What is the best Medicare supplemental plan for seniors?


Editorial team Published on

Medicare Supplement (Medigap) Plan G is currently the best and most comprehensive choice for most new seniors, as it covers all out-of-pocket costs from Original Medicare except for the annual Part B deductible.

Because Medigap benefits are strictly standardized by the federal government, a Plan G or Plan N offers the exact same coverage no matter which private insurance company sells it. The best "company" comes down to pricing, rate stability, and customer service in your specific area.

Top-Rated Medigap Insurance Carriers

  • AARP / UnitedHealthcare: Widest nationwide availability and strong brand recognition, though monthly premiums can run higher than smaller competitors.
  • Mutual of Omaha: Highly trusted name with strong financial stability, though historical rate increases can be steeper in some regions.
  • State Farm: Frequently scores top marks for low consumer complaints and stable, slow price increases.
  • Bankers Fidelity / Medico: Often provide more budget-friendly, competitive monthly rates compared to larger household-name brands.

Most Popular Supplemental Plan Types

  • Plan G: Covers 100% of approved medical costs once you pay the small annual Part B deductible. It is ideal for complete peace of mind.
  • Plan N: Offers lower monthly premiums than Plan G in exchange for small copayments (up to $20 for doctor visits and $50 for emergency room visits) and no coverage for Part B excess charges.
  • High-Deductible Plan G: Features very low monthly premiums but requires you to pay out-of-pocket up to a higher deductible limit before coverage kicks in.
