Aetna Medicare Part G: What the Plan Covers and How to Enroll

What Aetna Medicare Part G Covers

Aetna Medicare Part G is a Medigap plan that fills many of the gaps left by Original Medicare (Part A and Part B). It covers Medicare Part A coinsurance and hospital costs for an additional 365 days after Medicare benefits are used. Part G also pays for Part B coinsurance and copayments, the first three pints of blood, and skilled nursing facility coinsurance. Critically, it covers the Part A deductible in full. Unlike Part F, Part G does not cover the Part B deductible, so enrollees must pay that annually out of pocket before the plan pays its share for Part B services.

How Aetna Medicare Part G Differs from Other Medigap Plans

The main trade-off with Part G is the Part B deductible. Plan F covers that deductible, but Plan F is no longer available to people who became eligible for Medicare on or after January 1, 2020. Part G has become the closest alternative, offering identical core benefits minus that one deductible. Plan G typically carries a lower monthly premium than Plan F for this reason. Plan N is another option, but it requires copayments for some office visits and emergency room trips, which Part G does not. For many beneficiaries, Part G balances premium cost with predictable, first-dollar coverage for most Medicare-approved services.

Aetna Medicare Part G Costs and Pricing

Aetna sets Medigap Part G premiums based on factors like age, location, gender, and tobacco use. Pricing methods vary: community-rated plans charge the same premium regardless of age, while issue-age-rated plans base the premium on the age at enrollment. Attained-age-rated plans adjust premiums as you grow older. Because premiums are set by the insurer and state regulations, the exact monthly cost varies. Aetna may also offer discounts for paying annually, setting up automatic payment, or bundling with certain Medicare Advantage plans. The annual Part B deductible is a separate out-of-pocket cost that changes each year and is not covered by Part G.

Enrolling in Aetna Medicare Part G

The best time to enroll in any Medigap plan, including Part G, is during the six-month Medicare Supplement Open Enrollment Period. That period begins the first month you are both 65 or older and enrolled in Medicare Part B. During this window, Aetna cannot deny you coverage or charge higher premiums based on health history. Outside that period, enrollment depends on medical underwriting, and Aetna may decline coverage or impose waiting periods. To enroll, check plan availability in your ZIP code on Aetna's website or contact a licensed insurance agent. You can also call Aetna's Medicare helpline or visit your state's State Health Insurance Assistance Program (SHIP) office for unbiased guidance on comparing plans and signing up.

Where to Find More Information

Aetna's official plan documents, including the Summary of Benefits and the full policy wording, provide the most accurate details on covered services, limits, and exclusions. Beneficiaries should review these documents before enrolling. The Centers for Medicare & Medicaid Services (CMS) also publishes a Medigap comparison tool and standardized plan letter designations, so Part G benefits are the same regardless of which insurance company sells the policy. Verify that the specific Aetna plan you are considering is available in your county and confirm the insurer's current premium rates before making a decision.
