. The initiative will run for six years, from January 1, 2026, through December 31, 2031, giving CMS ample time to evaluate its effectiveness and impact on patient outcomes.
Timeline and Implementation Details
CMS released a comprehensive provider and supplier operational guide on October 10, outlining the implementation process for affected healthcare facilities. The document provides detailed instructions for providers who must adapt to the new prior authorization requirements. Notably, CMS has already made one significant adjustment: the agency announced it would delay including deep brain stimulation procedures in the initial rollout and will reevaluate this service category at a later date.
Earlier in 2025, CMS Administrator Dr. Mehmet Oz publicly supported insurers working to simplify existing prior authorization processes, acknowledging the administrative burden these requirements create. This endorsement came despite growing concerns from medical professionals about the time-consuming nature of authorization paperwork.
Affected Medical Services and Procedures
The WISeR program will require prior authorization for several high-cost and frequently utilized medical services, including:
- Deep brain stimulation for Parkinson’s disease (delayed for reevaluation)
- Epidural steroid injections for pain management
- Cervical fusion procedures
- Various other specialized treatments and interventions
These services were selected based on utilization patterns, cost considerations, and potential for inappropriate use. However, healthcare advocates argue that many of these procedures are medically necessary and that authorization delays could harm patient outcomes.
Six Pilot States Leading the Initiative
The WISeR program will initially launch in six strategically selected states representing diverse geographic regions and healthcare markets:
- Arizona
- Washington
- New Jersey
- Texas
- Ohio
- Oklahoma
Healthcare providers in these states must prepare for the new authorization requirements by updating their administrative systems, training staff, and establishing new workflows to comply with CMS guidelines.
Healthcare Industry Opposition and Concerns
American Hospital Association Pushback
The American Hospital Association (AHA) has been among the most vocal critics of the WISeR initiative. In an October 23 letter to CMS, the organization called for delaying the program by at least six months to allow adequate preparation time. The AHA outlined several critical recommendations, including:
- Establishing clear guardrails for artificial intelligence use in the authorization process
- Altering the vendor payment methodology to ensure fairness
- Providing additional implementation support for healthcare facilities
Physician Burden Concerns
According to an American Medical Association (AMA) survey, physicians and their staff currently spend approximately 12 hours per week managing prior authorization paperwork. Healthcare providers worry that adding these requirements to traditional Medicare will significantly increase this administrative burden, taking valuable time away from patient care.
Congressional Resistance to WISeR
The program has faced substantial political opposition, particularly from House Democrats who have scrutinized the initiative’s reliance on artificial intelligence for expediting authorization decisions. Lawmakers have introduced resolutions opposing the WISeR program, citing concerns about patient access to care and the potential for AI-driven denials.
In a significant development, the House Appropriations Committee advanced a 2026 spending bill containing an amendment that would block funding for the pilot program. Representative Lois Frankel, who introduced the amendment during a September 9 meeting, stated: “Let’s not bring this nightmare to Medicare, the one program that seniors still count on for guaranteed straightforward care.”
Impact on Healthcare Providers
Medical facilities in the six pilot states must now prepare for substantial operational changes. Providers will need to:
- Implement new authorization request systems
- Train administrative staff on CMS requirements
- Adjust patient scheduling to accommodate authorization timelines
- Potentially hire additional staff to manage the increased paperwork
The financial and operational implications remain uncertain, particularly for smaller practices and rural healthcare facilities with limited administrative resources.
What Medicare Beneficiaries Need to Know
Traditional Medicare beneficiaries in pilot states should understand that some medical procedures may now require advance approval before treatment. This could potentially delay care, though CMS maintains the program aims to improve quality by reducing unnecessary procedures. Patients should communicate proactively with their healthcare providers about authorization requirements and expected timelines.
