Medicare's WISeR AI prior authorization pilot cut targeted services in six states

Medicare's AI-enabled prior authorization pilot is now measurably reducing care volume. According to a JAMA research letter published Oct. 26 and reported by Physicians Practice, epidural steroid injections fell 15 percent in the six states testing the WISeR model compared with trends in the rest of the country, and other targeted services fell about 20 percent. For injections, the drop eased from about 21 percent in the first quarter of 2026 to about 9 percent in the second. Other services moved only from 21 percent to 18 percent. Services slated for the pilot but never implemented showed no significant decline. The model runs through 2031 in Arizona, New Jersey, Ohio, Oklahoma, Texas and Washington.

MedCity News describes documents the Electronic Frontier Foundation obtained through a March 2026 Freedom of Information Act lawsuit against CMS. WISeR launched January 1, 2026, with six private technology companies reviewing requests. The records show Virtix Health rejected 53 percent of more than 6,000 requests over three months, which the company attributed to an influx of claims. One request sent to Genzeon went unanswered for 83 days. Innovaccer warned its provider portal might not be ready at launch, and CMS raised concerns that Zyter lacked adequate processes for answering providers. Vendors can receive a percentage of expenditures tied to care deemed wasteful and prevented, which CMS says is adjusted for accuracy. A licensed clinician must review every denial recommendation.

What the evidence does not show is whether the missing care was wasteful or necessary; the study authors say that answer may take years. The University of Minnesota's summary says the easing between quarters may reflect workflow problems being solved, clinicians learning the rules or both. That gap matters for operators and finance leaders, because it suggests part of the volume loss comes down to process, which a practice can manage.

The move: this week, identify which of your services and states fall under WISeR and stand up tracking of every request, its vendor, turnaround time and outcome. For the CFO and revenue cycle, that log quantifies volume at risk and supports appeals. For operations, it shows where front-desk and clinical staff lose hours chasing answers. For the Chief AI Officer, it is a direct read on how an AI-assisted review system behaves in practice. Patients gain a shorter, more predictable wait for the care their clinicians order.

You are an operations advisor to the COO and revenue cycle leaders of [your organization], a medical practice group that bills Medicare.

Context: Physicians Practice reports that Medicare's WISeR model, an AI-enabled prior authorization pilot, cut targeted services 15 to 20 percent in six states, and it lists 11 moves for practices. The model launched January 1, 2026, uses private technology companies to review requests, and runs through 2031 in Arizona, New Jersey, Ohio, Oklahoma, Texas and Washington. MedCity News describes a report drawn from lawsuit evidence that raises concerns about the experiment, including vendor delays and portal readiness. The federal government is testing whether AI can identify unnecessary care, speed prior authorization and reduce spending. The evidence does not show whether the missing care was wasteful or necessary.

Task: This week, determine which of our services and locations fall under WISeR, and design a simple tracking process for every WISeR request: service, state, reviewing vendor, date submitted, turnaround time, outcome, and any appeal.

Output: A draft workflow for the executive team, one page, with these sections: Scope (services and states in WISeR), Tracking Log Fields, Steps with Owners, Weekly Checks, Open Questions to Verify.

Use these details: [your states of operation], [your services that may be in scope], [your current monthly Medicare prior authorization volume], [the staff roles who submit prior authorizations], [your practice management system or EHR].

Guardrails: Use only the facts given here and the details I filled in. Cite Physicians Practice and MedCity News by name where you rely on them. Flag anything uncertain or that needs verifying against CMS guidance, especially the official list of services in scope. Do not request or include any patient data; the log should track requests by internal ID only. Nothing here is medical or legal advice. State clearly that this is a draft for the team to check.
