How do I choose the best Medicare supplement (Medigap) plan?

Selecting Your Medigap Coverage: A Guide to Medicare Supplement Plans

Medicare Supplement Insurance (Medigap) helps pay the gaps in Original Medicare. Choosing the right plan requires understanding your options, costs, and enrollment timing.

Understanding Medigap Plan Options

  • Plan G: Most comprehensive available to new enrollees, covers everything except Part B deductible
  • Plan N: Lower premiums with small copays for some services
  • Plan F: Most comprehensive but only for those eligible before 2020
  • High-Deductible Options: Lower premiums with $2,800 deductible (2024)

What Medigap Covers

  • Part A hospital coinsurance and extra hospital days
  • Part B coinsurance or copayments
  • Blood (first 3 pints)
  • Part A hospice coinsurance
  • Skilled nursing facility coinsurance
  • Foreign travel emergencies (plans C-G, M, N)

Choosing the Right Plan

  • Consider Your Health: More comprehensive for chronic conditions
  • Budget Analysis: Balance premiums against potential out-of-pocket costs
  • Travel Needs: Foreign coverage if you travel internationally
  • Future Flexibility: Harder to change plans after initial enrollment

Critical Enrollment Timing

  • 6-month Open Enrollment when first getting Part B
  • Guaranteed acceptance regardless of health during this window
  • Medical underwriting required if applying later

Expert Tip:

  • Compare Plan G and Plan N carefully—Plan N’s lower premium often outweighs its small copays for healthy seniors.
