UnitedHealthcare and Humana are two of the biggest names in Medicare Advantage, and if you’ve started shopping for a plan, there’s a good chance both have shown up in your mailbox already. UnitedHealthcare’s plans are often sold under the AARP brand, which adds a layer of trust for a lot of shoppers — but a familiar name isn’t the same as the right plan for you. Here’s how the two actually compare in 2026.
The Quick Answer
- AARP/UnitedHealthcare tends to win on network size and CMS quality ratings — it’s the largest Medicare Advantage carrier in the country, with the broadest provider network and consistently strong star ratings.
- Humana tends to win on price — lower average premiums, competitive drug costs, and many plans include a Part B Giveback benefit that puts money back in your pocket every month.
Both carriers offer HMO and PPO options, $0-premium plans in many areas, and bundled extras like dental, vision, and hearing. Which one is «better» really comes down to your ZIP code, your doctors, and what you value more: network reach or monthly cost.
AARP / UnitedHealthcare Medicare Advantage
UnitedHealthcare is the largest health insurer in the United States, and many of its Medicare Advantage plans carry AARP branding through a licensing agreement — AARP doesn’t sell insurance itself, but it endorses and co-brands certain UnitedHealthcare plans.
What stands out about UnitedHealthcare in 2026:
- An average CMS star rating around 4.1–4.2, among the highest of the major national carriers
- One of the largest Medicare Advantage provider networks in the country, with well over a million in-network doctors and specialists
- Available in all 50 states, with $0-premium HMO plans in most markets
- Dental, vision, and hearing coverage bundled into most plans
- Strong marks for preventive care and screening programs
Where it tends to fall short: customer satisfaction surveys are inconsistent by region, and because it’s such a large carrier, the experience can vary noticeably depending on which state and plan you’re in.
Humana Medicare Advantage
Humana has built its Medicare Advantage business specifically around affordability and senior-focused extras, and it shows in the plan design.
What stands out about Humana in 2026:
- Lower average premiums than UnitedHealthcare in most markets, with many $0-premium options
- A Part B Giveback benefit on many plans — the plan covers part of your Part B premium, which effectively lowers what gets deducted from your Social Security check
- Competitive prescription drug pricing on many formularies
- Generous over-the-counter (OTC) allowances, in some cases up to $250 per quarter, plus SilverSneakers gym access on many plans
- Available in roughly 85% of U.S. counties
Where it tends to fall short: Humana’s average CMS star ratings have historically trailed UnitedHealthcare’s, particularly on customer experience and complaint metrics, though this varies significantly by specific plan and state — some Humana plans do earn 4 and 4.5 stars.
Side-by-Side Comparison
| AARP / UnitedHealthcare | Humana | |
|---|---|---|
| Average CMS star rating (2026) | ~4.1–4.2 | Varies widely by plan, often lower on average |

| County availability | All 50 states | About 85% of U.S. counties |

| Dental/vision/hearing | Included on most plans | Included on most plans |
| Best known for | Brand trust (AARP), network size, quality ratings | Value pricing, giveback benefits, senior-focused perks |
Pros and Cons
AARP / UnitedHealthcare — Pros:
- Largest network of doctors and hospitals among major carriers
- Consistently high CMS star ratings
- Available nationwide, including rural counties
AARP / UnitedHealthcare — Cons:
- Customer satisfaction scores can vary a lot by state
- Being the biggest carrier doesn’t always mean the cheapest plan in your county
Humana — Pros:
- Often the lower-cost option, especially with the Part B Giveback
- Strong OTC and fitness benefits
- Competitive drug pricing on many formularies
Humana — Cons:
- Not available in every county
- Historically lower average star ratings, though individual plans vary
Which One Should You Choose?
There’s no universal winner — it genuinely depends on three things: your county, your doctors, and your budget priorities.
- Lean toward UnitedHealthcare/AARP if: you want the widest possible choice of doctors and hospitals, you travel between states, or you specifically value a plan with consistently strong CMS quality ratings.
- Lean toward Humana if: lowering your monthly costs matters most, you’d benefit from a Part B Giveback, or you want stronger over-the-counter and wellness perks bundled in.
The single most important step, regardless of which carrier you’re leaning toward, is checking which specific plans are available in your county — both carriers offer dozens of different plans nationwide, and star ratings, premiums, and networks can differ enormously from one plan ID to another, even within the same company.
How to Compare Plans in Your Area
- Use the official Medicare Plan Finder at Medicare.gov and enter your ZIP code.
- Make a list of your current doctors and check whether each one is in-network for the specific plan you’re considering — not just «the carrier,» but that exact plan ID.
- Check your prescriptions against the plan’s drug formulary and tier pricing.
- Compare the plan’s star rating, not just the carrier’s average — individual plans can differ from the company-wide number.
- Confirm the annual out-of-pocket maximum and any Part B Giveback amount before enrolling.
Frequently Asked Questions
Is AARP the same company as UnitedHealthcare? No. AARP is a nonprofit membership organization that licenses its name and endorses certain UnitedHealthcare Medicare plans in exchange for royalty payments. UnitedHealthcare is the actual insurance carrier underwriting and administering the coverage.
Does Humana offer AARP-branded plans? No. AARP’s Medicare co-branding agreement is specifically with UnitedHealthcare, not Humana.
Which carrier has better customer service? It varies by state and by specific plan. Checking recent CMS star ratings and plan-specific reviews for your area is more reliable than a blanket comparison between the two companies.
Can I switch between UnitedHealthcare and Humana later? Yes, generally during the Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31), as long as you’re within an eligible enrollment window.
Is a Part B Giveback worth choosing a plan for? It can meaningfully lower your monthly costs, but weigh it against network access and your specific doctors and prescriptions — a small monthly giveback isn’t worth much if your preferred specialist is out of network.
Bottom Line
AARP/UnitedHealthcare and Humana approach Medicare Advantage from two different angles: UnitedHealthcare leans on scale, network size, and quality ratings, while Humana leans on affordability and senior-focused perks. Neither is objectively «better» — the right choice depends on which specific plan is available where you live, which doctors you need to keep, and whether you’d rather optimize for lower monthly costs or broader access.
Before enrolling in either, compare the exact plans available in your ZIP code using the official Medicare Plan Finder, or speak with a licensed insurance agent or your local State Health Insurance Assistance Program (SHIP) for free, unbiased guidance.
