Doctors and the Aetna network

Doctors and the Aetna network

Keeping their current doctors is important to Trust members. And the county a member resides in will determine whether they have the preferred provider organization (PPO) plan or the extended service area (ESA) plan. With both plans, members can use the doctors in or out of their Aetna network. However, there are differences. 


  • Aetna Medicare Advantage PPO plan
    Members in the PPO plan can see any provider who participates with Medicare and accepts the Aetna plan. When they use providers in Aetna’s network, they’ll pay less out of pocket. Members can also use out-of-network providers, but they’ll pay more.
  • Aetna Medicare Advantage PPO ESA plan
    Members in the PPO ESA plan can see any provider who participates with Medicare and is willing to treat them, even if they are not in our network. Regardless of whether the provider is in or out of the network, members will pay the same cost-share amount.
  • Great news! All ESA and PPO service areas will remain the same for 2022.
