Medicare Supplement (Medigap) Plans in Oregon—Fill the Gaps with Confidence

What Are Medicare Supplement Plans (Medigap) and How Do They Work?
Medicare Supplement (Medigap) policies are add-on insurance from private companies that help pay the deductibles, copays, and coinsurance that Original Medicare Parts A and B don’t cover. Medigap plans work alongside Medicare—not instead of it—giving you more predictable health costs and the freedom to see any provider nationwide who accepts Medicare. You cannot have Medigap and a Medicare Advantage plan at the same time.
Standardized Plans—A, G, N & More: What’s Available in Oregon?
Medigap plans are standardized, meaning every Plan G or Plan N offers the same benefits, no matter which insurer you choose.
- Plan G is the most comprehensive plan for new Medicare enrollees (covers everything except the Part B deductible).
- Plan N has lower premiums and small copays, making it a popular alternative for budget-conscious seniors.
- Other plans (like A, K, L, M) are also available, each with unique cost and coverage features.

Enrollment, Eligibility & Oregon’s Birthday Rule
The best time to enroll in a Medigap plan is during your Open Enrollment Period—six months after your Part B starts at age 65—when you can get any plan, regardless of health. Oregon residents also benefit from the Medigap “Birthday Rule,” allowing you to switch plans each year around your birthday without new health questions. This means more flexibility and options, even after your initial enrollment window.
What Do Medigap Plans Cost in Oregon?
Medigap premiums depend on factors like age, plan letter, tobacco use, and location. While prices change, a 65-year-old in Oregon might pay about $120–$150/month for Plan G, with Plan N often lower. You pay more up front than with a $0 Medicare Advantage plan, but Medigap offers peace of mind: no huge surprise bills at time of care, and broad provider choice. There’s never an extra fee for using a broker—your price is the same, but you get expert help.
