Plan G vs. Plan N: compare the tradeoffs, not just the premium

Plan G and Plan N are standardized Medicare Supplement options. The benefits for each letter are standardized, but premiums, discounts, underwriting, and rate history vary by insurance company.

What both plans have in common

Both work with Original Medicare and generally allow access to providers nationwide who accept Medicare. Neither includes outpatient prescription drug coverage, so a separate Part D plan is usually considered.

  • Original Medicare remains primary
  • Standardized benefits by plan letter
  • No built-in outpatient drug coverage
  • Separate monthly premium

Where Plan N asks you to share more

Plan N may have a lower premium but can require certain office-visit and emergency-room copays. It also does not cover Part B excess charges. Plan G generally covers the other standardized gaps described above, but it does not pay the Medicare Part B deductible.

  • Compare premium savings
  • Estimate office and emergency visits
  • Understand Part B excess charges
  • Check state and provider billing rules

Look beyond today's rate

A low introductory premium can change. Ask about attained-age, issue-age, or community rating where applicable; household discounts; rate history; and how the company handles future increases. No agent can guarantee future premiums.

  • Current premium
  • Household discount rules
  • Rate-change history
  • Financial strength and service

Enrollment rights can decide the timing

Your federal Medigap Open Enrollment Period and other guaranteed-issue rights may let you buy without medical underwriting. Outside those rights, a carrier may ask health questions and decline the application.
