Aetna Medicare is an HMO, PPO plan with a Medicare contract. Enrollment in our plans depends on contract renewal. Out-ofnetwork/non-contracted providers are under no obligation to treat Aetna members, except in emergency situations. Please call our customer service number or see your Evidence of Coverage for more information, including the cost-sharing that applies to out-of-network services. The formulary, provider and/ or pharmacy network may change at any time. You will receive notice when necessary. For mail-order, you can get prescription drugs shipped to your home through the network mail-order delivery program. Typically, mail-order drugs arrive within 10-14 days. You can call the number on your ID card if you do not receive your mail-order drugs within this timeframe. Members may have the option to sign-up for automated mail-order delivery. See Evidence of Coverage for a complete description of plan benefits, exclusions, limitations and conditions of coverage. Plan features and availability may vary by service area. Participating physicians, hospitals and other health care providers are independent contractors and are neither agents nor employees of Aetna. The availability of any particular provider cannot be guaranteed, and provider network composition is subject to change.
