For decades, Traditional Medicare has been the poster child for transparent and straightforward healthcare—delivering care with the least amount of bureaucratic hoop-jumping. If you’re a provider or patient accustomed to that streamlined experience, brace yourself: January 2026 marks a historic change. The Centers for Medicare & Medicaid Services (CMS) will pilot a system that uses artificial intelligence (AI) and machine learning to process prior authorization requests across six states.
This program, called the Wasteful and Inappropriate Service Reduction (WISeR) Model, targets 17 medical services and procedures most at risk for fraud, waste, or abuse—from nerve stimulators to incontinence devices to orthopaedic surgeries. If you’re in Arizona, New Jersey, Ohio, Oklahoma, Texas, or Washington, expect to be in the vanguard of the government’s experiment in smarter healthcare oversight.
What Are the Risks and Rewards of Medicare’s New AI Authorization Model?
The Big Promise: CMS says AI will dramatically streamline paperwork, reduce fraud, and make prior authorizations faster and more predictable. Historical pilots (like the one run by Blue Cross Blue Shield in Massachusetts) showed that AI can automate as much as 75% of manual work, processing most requests in real time.
Clinicians Still Rule: Even as robots scan the piles of paperwork, it’s licensed human clinicians who make the final call—AI might flag a questionable request, but only a qualified doctor can actually deny or approve your care. For providers, your documentation and medical rationale remain essential.
The Financial Angle: Here’s where things get sticky. Technology partners (including some Medicare Advantage payors) are compensated with a share of the “averted expenses”—the savings produced from denied or avoided unnecessary care. Critics argue this creates a direct incentive to deny more requests, potentially leading to delays or inappropriate barriers to care.
Growing Criticism: Both left- and right-leaning health advocates are skeptical. Some warn that adding “untested AI” to a process already managed by Medicare Administrative Contractors might only tangle the system further. Others argue that prior authorizations—long the bane of Medicare Advantage—are now being imported into Original Medicare, erasing one of its key benefits: ease of access and simplicity.
What Services Will Be Impacted?
Not all medical services get swept up in this sea change. WISeR zeroes in on 17 procedures and therapies most associated with fraud or unnecessary claims, including:
Electrical and phrenic nerve stimulators
Cervical spinal fusions
Knee arthroscopy for osteoarthritis
Incontinence devices
Epidural steroid injections
Skin and tissue substitutes for chronic wounds
These are outpatient services—not emergency care or inpatient surgeries—so urgent medical interventions won’t be slowed down by this new process.
How Will This Affect Patients and Providers?
Providers in pilot states must either request prior authorization or face post-payment medical review. CMS is also testing a “gold card” approach: providers with more than 90% of approvals may be exempted from future prior authorization requirements.
For patients, this means that some previously simple procedures will now require a pre-service approval process. CMS hopes this will redirect patients toward more clinically appropriate pathways if requests are denied.
The Road Ahead
If WISeR performs well, it could expand nationwide and to more types of services—including inpatient care. On the flip side, if critics are right, it could mean that Medicare’s historic simplicity gives way to a layer of algorithm-driven gatekeeping—potentially trading fraud prevention for greater risk of bureaucratic delay.
As always, the real test will be how AI and human clinicians work together—and whether Medicare can strike the right balance between oversight and patient-centered care. January 2026 may be the moment Medicare enters the era of machine intelligence or stumbles into a new chapter of administrative gridlock.
