Aetna and Humana each sell HMO (Health Maintenance Organization) and PPO (Preferred Provider Organization) Medicare plans, which are the two most common types of Medicare Advantage plans. The Humana Choice PPO is particularly popular. 

Medicare Advantage plans include Medicare Part A and Part B health benefits along with additional coverage for things like dental, vision, prescription drugs and more.

Aetna and Humana both also offer Medicare Advantage Special Needs Plans (SNP), which include benefits that are tailored to the specific needs of someone with a particular health condition or financial situation. However, only Humana has Special Needs Plans for people with chronic health conditions. (Aetna Special Needs Plans are limited to those with dual eligibility, meaning they are eligible for both Medicare and Medicaid.)

Both companies sell Medicare Advantage plans nationwide. But Humana has the largest Medicare Advantage footprint of any other insurance company, with plans available in 89% of all counties in the U.S.

18% of all Medicare Advantage beneficiaries were members of a Humana Medicare plan in 2024. Aetna (CVS Health) plan members accounted for 11% of all Medicare Advantage enrollees in the same year.

The following example premiums are taken from the Medicare.gov plan finder tool in October 2023 for plan year 2024 and are not a complete list of plans available in each ZIP code.

The chart below shows which plans are available through each carrier. Again, please note that each of the following types of Medigap plans may or may not be available from either career in the ZIP code where you live. It’s helpful to get an online quote for Medigap plans or to call and speak with a licensed insurance agent who can help you compare plans. 

*Plan F and Plan C are not available to new Medicare beneficiaries who first became eligible for Medicare after January 1, 2020. If you became eligible for Medicare before that date, you may be allowed to apply for either plan if they're available where you live. If you already have Plan F or Plan C, you may keep your plan.
