Do you trust Medicare's new prior authorization pilots to effectively reduce waste without denying necessary care?
A new study shows that Medicare's WISeR pilot program, which requires prior authorization for certain services, led to a 15% drop in epidural steroid injections. The pilot, currently active in six states, affects millions of Original Medicare beneficiaries.
Why it matters
The program aims to curb potentially unnecessary care and fraud, yet it remains unclear if the reduction in services impacts patient health or simply prevents waste. This program could shape future Medicare policy regarding how and when prior approval is required for outpatient procedures.
A study using the Epic Cosmos database of 300 million records compared service usage in pilot states against others over two years before and six months after the program launch. While utilization dropped by 15% to 20%, it is still unknown if this shift affects patient clinical outcomes.
The players
Centers for Medicare & Medicaid Services
The federal agency that administers Medicare and launched the WISeR pilot to address medical service waste.
University of Minnesota
An academic institution whose researchers conducted the study using health record data.
Brown University
A research university that collaborated on the analysis of Medicare service utilization.
The details
The WISeR pilot requires prior approval or prepayment review for specific outpatient services within Original Medicare to target procedures with limited patient benefit. Researchers analyzed usage in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington to evaluate the impact of this increased administrative oversight. Providers who maintain high approval records may qualify for exemptions from these requirements, though the program does not extend to Medicare Advantage plans.
Timeline
Jan 1, 2026: The WISeR pilot program launched in six states.
Q1 2026: Epidural steroid injection use dropped 21%.
July 2026: The Senate voted against overturning the pilot.
Oct 26, 2026: Researchers published the study in JAMA.
Health Landscape
The WISeR pilot represents a significant shift toward stricter utilization management within the federal Original Medicare program. This model follows a broader trend of insurers increasing prior authorization requirements to contain rising healthcare expenditures.
If you are enrolled in Original Medicare in a pilot state, your doctor may now face additional review processes for certain outpatient procedures. It is worth discussing with your physician how these potential administrative delays might affect the timing of your planned care.
The takeaway
The WISeR pilot is changing how certain services are approved for Original Medicare patients in six states, leading to a marked decrease in specific procedures. Patients should track any changes in approval times for their scheduled outpatient care and discuss any concerns with their providers.
