UnitedHealthcare Has Wider Range of Medicare Advantage Plans
Both Aetna and UnitedHealthcare offer all three types of private Medicare insurance: Medicare Advantage (Medicare Part C) plans, Medicare Part D prescription drug plans and Medicare Supplement Insurance (also called Medigap) plans.
Aetna and UnitedHealthcare each sell the main types of Medicare Advantage plans, which typically include:
- HMO plans (Health Maintenance Organization)
- PPO plans (Preferred Provider Organization)
- POS plans (Point-of-Service)
- SNPs (Special Needs Plans)
However, the Aetna selection of Special Needs Plans only includes those for dual-eligible beneficiaries (those who are eligible for both Medicare and Medicaid). Aetna does not sell Special Needs Plans for people who have chronic conditions.
In addition to Dual-Eligible Special Needs Plans (D-SNP), UnitedHealthcare also sells Chronic Condition Special Needs Plans (C-SNP) and Institutional Special Needs Plans (I-SNP).
Chronic Condition Special Needs Plans are tailored specifically to beneficiaries with certain conditions, and UnitedHealthcare’s plans include options for those with diabetes, chronic heart failure and/or cardiovascular disorders.
Institutional Special Needs Plans are designed to meet the needs of beneficiaries under particular living circumstances. In the case of UnitedHealthcare, these include plans for those in assisted living homes and nursing homes.
As of the 2024 plan year, both Aetna and UnitedHealthcare sell Medicare Advantage plans in every state (and Washington D.C.), except Alaska.
UnitedHealthcare Has a Higher Average Medicare Star Ratings
Every year, Medicare evaluates plans on a 5-star rating scale. The Centers for Medicare and Medicaid Services (CMS) rates all Medicare Advantage and Medicare Part D plans – and the companies who provide them – across various quality metrics such as customer service, patient health outcomes and more.
For 2023, Aetna Medicare Advantage plans have an average star rating of out 3.72 out of 5 stars.1 Plans and carriers who receive four stars or higher are considered "highly rated" by Medicare.
UnitedHealthcare Medicare Advantage plans earned an average Star Rating of 3.86 out of 5 stars in 2023.1
Aetna vs. UHC: Medicare Supplement Plans
Medicare Part D plans provide coverage for prescription medications, which is not something typically covered by Medicare Part A or Part B (Original Medicare).
Aetna and UnitedHealthcare each offer several different Medicare Part D plans, and each company sells these plans in all 50 states and Washington D.C.
Each company offers a Part D plan with a low premium and high deductible, a plan with a high premium and low deductible and a plan with a mid-range premium and mid-range deductible to provide a plan option to consumers of every budget. (More on specific plan costs below.)
UnitedHealthcare utilizes many of the most popular pharmacies like Walgreens, along with OptumRx for mail-order prescriptions.
Aetna partners with CVS, Kroger, Costco, Safeway/Albertsons and other preferred pharmacies. Aetna OTC medications are available at these locations. Both carriers provide plenty of in-network pharmacy locations for a member’s needs.
Medicare Supplement Insurance (Medigap) plans help pay for many of the out-of-pocket costs tied to Medicare Part A and Part B, such as deductibles, copayments and coinsurance.
There are 10 standardized types of Medigap plans available in most states, each of which have benefits that are standardized by the federal government.
Aetna Medical Insurance offers seven different Medigap plans, while UnitedHealthcare offers nine different plans. Plan availability may vary where you live, however.
