Medicare Part A and Part B Eligibility with Aetna
Eligibility for Medicare Part A and Part B is determined by federal rules, not by Aetna, yet Aetna builds its Medicare plans on top of this foundational coverage. Most people become eligible for premium-free Part A at age 65 if they or a spouse paid Medicare taxes for at least 10 years, while Part B typically requires a monthly premium. Aetna Medicare Advantage and Medigap plans require you to first be enrolled in both Part A and Part B to remain eligible for their benefits.
Medicare Advantage Eligibility and Plan Specifics
Medicare Advantage eligibility for Aetna plans follows the same basic rules as original Medicare, with the added requirement that you must live within a plan’s service area and not be in a treatment situation that conflicts with plan rules. These plans bundle Part A, Part B, and usually Part D, and may include extra benefits like dental or vision. If you have End-Stage Renal Disease or ALS, you generally cannot enroll in most Medicare Advantage plans, including many Aetna options, unless a plan specifically covers these conditions in your area.
Medigap Eligibility and How It Works with Aetna
Medigap, or Medicare Supplement, eligibility centers on your age at the time you first buy a plan and your continuous creditable coverage. Aetna Medigap plans are available in many states, and underwriting is often community-rated or issue-age-rated, which can affect your premiums. You generally cannot drop an existing Medigap policy if you switch to a Medicare Advantage plan, and some Aetna Medigap options may not be available in every state or county.
Enrollment Timelines and When You Can Join
Your initial enrollment period for Aetna Medicare Advantage or Medigap begins three months before your 65th birthday and lasts through the three months after that birthday. Outside this window, you may need to wait for the General Enrollment Period or qualify for a Special Enrollment Period, for example if you left work-based coverage. If you have End-Stage Renal Disease or certain disabilities, you might still qualify during limited windows, depending on the state and product.
Prescription Drug Coverage and Plan Rules
When you choose an Aetna Medicare Advantage plan with prescription drug coverage, you join a Medicare Part D plan that must follow federal rules for covered drugs, prior authorization, and step therapy. Aetna formularies vary by region, so it is important to check whether your current medications are covered and whether your preferred pharmacies are in network. Out-of-pocket maximums for drugs and medical care combine under the Medicare Advantage plan, which can help cap your spending for the year.

FAQ
Reader questions
Can I enroll in an Aetna Medicare plan if I am under 65?
You may qualify if you have been receiving Social Security Disability Insurance for 24 months or have End-Stage Renal Disease or ALS, and you must also meet U.S. citizenship or lawful presence and Aetna service area requirements.
What happens if I miss my initial enrollment period for Aetna Medicare?
You can enroll during the General Enrollment Period from January 1 through March 31 each year, with coverage starting July 1, but you may face late enrollment penalties unless you have other credible coverage.
Does Aetna Medicare cover care outside my home state?
Most Aetna Medicare Advantage plans are regional, so coverage and provider networks are generally limited to specific service areas; you should verify benefits and travel rules directly with Aetna if you plan to be away from home.
Can I switch from Aetna Medicare Advantage to Medigap later?
Switching from Medicare Advantage to Medigap can be difficult because you must first leave the Advantage plan and rejoin original Medicare, and Medigap underwriting may result in higher premiums or denial if you have health conditions.
