UnitedHealthcare is the 800-pound gorilla of health insurance — the largest health insurer in the country by revenue, with a provider network of over 1.3 million doctors and 6,500 hospitals. Their Medigap plans come with the AARP endorsement stamped on them, which carries weight with a lot of seniors even if it’s essentially a marketing partnership.
We reviewed UHC’s Medigap offerings across six cities to get a sense of their pricing and found a wide range. Plan G runs $142/month in Tempe, Arizona, but $327/month in Brooklyn. That’s the same plan from the same company — location matters that much.
What makes UHC interesting beyond the brand name is their wellness extras option. For a few extra dollars a month, you can add a fitness membership, a 24/7 nurse line, and discounts on dental, vision, and hearing. None of these are part of standard Medigap (which only covers what Original Medicare leaves behind), so this is UHC trying to differentiate in a market where every Plan G is otherwise identical.
David Chen enrolled his mother in a UHC Plan G with wellness extras last year. She uses the fitness benefit three times a week and has called the nurse line twice. For her, the extra $3/month was worth it. For someone who wouldn’t use those perks, it wouldn’t be. As always, Medicare costs and plan details change annually — verify everything at medicare.gov or with your state’s free SHIP program. Questions?

Medigap Plans Available
UnitedHealthcare offers plans A, B, G, K, L, and N — plus versions of most plans with optional wellness extras. Here’s a snapshot for a 66-year-old non-smoking woman in Philadelphia, PA:
| Plan | Minimum Monthly Premium | Wellness Extras |
|---|---|---|
| Plan A | $154.92 | Without |
| Plan A + wellness | $103.24 | With |
| Plan B | $164.29 | Without |

| Plan L + wellness | $115.59 | With |

| Plan N + wellness | $143.80 | With |
Premiums vary significantly by location. The same Plan G ranges from $142/month in Tempe, AZ to $326/month in Brooklyn, NY.
Plan Descriptions
Plans A and B: Good for members comfortable with more out-of-pocket expenses (no skilled nursing or foreign travel coverage) who want lower premiums.
Plan G: The most comprehensive option for new enrollees. Covers everything except the Part B deductible. After that one deductible, your covered costs are essentially $0 for the year.
Plan K: Starts at $66/month but covers only 50% of most costs until reaching the out-of-pocket maximum. After that, covered at 100%.
Plan L: 25% coinsurance with an out-of-pocket maximum. Better than Plan K; premiums are mid-range.
Plan N: Moderate premiums with copays of up to $20 for some office visits and $50 for ER visits. Good balance for healthy seniors.
Plans with wellness extras: Add a fitness membership, 24/7 nurse advice line, and discounts on hearing, dental, and vision to any of the above plans.

Our Verdict
UnitedHealthcare is an excellent Medigap provider for seniors who value the AARP endorsement, the nation’s largest provider network, and optional wellness extras. Their Plan G is the most comprehensive option for new enrollees.
The primary trade-off is premium cost — UHC tends to run above average in many markets. If your goal is the lowest possible premium for standardized coverage, Aetna or Cigna (with online discount) may serve you better.
For most seniors, UHC earns a strong recommendation — particularly for those already familiar with UnitedHealthcare’s Medicare Advantage products or with AARP membership.
