Medicare Supplement Insurance

Both plans cover the major gaps in Original Medicare (Part A hospital copays, Part B coinsurance, excess charges, and more), but with a few differences. Plan G covers everything Plan N covers except Plan N has three cost-sharing items: up to $20 copay for office visits, up to $50 copay for emergency room visits (waived if admitted), and Plan N does not cover Part B excess charges. Plan G premiums are typically $30-$80 per month higher than Plan N, but Plan N's occasional copays usually don't offset that premium difference. Plan G is the most popular choice for people who want predictable costs and never want to see a bill; Plan N is better for healthy beneficiaries who see doctors infrequently and want lower monthly premium.

The best time is during your Medigap Open Enrollment Period — the 6 months beginning the first of the month you turn 65 AND are enrolled in Medicare Part B. During this window, carriers cannot decline you or charge higher premiums based on health — you get guaranteed-issue rights to any plan in your state. Outside this window, most states allow carriers to use medical underwriting, meaning pre-existing conditions can result in higher premiums or declines. Certain situations trigger additional guaranteed-issue rights: losing employer coverage, moving out of a Medicare Advantage plan's service area, or your Medicare Advantage plan terminating. Missing the initial window without a trigger makes later enrollment harder and more expensive.

Yes, but switching typically requires medical underwriting — the new carrier can decline you or charge higher premiums based on your health. If approved, there's typically no waiting period for pre-existing conditions if you're switching from another Medigap plan with continuous coverage. Certain states (Connecticut, Maine, Massachusetts, New York, California, Missouri, Washington, Oregon) have 'birthday rules' or annual guaranteed-issue windows that let you switch to equal-or-lesser coverage without underwriting. Switching makes sense when a new carrier offers significantly lower premium for the same plan letter — policies are standardized, so Plan G from Carrier A covers the same as Plan G from Carrier B. Rate shopping every 2-3 years often saves $30-$100 per month.

No — Medicare Supplement plans do not cover prescription drugs. You need a separate Medicare Part D plan for prescription coverage. This is different from Medicare Advantage plans (Part C), which typically bundle Medicare A, B, and D together. The separation means with Original Medicare plus a Medigap plan, you'll have three cards: Medicare (red, white, blue), Medicare Supplement, and Part D. Part D plans have their own premiums ($0-$100+ per month depending on coverage level), deductibles, and formularies. Choosing a Part D plan is a separate decision and should be based on your specific medications — using the Medicare.gov plan finder with your prescription list is the best way to compare.

Carriers use one of three pricing methods: community-rated (same premium for all ages), issue-age-rated (premium based on age when you enrolled, doesn't increase due to age), or attained-age-rated (premium increases as you age). Most carriers use attained-age pricing, which starts lowest at age 65 but increases each year. Issue-age policies often cost more at 65 but can be cheaper by age 80. Within each pricing method, premiums are also based on tobacco use, household discounts (5-14% for spouses both enrolled), and carrier's overall claims experience. Premium increases also happen annually due to medical inflation across all policyholders, typically 3-8% per year regardless of pricing method.
