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.

Why there are no premiums on this page yet

We publish a premium or a rate increase only after we have found the carrier’s filing in the state’s public records and linked to it on the page. Until that check is done for this plan and state, we show you the structure of what we track and leave the numbers off. A number without a source is worse than no number.

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 Montana

We have not identified a state rule here that goes beyond the federal floor. Outside your one-time six-month open enrollment window, and without a federal guaranteed issue right, an insurer may use medical underwriting and may decline you.

Montana: federal rules only. State rules change; confirm the current window with the Montana insurance department or your SHIP counselor before you apply anywhere.
