Navigating Medicare in Washington in 2026

CONTINUOUS ENROLLMENT AND STATE CONSUMER PROTECTIONS

Enrolling in Medicare can often feel like a one-way street. In most parts of the country, once a beneficiary selects a Medicare Supplement (Medigap) plan, switching policies later in life requires passing a rigorous health questionnaire. Developing a chronic condition or needing a new prescription can make moving to a different plan virtually impossible. For retirees living in Washington State, however, the rules offer far greater flexibility. Washington maintains some of the strongest consumer protection laws in the nation for Medicare beneficiaries, offering year-round flexibility and initiatives designed to reduce administrative red tape.

Here is a detailed look at how Washington’s specific Medicare rules work and how beneficiaries can use them to protect both their health access and their monthly budget.

Continuous Open Enrollment for Medigap

The most significant advantage for Washington residents enrolled in Original Medicare is the state’s Continuous Open Enrollment rule for Medicare Supplement insurance.

How Year-Round Switching Works

Under Washington Administrative Code (WAC), if you are currently enrolled in a Medigap policy (Plans B through N), you have the legal right to switch to another Medigap policy (Plans B throughN) at any time during the year.

Unlike the federal rules that apply in most other states:

• No Medical Underwriting: You cannot be denied coverage or charged a higher premium based on your age, pre-existing conditions, or health history.
• No Waiting for Annual Windows: You do not have to wait for the fall Annual Enrollment Period (AEP) to adjust your Medicare Supplement coverage
• Guaranteed Issue: The new insurance carrier must accept your application as long as you are moving from an existing Medigap plan.

Eliminating the “Fear of the Wrong Plan”

When seniors turn 65, choosing between a high-coverage policy like Plan G and a lower-premium policy like Plan N can create significant decision fatigue.

Washington’s continuous enrollment rule removes this pressure. A beneficiary can begin their Medicare journey with the comprehensive coverage of Plan G. If, several years later, their fixed income changes and they prefer lower monthly premiums, they can transition to Plan N without worrying about a health exam. Conversely, if a beneficiary wants to adjust their
coverage level to reduce out-of-pocket copays, the state framework protects their right to do so.

Important Distinction: Continuous open enrollment applies specifically to switches between Medigap plans (Supplement-to-Supplement). It does not allow an individual to switch from a Medicare Advantage (Part C) plan to a Medigap plan year-round without meeting specific federal qualification criteria or passing health underwriting.

The WISeR Model in Washington

WISeR stands for Wasteful and Inappropriate Service Reduction. Washington is one of six states participating in this federal model, which runs from 2026 through 2031. For selected Original Medicare services, providers may request prior authorization or undergo review after the service and before payment. The model does not change Medicare coverage policies. Ask your provider whether a planned service is included and how the review applies to your care.

Frequently Asked Questions (FAQ)

a) Can I switch my Medigap plan in Washington if I recently developed a health condition?

Yes. Under Washington state law, as long as you are currently enrolled in a Medigap plan (Plans B through N), insurance carriers offering those plans cannot ask medical screening questions when you apply to switch to another plan (Plans B through N).

b) Does Washington’s year-round rule apply to Plan A or Plan F?

Plan A and legacy Plan F have specific state enrollment rules. While Plans B through N fall under the standard continuous open enrollment framework, it is always best to verify the exact plan movement rules with a licensed local broker before submitting a cancellation request to your current carrier.

c) How do I make sure there is no gap in my coverage when switching?

To avoid a gap in coverage, never cancel your existing Medicare Supplement policy until your new policy has been formally issued with an established effective date (typically the 1st of the following month).
