Medicare Supplement Plans in Washington — Priced Fairly, Explained Clearly

Washington has its own rules around how Medigap plans are priced, and most brokers selling here never mention them. I do. As an independent Medicare Supplement broker serving Pierce, Kitsap, Mason, and the surrounding counties, I help you compare plans based on your actual medical needs — not a script.

What Medicare Supplement Insurance Actually Covers

Original Medicare pays a significant share of your medical costs, but it leaves gaps — copays, coinsurance, and the Part A deductible — that can add up quickly if you're managing a serious condition or frequent care. A Medicare Supplement plan, also called Medigap, wraps around your Original Medicare coverage to pay some or all of those remaining costs.


Medigap plans are sold by private insurance companies but standardized by the federal government. That means a Plan G from one carrier covers exactly the same benefits as a Plan G from another. What differs is the monthly premium, the carrier's financial stability, and whether you're working with someone who can compare those options side by side on your behalf.

What is Medicare?

Medicare is a government-run health insurance program that helps cover healthcare costs for eligible individuals. It consists of different parts, each covering specific medical services, from hospital stays to prescription drugs.


Medicare is divided into four main parts:

  • Medicare Part A – Covers hospital stays, skilled nursing care, hospice care, and some home healthcare services.
  • Medicare Part B – Covers doctor visits, outpatient care, preventive services, and medically necessary treatments.
  • Medicare Part C (Medicare Advantage) –  An alternative to Original Medicare, offered by private insurance companies, combining Part A, Part B, and often Part D coverage, along with extra benefits.
  • Medicare Part D –  Covers prescription drugs, helping lower out-of-pocket medication costs.


Understanding these parts will help you decide which combination of coverage best meets your healthcare and financial needs.

Washington's Community-Rating Rule Changes the Math

In most states, Medigap carriers price plans by age — meaning your premium rises every year simply because you're getting older. Washington state does not allow that. Washington requires Medicare Supplement plans to be community-rated, which means every enrollee in a plan pays the same base premium regardless of age or health status.


This is one of the most important state-specific details in Washington Medicare planning, and it's one that many online guides and out-of-state brokers overlook entirely. Community rating doesn't eliminate premium increases, but it does mean your age alone cannot be used to price you out of a plan.


Washington State Office of the Insurance Commissioner publishes the community-rating requirement as part of its Medigap regulations.

Plan G and Plan N: The Two Plans Most Washington Seniors Are Comparing

For most people enrolling in Medicare Supplement plans Washington today, the real decision comes down to Plan G and Plan N. Here's how they differ.

Medicare Part A

For hospital stays, skilled nursing care, hospice, and some home healthcare.

Plan G

The most comprehensive Medigap option available to new Medicare enrollees. Plan G covers the Part A deductible, skilled nursing coinsurance, Part B coinsurance, and foreign travel emergency care. Your only out-of-pocket exposure is the annual Part B deductible, which is set by Medicare each year. If you want the most predictable cost structure and see doctors or specialists regularly, Plan G is typically the right fit.

Plan N

Plan N covers the same core benefits as Plan G but introduces modest cost-sharing at the point of care — a copay of up to $20 for office visits and up to $50 for emergency room visits that don't result in inpatient admission. In exchange, Plan N premiums run meaningfully lower than Plan G in most markets. If you're in good health, see doctors infrequently, and want to keep your monthly premium down, Plan N can be the smarter financial choice.

Medicare Part A

For hospital stays, skilled nursing care, hospice, and some home healthcare.

What Medigap Costs in Washington State

Because Washington uses community-rated pricing, premiums are more consistent here than in many other states. That said, rates still vary by carrier, by plan letter, and by where you live in the state.


A few things that shape your premium:

The plan letter you choose (Plan G carries a higher premium than Plan N)

Whether you qualify for any household or annual pay discounts

The best way to see actual figures is to compare current carrier rates side by side for your specific zip code. That's exactly what I do during a free consultation — pull the current rate sheets and walk through them with you.

Many seniors assume that once they're enrolled in a Medicare Supplement plan, they're locked in — that switching later would require passing medical underwriting. That's not always true in Washington.


Certain circumstances — including plan terminations and specific enrollment windows — can trigger guaranteed-issue rights that allow you to switch plans without medical underwriting. If you've had your current Medigap policy for a while and you're wondering whether a lower premium or better coverage structure is available, it's worth a conversation.


I've helped clients in Pierce County, Kitsap County, and Mason County navigate plan changes they didn't know were possible.

Questions About Medicare Supplement Plans in Washington

  • What Medicare Supplement plans are sold in Washington state?

    Washington carriers offer the full range of standardized Medigap plan letters, including Plan A, Plan B, Plan D, Plan G, Plan K, Plan L, Plan N, and high-deductible Plan G. Plans C and F are still available to those who became eligible for Medicare before January 1, 2020. For most new enrollees today, Plan G and Plan N are the most widely available and most commonly compared options.

  • How much does a Medigap plan cost in Washington?

    Premiums vary by carrier, plan letter, and county, but Washington's community-rating requirement means your age cannot be used to set your individual rate. As a general range, Plan G premiums in western Washington typically run between $120 and $200 per month, and Plan N runs somewhat lower. The only way to get accurate figures for your zip code is to pull current carrier rate sheets — which I do at no charge during a consultation.

  • Can I switch Medicare Supplement plans after I've already enrolled?

    In most states, switching Medigap plans after your initial enrollment window requires medical underwriting — meaning a carrier can decline you based on health history. Washington has some protections that may allow guaranteed-issue switches in certain situations, such as when a plan is discontinued. Whether you qualify depends on your specific circumstances. I can review your current plan and tell you what options are available.

  • Is a Medicare Supplement plan better than Medicare Advantage?

    They're different structures, not a simple better-or-worse comparison. Medicare Supplement plans work alongside Original Medicare and typically offer broader provider access with more predictable out-of-pocket costs. Medicare Advantage plans often carry lower monthly premiums but use networks and may include prior authorization requirements. The right fit depends on your health, your doctors, and how you use your coverage. I cover this comparison in detail on the Medicare Advantage vs. Medicare Supplement page.

  • Do I need a separate Part D plan if I have a Medicare Supplement policy?

    Yes. Medigap plans do not include prescription drug coverage. If you have a Medicare Supplement plan and want drug coverage, you'll need to enroll in a standalone Part D prescription drug plan. I can help you compare Part D options alongside your Medigap plan so your total coverage picture makes sense.
