Roughly 1,000 pages of documents produced by the Centers for Medicare & Medicaid Services relative to the opening months of its controversial AI prior authorization program outline sweeping issues including delayed approvals, miscommunication, and provider frustration, forming a substantial record of WISeR AI prior authorization documents now public through a federal lawsuit.
How These WISeR AI Prior Authorization Documents Became Public
The Electronic Frontier Foundation, a digital and privacy rights nonprofit, recently shared the documents it obtained regarding the Wasteful and Inappropriate Service Reduction Model through a Freedom of Information Act lawsuit filed back in March. The trove includes participation agreements between the agency and six tech vendors, internal guidelines outlining the program and how vendors were selected, status report correspondences from Medicare Administrative Contractors and providers, and responses to feedback regarding one of the tech vendors, Innovaccer. The records run into April 2026, with EFF noting CMS is continuing to produce records it intends to publish.
The Program’s Basic Structure
CMS first rolled out the Innovation Center model in June, launched it Jan. 1, and plans to conclude the test run at the end of 2031. The program uses AI to expand the scope of prior authorization in traditional Medicare for certain services seen as vulnerable to waste, fraud, and abuse, and is active in Arizona, Ohio, Oklahoma, New Jersey, Texas, and Washington.
The Delays Documented Within These WISeR AI Prior Authorization Documents
The records outline thousands of prior authorization requests in which turnaround exceeded the pilot’s three-day goal. That includes several hundred that were still unanswered as of the end of March, one of which was 83 days old.
Technical and Communication Breakdowns
Other program updates outlined issues in which miscommunications between tech vendors and Medicare Administrative Contractors led to breakdowns in required processes, or mis-categorization of some providers’ approval requests. The logs also include reports of system downtime that delayed responses to approval requests, and multiple complaints from providers about delays or a lack of communication from Innovaccer, which is processing requests in Ohio.
Provider Accounts Within These WISeR AI Prior Authorization Documents
Provider feedback submitted to CMS described patients experiencing significant distress amid delays awaiting approval or guidance tied to the model, with one submission noting that even brief delays are already difficult for vulnerable patients, but that waiting weeks for answers becomes unacceptable. Another provider feedback form, written in all capital letters, described watching multiple patients in visible distress while awaiting authorization decisions for kyphoplasty and vertebral augmentation procedures.
Innovaccer’s Own Acknowledgment of Implementation Delays
Innovaccer told CMS ahead of the Jan. 1 start that it would need more time to fully implement its systems, with several letters in the documents outlining its gradual, though still ongoing as of early April, progress developing multiple features and clearing request backlogs. Other vendors also appear to have experienced technical issues before and after the program’s launch.
What EFF’s Analysis of These WISeR AI Prior Authorization Documents Highlights
EFF’s breakdown of the documents underscores that CMS’s payment methodology for WISeR vendors incentivizes more denials through limited payment reductions based on a vendor’s aggregate quality scores. The group also pointed to plans outlined in CMS’s documents to include additional medical services beyond the program’s initial 13, such as air ambulance transport, MRI scans, and some high-cost Part B medications.
Why This Expansion Plan Raises the Stakes
EFF said the records released so far echo concerns providers have raised since WISeR launched, including long delays, financial incentives to deny care, and technical problems, while noting that important questions remain about the AI systems private companies are using to inform decisions about Medicare benefits. Given the documented delays and technical failures within the initial 13-service scope, expanding into additional high-cost categories like MRIs and air ambulance transport could compound the same operational problems across a substantially larger set of services and patients.
The Political and Legal Backdrop Behind These WISeR AI Prior Authorization Documents
The WISeR model has faced pushback from providers, including the American Hospital Association and American Medical Association, and lawmakers, primarily Democrats, over concerns of improperly delayed care. An early report from a group of Washington state hospitals outlined substantial increases in the average time for an urgent or standard authorization during the program’s first month.
The Failed Senate Rollback Attempt
Legislators in the Senate attempted to advance a bill to roll back the WISeR model, though that was rejected in July on a party-line 46-50 vote. That vote came just a week after the U.S. Government Accountability Office determined that the model is subject to the Congressional Review Act, meaning it should have been submitted to Congress prior to implementation, a procedural finding that did not ultimately halt the pilot.
What These WISeR AI Prior Authorization Documents Mean Going Forward
With CMS continuing to produce additional records EFF intends to publish, the full scope of documented delays, technical failures, and vendor performance issues may continue expanding beyond what has already been disclosed through April 2026. Given the specific financial incentive structure EFF identified, tying vendor payment reductions to aggregate quality scores rather than directly penalizing high denial rates, providers and patient advocates may push for CMS to reconsider this payment methodology before the program’s planned expansion into additional service categories.
What to Watch Going Forward
As CMS continues releasing records under EFF’s ongoing FOIA litigation, industry observers will likely watch whether the documented delays affecting Ohio specifically, tied to Innovaccer’s implementation struggles, improve as the vendor continues clearing its backlog, and whether similar issues emerge in the pilot’s other five states. Given the failed Senate rollback attempt and the GAO’s Congressional Review Act finding, these WISeR AI prior authorization documents may fuel renewed legislative efforts to challenge the program, particularly as CMS moves toward expanding its scope to include air ambulance transport, MRI scans, and additional high-cost medications.
