How to Compare Medigap Plans in 2025

An overview of the pros and cons of different Medigap plans.

1. Remember: Every Letter Is Standardized

Medigap benefits are set by law, not by the insurance company. A Plan G from Cigna must cover the exact same medical gaps as a Plan G from Anthem—the only real difference is the premium you pay.


2. Narrow the Alphabet to a Short List

Most people end up weighing just a handful of plans:

  • Plan G — broadest coverage now available to new beneficiaries.

  • Plan N — lower premiums, but small copays for office and ER visits.

  • High-Deductible Plan G (HD-G) — rock-bottom premiums; you shoulder a $2,800 deductible first.

  • Plans K & L — cost-sharing options with out-of-pocket limits. Start here, then rule plans out that cost more yet cover less (for example, Plans C, D, M, and B often get cut for exactly that reason).


3. Pull Quotes in Your ZIP Code

Identical coverage can cost $50–$100 a month more from one carrier to the next, and some states are simply pricier than others. New York and Connecticut, for instance, average $300–$500 monthly because they offer year-round open enrollment.


4. Look at the Carrier, Not Just the Plan

While benefits are standardized, carrier “extras” vary:

  • Rate-history & financial strength — steady premiums and solid AM Best grades are good signs.

  • Household or multi-policy discounts — can cut 5–12 % off the bill.

  • Customer service — some insurers handle claims faster and answer phones quicker.

These soft factors matter once the price gap between two quotes is small.


5. Check Your Timing

Outside your six-month Medigap Open Enrollment window (or other guaranteed-issue periods), insurers can ask health questions and charge more—or decline you entirely. If you’re healthy today, shop now; if you’re not, speak with an agent about any special rights you might have.


What we tell our friends and family: When in doubt, price Plan G first. If the premium is too high, look at Plan N or HD-G before sacrificing core benefits.
