For 2027, UnitedHealthcare is dropping 34 Medicare Advantage PPO plans, so UnitedHealthcare PPO members should first check that their plan is continuing; if it is, compare its in-network and out-of-network costs for 2027.
With a UnitedHealthcare Medicare Advantage PPO, in-network care costs the least, and care from out-of-network providers who accept Medicare is covered at a higher cost, typically with no referrals needed. People who travel, live in more than one state, or want to stay with certain specialists often like PPOs for that flexibility.
For 2027, PPOs are where large insurers are cutting most: UnitedHealthcare 34, Humana 37, Aetna 20 and HCSC 48. This guide explains how UnitedHealthcare PPOs work and what to check. See UHC Medicare Advantage plans and UnitedHealthcare Medicare Advantage plans.
