Aetna Medicare Supplement Plan G is Medigap insurance that helps with specified Original Medicare costs. It is not Medicare Advantage, and there is no Medicare Part G. You retain Part A and Part B and pay a separate supplement premium.

What standard Plan G does and does not pay
Standard Plan G includes specified Part A and Part B cost-sharing benefits, including the Part A deductible and qualifying Part B coinsurance. It does not pay the annual Part B deductible. It also includes limited foreign-travel emergency coverage under the policy's conditions.
Routine dental care, ordinary hearing aids and long-term custodial care are not automatically included. Newly sold Medigap policies do not include Part D coverage. Separate products or discounts should not be presented as standardized Plan G benefits.

| Issuing insurer and state | Aetna-branded offerings and availability vary. |

| Enrollment rights | Underwriting may apply outside a protected opportunity. |
Providers and policy version
Standard Medigap generally works with providers accepting Original Medicare rather than an Aetna Medicare Advantage network. Check any policy-specific restrictions. A high-deductible Plan G, if offered, requires meeting its separate deductible before eligible supplement payments begin.
Before applying or switching
Use Aetna's official Medicare Supplement state selection and current Outline of Coverage. The federal Medigap Open Enrollment Period generally begins when you are at least 65 and enrolled in Part B; other state or guaranteed-issue rights may apply.
Keep existing coverage until the new policy is approved and dates are coordinated. Compare equivalent policy versions and total annual expenses rather than choosing from an unverified review or a premium quoted for another person.
