New Medicare Prior Authorization Rules Coming in 2026

Medicare is preparing for some of its biggest changes in years. Starting in 2026, both Traditional Medicare and Medicare Advantage plans will operate under updated prior authorization rules. These changes are designed to increase transparency, speed up decisions, and test new methods for reducing unnecessary services.

Here’s a breakdown of what you can expect in 2026.

What Is Prior Authorization?

Prior authorization is the process where your healthcare provider gets approval from Medicare (or your Medicare Advantage plan) before delivering certain treatments, tests, or services. Without that approval, the service may not be covered.

Until now, prior authorization has mostly applied to Medicare Advantage plans, but beginning in 2026, Traditional Medicare will test prior authorization in select states.

Prior Authorization in Traditional Medicare: The 2026 Pilot Program

For the first time, Traditional Medicare will use prior authorization on a limited basis.

• Start Date: January 1, 2026

• States Included: Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington

• Services Impacted: 17 outpatient procedures, including some orthopedic, neurological, and skin-related treatments

• How It Works:

  • Providers can request approval before performing the service

  • If no request is submitted, Medicare may review the claim after the service is completed, which carries a risk of denial

• Decision Oversight: Technology and artificial intelligence will assist in reviews, but licensed clinicians will make final decisions

This pilot will run through December 31, 2031, and is part of Medicare’s effort to reduce wasteful or unnecessary services.

Medicare Advantage Prior Authorization Rules in 2026

Medicare Advantage plans already use prior authorization, but starting in 2026, they will face stricter requirements:

• Standard Requests must be reviewed within 7 calendar days

• Expedited Requests must be completed within 72 hours

• Approved Authorizations Stay Valid for the entire course of treatment, even if your provider leaves the network or you switch to another plan

• Public Reporting: Medicare Advantage plans must share data on how many prior authorization requests are approved, denied, or overturned on appeal

These rules build on changes beginning in 2025 and are meant to ensure patients don’t face unnecessary delays in care.

What the 2026 Changes Mean for You

• Traditional Medicare Members: If you live in one of the six pilot states, certain outpatient services may require prior authorization. If you’re outside those states, you won’t see any changes (at least for now).

• Medicare Advantage Members: You should benefit from faster, more consistent prior authorization processes, with rules that protect your access to approved care.

• Nationwide Impact: Even though the Traditional Medicare pilot is limited, it could expand in the future depending on its results.

Key Takeaways

• Traditional Medicare will test prior authorization starting in 2026 in six states.

• Medicare Advantage plans must follow faster timelines and greater transparency rules beginning in 2026.

• These changes aim to improve access to necessary care while reducing unnecessary costs.
