Filed rate actions
A rate action is the increase a carrier asked the state to approve on an existing block of Plan G policies. It is separate from the age increase built into an attained-age premium, and it is the number that tells you how a carrier has treated the people already holding the policy.

Rates and approved increases change. Past rate increases do not predict future increases. Verify current pricing with the carrier or the issuing state's insurance department before making a decision.
What Plan G covers
Plan G covers everything Plan F covers except the Part B deductible, which you pay once a year. It is the plan most people compare first, and the one with the deepest, most competitive set of filings in nearly every state — which is what makes its rate history the clearest read on how a carrier behaves over time.
With Plan G, you still pay:
- The Part B annual deductible
Benefits are standardized by federal law, so Plan G from one carrier pays the same claims as Plan G from another. Price, rate-increase history and service are what differ. That is the whole argument for reading filings.
Switching Plan G carriers in Washington
There is no annual open enrollment period for Medigap in Washington: if you already hold a Medigap policy you may apply to buy or switch at any time, and a company offering a Plan B through N must accept you for it. If you do not currently hold a Medigap policy, whether an insurer may ask you to pass a health questionnaire varies — check before you apply.
Washington: apply to switch at any time. State rules change; confirm the current window with the Washington insurance department or your SHIP counselor before you apply anywhere.
