How to Choose the Best Medicare Supplement Plan
Beyond price and plan letter, consider how rates change over time, whether your insurer will exist in 20 years and how they treat customers filing claims to find the best medicare supplement company in Oregon.
- 1Assess Your Health Care Needs
Do you travel frequently? How often do you see doctors? More coverage costs more monthly but saves you money when you need care. If you have ongoing medical conditions requiring regular treatment, higher monthly premiums often cost less overall through lower out-of-pocket costs.
- 2Compare Plan Types
Plan G offers the most coverage for new Medicare beneficiaries. Plan N provides similar benefits with lower premiums plus modest copays ($20 for doctor visits, $50 for emergency room). Plan F, available only if you enrolled in Medicare before 2020, covers all out-of-pocket costs. Plans K and L cost less monthly but require you to pay a percentage of costs until you hit an annual limit. Plans A, C and D cover basics with varying benefit levels. Plans B and M fill specific gaps between basic and comprehensive coverage.
- 3Get Quotes From Multiple Providers
Get quotes from at least three companies to ensure competitive rates. Insurers charge different rates for identical coverage.
- 4Check Pricing Style
Three pricing methods exist: Issue Age (locked at your enrollment age), Attained Age (rises as you age) and Community-Rated (same for everyone). Issue Age and Community-Rated plans save you money long-term.
- 5Check Company Ratings
Check AM Best ratings for financial stability and customer satisfaction scores for service quality. Cheaper premiums aren't worth it if your insurer delays claims or provides poor service.
- 6Enroll During Open Enrollment
Enroll during the six-month window starting when you turn 65 and sign up for Medicare Part B. You're guaranteed acceptance regardless of health conditions. Wait longer, and insurers may charge more or deny coverage.

Medicare Supplement Plans in Oregon: FAQ
Here are common questions about Medigap coverage in Oregon.
When is Medicare Supplement open enrollment in Oregon?
Medicare Supplement open enrollment in Oregon begins when you turn 65 and enroll in Medicare Part B. This six-month window guarantees coverage regardless of health conditions. You can buy a Medicare Supplement plan anytime, but insurers can deny coverage or charge higher rates outside this period.
What are the most popular Medicare Supplement plans?
Plan G, Plan F and Plan N are the most popular Medicare Supplement plans. Plan G offers comprehensive coverage with predictable out-of-pocket costs. Plan F provides the most complete coverage but is available only to those eligible before 2020. Plan N offers lower premiums with modest copayments ($20 for doctor visits, $50 for emergency room). Learn more about Medicare coverage.
Do you have to renew Medigap plans every year?
No. Medicare Supplement plans automatically renew as long as you pay premiums on time. Your coverage continues indefinitely without annual enrollment periods, unlike Medicare Advantage plans that require yearly review during open enrollment.
What's the difference between Medicare Supplement and Medicare Advantage?
Medicare Supplement plans work with Original Medicare to cover out-of-pocket costs like deductibles and copayments. Medicare Advantage plans replace Original Medicare entirely, providing an all-in-one alternative with different networks, costs and coverage rules. Supplement plans offer more provider flexibility. Advantage plans often include extras like dental and vision coverage.
Our Methodology
MoneyGeek collected Oregon Medicare Supplement data for 65-year-olds and 75-year-olds using Medicare.gov's plan browsing tool. Unless otherwise noted, this article references quotes for 65-year-olds.
We scored Oregon Medigap companies across three categories to create a weighted score out of 5:
- Affordability (50%): Lower monthly premiums earn higher scores.
- Pricing style (20%): We scored pricing methods based on long-term stability and fairness: Community Pricing (1.0), Issue-Age Pricing (0.8) and Attained-Age Pricing (0.6). A community-rated plan with slightly higher costs can outscore a cheaper attained-age plan because community-rated premiums stay stable as you age.
- Plan availability (30%): Insurers offering more plan types score higher. We weighted popular plans (G, F and N) more heavily in scoring.
