Moda Health
Average Plan G Rate
$185Plan Types
A, F, G, N
- pros
Most affordable Plan G rates ($185/month)
Offers four popular plan types (A, F, G, N)
Strong financial stability
consNo Plans B, C, D, K, L or M
No cost-sharing plans (K, L)
Moda Health ranks first for Plan G coverage in Oregon at $185 per month, $39 below the state average of $224. In MoneyGeek's Oregon rate data, Moda Health's cost advantage held across all four plan types it offers: A, F, G and N, with premiums ranging from $49 to $356 per month for new enrollees. Moda Health also includes vision and dental benefits alongside Medigap coverage.
Moda Health's four-plan lineup leaves gaps for seniors who want broader options. Plans K and L, which cap out-of-pocket exposure at a fixed annual limit, are not available, nor are Plans B, C, D or M. Seniors who want every standardized plan option available before deciding may find United American's nine-plan roster a better fit.

USAA
Average Plan G Rate
$188Plan Types
A, F, G, N
- pros
$197 per month for Plan F, competitive among Oregon providers
Additional benefits for military members
consNo Plans B, C, D, K, L or M
USAA offers Medicare Supplement coverage in Oregon exclusively to active duty members, veterans and their families. It holds the lowest Plan F rate in Oregon at $197 per month across four plan types: A, F, G and N. Eligibility is limited to military members and their families, which rules out most Oregon seniors.
USAA's military-only eligibility disqualifies most Oregon seniors. For those who qualify, its four-plan lineup still excludes Plans B, C, D, K, L and M. Oregon seniors who want Plan K or Plan L to cap annual out-of-pocket costs will find both at AARP: Plan K at $66 per month and Plan L at $118 per month.

Everence
Average Plan G Rate
$195Plan Types
A, F, G, L, N
- pros
Best Plan L and N prices at $118 a month and $128 monthly, respectively
Stable financial performance
Offers faith-based community support programs
consDoesn't offer Plan K
Everence operates in Oregon's Medicare Supplement market with a faith-based model, offering the lowest rates for Plans L and N at $118 and $128 per month. Those rates are $21 and $37 below competitors per MoneyGeek's analysis. Everence offers five plan types: A, F, G, L and N, with monthly premiums ranging from $118 to $347.
Everence's faith-based model appeals to some seniors but not others. Its five-plan lineup omits Plans B, C, D and K entirely. Oregon seniors who want Plan K's 50% cost-sharing structure or any of the mid-tier plans should compare Humana, which offers eight plan types, including both K and L.

United American
Average Plan G Rate
$214Plan Types
A, B, C, D, F, G, K, L, N
- pros
Excellent Plan A and C rates in the state.
A (Excellent) rating from AM Best
consHigher Plan G rate than most Oregon competitors
United American ranks first in Oregon for Plan A at $108 monthly, saving enrollees $97 compared to the state average and leads Plan C pricing at $222 a month with $56 in monthly savings. Nine plan types are available: A, B, C, D, F, G, K, L and N, with premiums ranging from $42 to $374 depending on coverage level. United American's A (Excellent) AM Best rating reflects strong long-term financial stability.
United American's Plan G rate of $214 monthly is the highest in Oregon's Plan G table. Seniors whose primary goal is the lowest Plan G premium will pay $29 more per month here than at Moda Health ($185), adding up to $348 per year for identical standardized benefits. If Plan G is your target and price is the deciding factor, start with Moda Health or State Farm before comparing further.

Humana

A, B, C, F, G, K, L, N
- pros
Plan B priced competitively in Oregon ($208 a month)
Wide range of additional benefits
AM Best A rating
consNo high-deductible Plan G
Humana offers Oregon seniors eight Medigap plan types: A, B, C, F, G, K, L and N. It holds the lowest rate for Plan B in Oregon at $208 per month, $42 below the state average. Monthly premiums range from $50 to $510, depending on coverage level. Humana also offers wellness programs covering routine care and preventive services.
Humana's Plan G rate of $344 per month is the highest in Oregon among providers MoneyGeek analyzed, running $159 more per month than Moda Health's $185. Over a year, that difference totals $1,908 for the same standardized Plan G benefits. Oregon seniors comparing Plan G will find lower pricing at Moda Health, State Farm, USAA or Everence before reaching Humana on the cost ranking.

State Farm
Average Plan G Rate
$187Plan Types
A, C, D, F, G, N
- pros
Offers best rates for Plan D
Six plan types, including less common but valuable options (D, F)
Superior AM Best rating
consNo cost-sharing plans (K or L) or high-value Plan M
State Farm holds the lowest Plan D rate in Arizona at $189 per month, $85 below the state average. Plan D covers most Medicare gaps, including the Part A deductible, coinsurance and copayments, but does not cover Part B excess charges or the Part B deductible.
Monthly premiums across State Farm's six available plans range from $146 to $348 based on plan selection and enrollment age. Members who prefer in-person guidance can work with State Farm's network of local agents to manage their Medicare coverage.
State Farm's six-plan lineup excludes Plans B, K, L and M. Arizona seniors who want Plan K or L for predictable out-of-pocket caps will need to look elsewhere; AARP and Humana both offer cost-sharing plans in the state. For Plan G, WMI Mutual's $161 rate runs $28 per month less than State Farm's $189.

AARP
Average Plan G Rate
$203Plan Types

Provides excellent Plan K rates in Oregon ($66 a month)
Eight plan types including cost-sharing options K and L
consDoesn't offer Plans D or M
AARP has the lowest rate for Plan K in Oregon at $66 per month, which is $34 less than competing options. Members can choose from eight Medigap plans: A, B, C, F, G, K, L and N, with monthly premiums ranging from $66 to $353 based on plan selection. These plans are backed by UnitedHealthcare, which holds an A financial strength rating from AM Best. AARP also provides education resources and advocacy for seniors beyond insurance decisions.
AARP's Plan G rate of $203 per month ranks fifth among the seven Oregon Plan G providers per MoneyGeek's analysis. For seniors whose main goal is the lowest Plan G premium, Moda Health ($185), State Farm ($187) or USAA ($188) each save $15 to $18 per month or $180 to $216 annually, for the same standardized coverage. AARP's strength is plan variety and its Plan K pricing, not Plan G value.

Transamerica

Plan M rates are the best in Oregon ($180 a month)

Plan G rates may be less competitive than other insurers
Transamerica is the only Medigap company in Oregon offering all 10 standardized plan types, giving seniors complete flexibility in choosing coverage. The insurer holds the best rate for Plan M in Oregon at $180 monthly. With a cost range spanning $99 to $484, it covers every budget across plans A through N.
Transamerica's average Plan G rate of $221 monthly is $36 more per month than Moda Health's $185, adding up to $432 per year for the same standardized benefits. Seniors who want Plan G and care about price should start at the lower end of the table. Transamerica earns its place for seniors who want Plan M or need access to all 10 plan types in one place.

Best Medicare Supplement Plan N in Oregon
Plan N trades lower premiums for predictable copays. Everence Association charges $128 monthly while AARP charges $159. That $31 gap equals $372 per year. Most Oregon seniors pay those copays less often than the premium difference between Plan N and Plan G would cost them. Bankers Life and State Farm are at $143 and $145, respectively.

How to Choose the Best Medicare Supplement Plan
Price and plan letter are only part of the decision. Rate stability over time, the insurer's financial strength and claims handling quality all matter equally for a plan you may carry for 20 or more years.
- 1Assess Your Health Care Needs
Do you travel frequently? How often do you see doctors? More coverage costs more monthly but saves money when you need care. If you have ongoing 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 and is the right starting point for most Oregon seniors enrolling in 2026. Plan N provides similar benefits with lower premiums plus modest copays ($20 for doctor visits, $50 for emergency room). At $57 less per month than the cheapest Plan G, it saves money if you average fewer than three extra doctor visits per year. Plan F, available only if you enrolled in Medicare before 2020, covers all out-of-pocket costs, including the Part B deductible. USAA leads Oregon Plan F pricing at $197 per month.
Plans K and L cost less monthly but require you to pay a percentage of costs until you hit an annual limit. They're the right choice when the monthly premium is the priority. See how Medicare Advantage plans in Oregon compare if you haven't ruled out that coverage path, since the two approaches can't be combined.
- 3Get Quotes From Multiple Providers
Get quotes from at least three companies. Insurers charge different rates for identical coverage, and the gap can be hundreds of dollars per year.
- 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 cost less over the long term for most seniors.
- 5Check Company Ratings
Review AM Best ratings for financial stability and customer satisfaction scores for service quality. Lower premiums aren't worth much 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.
Oregon Medicare Resources
Oregon residents needing help with Medicare coverage and enrollment options can look into the below multiple resources that provide free state and federal assistance.
- Oregon Senior Health Insurance Benefits Assistance (SHIBA): State-trained volunteers counsel Oregon residents about Medicare at no charge. SHIBA advisors explain Medigap policies, prescription drug plans and fraud prevention. No volunteers sell insurance or collect commissions. All guidance stays unbiased. Call local offices to arrange counseling appointments.
- Oregon Department of Consumer and Business Services: : This state agency publishes annual guides comparing Medigap rates from all approved insurers. A consumer helpline answers questions about billing disputes and coverage problems. Staff investigate complaints and enforce Oregon insurance laws protecting state residents.
- Oregon Area Agencies on Aging: Regional offices throughout Oregon coordinate Medicare enrollment help and benefits counseling. Staff connect older Oregonians with community programs, caregiver support and health services statewide. Each area has local aging services available to residents.
- Medicare.gov: CMS operates this federal website with complete Medicare information. The plan finder displays every Medigap, Medicare Advantage and Part D option in your ZIP code. Compare premiums, benefits and quality ratings side-by-side. Enrollment periods and federal coverage rules are explained throughout the site.
Which Is the Right Medicare Supplement Plan for You?
For most Oregon seniors enrolling in 2026, Plan G from Moda Health at $185 per month is the right starting point. The savings versus the state's Plan G average of $224 add up to $468 per year for coverage that federal law makes identical regardless of which insurer you choose. If Moda Health's four-plan lineup doesn't cover what you need, State Farm at $187 is the next-best Plan G rate and adds Plans C and D to the mix.
Transamerica is the only company in Oregon offering all 10 plan types. Its rates don't lead on price for any individual plan. Transamerica is the right choice if plan flexibility matters more than rate. But if Plan G is your target, start at the top of the price table and work down.
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.
Can I switch Medicare Supplement plans in Oregon after open enrollment?
You can apply to switch Medigap plans in Oregon at any time, but insurers can use medical underwriting outside your open enrollment window. That means a carrier can charge you more or deny coverage based on your health history. Oregon does not require insurers to accept all applicants after the six-month open enrollment period ends, so switching plans after that window carries real risk if your health has changed since you first enrolled.
Does Oregon have any guaranteed issue rights beyond the open enrollment window?
Yes. Oregon law gives you guaranteed issue rights in specific situations outside open enrollment: if your Medicare Advantage plan leaves the area or stops covering your county, if you move out of your plan's service area or if you lose coverage through no fault of your own. In these situations, insurers must accept your Medigap application without medical underwriting. Contact Oregon's SHIBA program at no cost to confirm whether your situation qualifies before applying.
Our Methodology
MoneyGeek collected Oregon Medicare Supplement data for 65-year-olds and 75-year-olds using Medicare.gov's plan browsing tool in June 2026. Rates reflect a nonsmoker profile with no medical underwriting applied, consistent with open enrollment eligibility. We evaluated 13 providers offering coverage in Oregon across all 10 standardized plan types. 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.
