The Medicare Supplement Mistake Washington State Retirees Make
By Seth Deal, CPA/PFS
A 65-year-old retired Washington State employee, signed up for Medicare and thought he was done. Three months later, he received a hospital bill that shocked him.
"I thought Medicare covered everything," he told me during a call. The reality hit hard: Medicare Part A required a $1,676 deductible, and Medicare Part B only paid 80% of his outpatient costs, leaving him responsible for the remaining 20%.
His mistake? He skipped Medicare Supplement Insurance, assuming it was unnecessary. That one decision cost him thousands in unexpected medical bills and left him financially vulnerable.
If you're a Washington State public employee approaching Medicare eligibility, choosing the right Medicare Supplement plan isn't optional—it's essential. Here's how to avoid a costly mistake and select the coverage that protects both your health and your wallet.
The Medicare Supplement Rules Every Washington Retiree Must Know
1. Original Medicare Leaves Significant Gaps Medicare Part A has a $1,676 deductible per benefit period in 2025¹. Medicare Part B requires a $257 annual deductible plus 20% coinsurance on all approved services². These gaps can create thousands in unexpected costs.
2. Medicare Supplement Plans Are Standardized All Plan G policies provide identical benefits regardless of which insurance company sells them³. The only difference between companies is the premium price and customer service quality.
3. Washington Has Unique Advantages Washington is one of the few states where you can switch between Medicare Supplement plans (Plans B-N) without medical underwriting at any time⁴. This provides flexibility other states don't offer.
4. Timing Matters for Best Rates Your Medigap Open Enrollment Period lasts 6 months from when you enroll in Medicare Part B⁵. During this period, you cannot be denied coverage or charged higher premiums due to health conditions.
5. Plan G Has Replaced Plan F as the Gold Standard Plan F is no longer available to people who became eligible for Medicare after January 1, 2020. Plan G provides nearly identical coverage for a lower premium in most cases.
Your "Coverage Protection" Strategy
Step 1: Compare Plan G vs Plan N
These are the two most popular Medicare Supplement plans for new Medicare beneficiaries, and for good reason.
Plan G Coverage:
- Covers everything except the Medicare Part B deductible ($257 in 2025)
- No copays for doctor visits or emergency room visits
- Covers Medicare Part B excess charges
- Average monthly premium in Washington: $1,582
Plan N Coverage:
- Covers everything Plan G covers except: Medicare Part B deductible ($257 annually) $20 copay for most doctor visits $50 copay for emergency room visits (waived if admitted) Medicare Part B excess charges
- Average monthly premium in Washington: $1,652
The math: If you visit doctors frequently, Plan G may cost less annually despite higher premiums. If you rarely see doctors, Plan N's lower premiums plus occasional copays might save money.
Step 2: Shop Washington's Competitive Market
Washington has multiple insurance companies offering Plan G with significant price differences⁷.
Price range for 65-year-old non-smoking woman:
- Lowest premium: Premera at $121 per month
- Highest premium: UnitedHealthcare at $206 per month
- Potential annual savings: $1,020 by choosing the right company
Key shopping factors:
- Premium pricing method (age-rated vs community-rated)
- Rate increase history
- Financial strength ratings (A.M. Best ratings)
- Customer service reputation
Step 3: Leverage Washington's Unique Switching Rights
Unlike most states, Washington allows Medicare Supplement policyholders to switch between Plans B-N without medical underwriting.
Strategic advantage: You can start with Plan N to save on premiums, then switch to Plan G later if your healthcare needs increase, without answering health questions.
Example strategy: Start with Plan N at age 65 to save $40+ monthly in premiums. If you develop health conditions requiring frequent doctor visits, switch to Plan G to eliminate copays.
Step 4: Consider High-Deductible Options
Some companies in Washington offer High-Deductible Plan G with a $2,870 deductible in 2025.
When it makes sense: If you're healthy and rarely use medical services, the lower monthly premium ($69-80 range) might save money annually even if you hit the deductible.
Break-even analysis: Compare the annual premium savings against the deductible amount to determine if this option fits your situation.
Three Scenarios for Different Needs
The "Comprehensive Coverage Seeker" Choose Plan G for predictable costs and maximum coverage. Best for retirees who want peace of mind and can afford higher premiums for complete protection.
The "Budget-Conscious Optimizer" Choose Plan N for lower premiums with minimal cost-sharing. Best for healthy retirees comfortable with small copays in exchange for monthly savings.
The "Minimal User Strategy" Consider High-Deductible Plan G if you rarely use healthcare services. Best for very healthy retirees who want catastrophic protection at the lowest monthly cost.
Maria chose Plan G because she visits specialists regularly and the comprehensive coverage saves her money despite higher premiums.
Don't let Medicare's gaps create financial hardship in retirement. The right Medicare Supplement plan provides predictable costs and comprehensive protection when you need healthcare most.
Bottom line: Medicare Supplement Insurance isn't optional—it's essential protection against Medicare's significant coverage gaps. Plan G and Plan N offer the best value for most retirees, but the right choice depends on your health needs, budget, and risk tolerance.
