Medicare Advantage 2027: how payer changes affect your clinic
CMS finalized the 2027 Medicare Advantage rule. Star ratings, network adequacy, and prior auth requirements are all changing. Here is what matters for your contracts.
What CMS finalized on April 2, 2026
The CY2027 Medicare Advantage and Part D Final Rule includes significant changes to how MA plans are rated, how they build provider networks, and how they handle prior authorization. These changes affect every clinic that contracts with Medicare Advantage plans.
The rule removes 11 star rating measures the agency viewed as either administrative or low-variation, and adds one new Part C behavioral health measure (Depression Screening and Follow-Up) starting with the 2027 measurement year and 2029 Star Ratings. For your practice, this means MA plans will be adjusting their priorities, and those priorities will flow down to their provider contracts and performance expectations.
Star ratings overhaul
CMS finalized removal of 11 measures from the star ratings system (down from 12 in the proposed rule — the Part C Diabetes Care – Eye Exam measure was retained after stakeholder feedback) and added one new Part C Depression Screening and Follow-Up measure. MA plans live and die by their star ratings because ratings determine their bonus payments from CMS.
When plans change their star rating focus areas, they change what they demand from providers. Expect your MA contracts to include new quality metrics aligned with the updated star measures. Plans that drop from 4 to 3.5 stars lose tens of millions in bonuses, so they will push hard on providers to hit the new targets.
Network adequacy changes
The final rule tightens network adequacy standards, meaning MA plans must ensure sufficient provider access in terms of both geographic distance and appointment wait times. This could benefit your practice if you are in an underserved area, as plans may need to add providers and may offer better contract terms to fill gaps.
If you are currently out-of-network with MA plans, this may be an opportunity to negotiate. Plans that are failing adequacy requirements in your area need providers, and you have leverage.
Prior authorization requirements
The rule requires MA plans to align their prior authorization requirements more closely with traditional Medicare. Services that do not require prior auth under fee-for-service Medicare should not require prior auth under MA plans, with limited exceptions.
This could meaningfully reduce your administrative burden. Track which MA plans currently require prior auth for services that fee-for-service Medicare does not. Those auths should go away in 2027. If they do not, you have a compliance complaint to file.
Impact on your MA contracts
Review your MA contracts that come up for renewal in 2026-2027. The changing rules give you leverage in negotiations. Plans need to meet new adequacy standards, and they need providers who can help them hit new quality targets.
If your practice performs well on the new quality measures (health equity, behavioral health, patient experience), highlight that in contract negotiations. Plans will pay more for providers who help them maintain their star ratings.
What to do with your payer mix data
Pull your MA payer mix data. What percentage of your revenue comes from Medicare Advantage versus fee-for-service Medicare? Which specific MA plans do you contract with, and what are their current star ratings?
Plans that are at risk of dropping star ratings will be the most aggressive about pushing new quality requirements onto providers. Plans that are comfortably at 4+ stars may be more flexible. Knowing where your plans stand helps you anticipate contract changes.
What to do now
Pull your revenue breakdown by MA plan to understand which plans represent the most revenue.
Review the star ratings of your top MA plans to anticipate which will push hardest on new quality measures.
Identify MA prior auth requirements that conflict with fee-for-service Medicare and prepare to challenge them.
Evaluate whether network adequacy changes create an opportunity to negotiate better MA contract rates.
Update your quality tracking to align with the new star rating measures CMS has adopted.
Schedule contract reviews for any MA agreements coming up for renewal in 2026-2027.
