Major insurers are tightening the reins on Medicare Advantage. UnitedHealthcare and Aetna are shifting toward more restrictive plan types in 2027, limiting which providers enrollees can see. The moves come as government reimbursements fail to keep pace with rising medical costs, and enrollment is expected to dip by 6% to around 34 million people.
Major insurers are tightening the reins on Medicare Advantage. UnitedHealthcare and Aetna announced they'll be shifting toward more restrictive plan structures in 2027 — moving away from preferred provider organizations (PPOs), which allow members to see out-of-network doctors, and toward health maintenance organizations (HMOs), which limit coverage to a smaller, lower-cost provider network. Humana is also pulling back, reducing its county-level footprint from 85% to over 80% of U.S. counties.
The driving force? A widening gap between what the government pays insurers and what it actually costs to cover enrollees. Rising medical costs, higher drug prices, and increased utilization have squeezed margins, prompting insurers to exit less profitable markets and restructure their offerings.

Why it matters: For the tens of millions of seniors and people with disabilities relying on Medicare Advantage, these changes could mean fewer choices and more restricted access to their current doctors — a significant real-world impact as the 2027 plan year approaches.
