If you live in Arizona, New Jersey, Ohio, Oklahoma, Texas, or Washington and you have traditional Medicare, there’s a good chance you’ve already heard something about this. Maybe your doctor’s office called to say a procedure needs approval now. Maybe you’re waiting on a back injection that used to go through without a second thought. Or maybe you haven’t been affected yet but you’re worried, because you chose traditional Medicare specifically to avoid the prior authorization headaches that Medicare Advantage plans are famous for. That was a reasonable choice. It’s just that the rules changed in January 2026, and a lot of people are only now finding out.
Here’s what I tell people when they come in confused and frustrated: you’re not missing something obvious. This is genuinely new, and it caught a lot of providers off guard too. The program is called WISeR, which stands for Wasteful and Inappropriate Service Reduction. It launched January 1, 2026, under the Centers for Medicare and Medicaid Services, commonly called CMS. It’s a pilot program, meaning it’s being tested before any decision is made to expand it. The pilot runs through December 31, 2031, covering roughly 6.4 million traditional Medicare beneficiaries across those six states. And seven months in, it is not going smoothly.
A June 2026 report from Yahoo Finance and a July 2026 analysis from Rise Health both documented real, on-the-ground problems: AI-generated denials, long waits for doctors to reach a live reviewer, and patients sitting in pain while paperwork crawls through the system. One Arizona patient with severe back pain received two AI-generated denials before finally getting relief. That’s not an edge case. That’s a preview of what the system looks like when it doesn’t work the way it was designed to.
- WISeR launched January 1, 2026, covering 6.4 million traditional Medicare beneficiaries in 6 states.
- The pilot applies AI-assisted prior authorization to 17 outpatient procedures through December 31, 2031.
- As of mid-2026, documented cases include AI denials and long waits for peer-to-peer physician review.
- Beginning July 2026, CMS introduced "gold carding" to exempt high-performing physicians from prior authorization.
- 42 Democratic members of Congress formally challenged the pilot in a July 31, 2026 letter to CMS Administrator Dr. Mehmet Oz.
What Procedures Are Actually Affected
This is usually the first question people ask. Not every service requires prior authorization under WISeR. The pilot targets 17 specific outpatient procedures that CMS has flagged as potentially overused. The list includes some treatments that are quite common among older adults, which is part of why the backlash has been so sharp.
| Procedure Category | Examples Covered Under WISeR |
|---|---|
| Spine treatments | Epidural steroid injections, cervical fusion |
| Neurological | Deep brain stimulation for Parkinson’s disease |
| Joint care | Knee osteoarthritis treatments |
If you or someone you love is being treated for chronic back pain, Parkinson’s, or knee problems, you are in the group most likely to be affected. Routine preventive care, hospital stays, and most primary care visits are not part of this pilot. But for those 17 procedures, your doctor now needs to get approval before the service is performed, and in many cases that approval is being evaluated by an AI system first.
The AI Problem Nobody Told You About

Prior authorization itself isn’t new to Medicare. Medicare Advantage plans have used it for years, and beneficiaries in those plans have long complained about delays and denials. What’s different with WISeR is that traditional Medicare, which never had broad prior authorization requirements, is now using AI-assisted review for these decisions in pilot states.
The concern among physicians and patient advocates isn’t just that authorization is required. It’s that the AI is making initial decisions about medical necessity without seeing the full clinical picture. When a doctor disagrees with an AI denial, they can request what’s called a peer-to-peer review, meaning they get to talk directly to a human reviewer. But reports from June and July 2026 describe those waits as long and frustrating, and Healthcare Dive’s August 2026 coverage notes that provider concerns are mounting across the pilot states. Doctors are spending time on hold and paperwork instead of patients.
For someone in pain, waiting two rounds of denial before finally getting an epidural steroid injection isn’t an abstraction. It’s weeks of suffering.
Congress Is Pushing Back Hard
On July 31, 2026, 42 Democratic members of Congress sent a formal letter to CMS Administrator Dr. Mehmet Oz raising serious objections. Their letter described AI-fueled prior authorization as a threat that, in their words, “opens the door to further erosion of our Medicare system.” That’s strong language in a formal government communication, and it signals that this pilot is becoming a political flashpoint, not just a policy disagreement.
You might be wondering whether Congressional pressure will actually change anything. Honestly, it’s too early to say. CMS has shown some willingness to adjust the program. Starting in July 2026, the agency announced a “gold carding” policy: physicians who consistently get their authorization requests approved will eventually be exempted from the prior authorization requirement altogether. Some Medicare Advantage plans already use this approach. The idea is that doctors who demonstrate good judgment shouldn’t have to justify every procedure they order.
It’s a meaningful concession, but it doesn’t help you today if your doctor isn’t gold-carded yet, and it doesn’t address the fundamental question of whether this program should exist in traditional Medicare at all.
What You Can Do Right Now
If you’re in one of the six pilot states and you have a procedure coming up that might fall under the WISeR list, here’s what I’d tell a family member: talk to your doctor’s office before the appointment and ask whether prior authorization is required. Don’t assume. Ask explicitly.
If a prior authorization request is denied, you have appeal rights. You can request a redetermination, and your doctor can request a peer-to-peer review with a human clinician. These processes take time, which is genuinely frustrating, but they exist and they work more often than people expect. Document everything. Get denial notices in writing.
If you’re unsure about your rights or want help understanding a denial letter, call 1-800-MEDICARE or visit Medicare.gov. You can also contact your State Health Insurance Assistance Program, known as SHIP, for free one-on-one counseling. GoodRx’s July 2026 guide on Medicare prior authorization is also a helpful plain-English breakdown of the current rules.
This pilot has six more years to run, and the problems surfacing in its first seven months are exactly the kind of early data that can drive reform, if enough people speak up and Congress keeps the pressure on.
The WISeR pilot was designed to reduce unnecessary spending, and that’s a goal worth taking seriously. But a program that delays care for people with Parkinson’s disease or debilitating back pain isn’t saving money in any meaningful sense; it’s shifting costs onto patients in the form of suffering and lost time. The next year of this pilot, including whatever CMS does in response to Congressional pushback, will say a lot about what traditional Medicare looks like for the people who depend on it most.
