State Farm at a glance
State Farm Insurance has Washington-approved Medicare Supplement premiums for Plan A, Plan D, Plan G, Plan N, Plan C, and Plan F. Its Plan G costs $310 a month, 10th lowest of 17 insurers. That is $77 a month ($924 a year) more than the lowest Plan G we track, for the same standardized benefits. Its Plan N is $71 a month less than its own Plan G; whether that saving beats Plan N's office and ER copays depends on how often you see the doctor (see Plan G vs Plan N). The OIC chart says to call a local State Farm agent. State Farm sells through its own captive agents. The OIC chart shows it can apply a pre-existing condition waiting period. Washington caps that wait at three months, and it doesn't apply when you replace Medigap or other coverage you've had for at least three months. It can ask health questions when you apply outside a protected period such as your Medigap open enrollment. Washington's switching rule still lets anyone with Plan B through N move to its Plan B through N with no health questions.

Policy terms. State Farm Insurance Medicare Supplement policies are guaranteed renewable, as all Medigap policies are. This insurer may apply a pre-existing condition waiting period of up to three months (none if you replace coverage you've had for three months), and may ask health questions outside guaranteed-issue periods. Medigap policies don't cover prescription drugs, routine dental, vision or hearing care, hearing aids, or long-term custodial care. Plans C and F are only for people first eligible for Medicare before 2020. Premiums can change with state approval. For the policy form number, complete benefits, exclusions and limitations, see the insurer's outline of coverage, which you receive before you apply.

Common questions
How much is State Farm Medigap Plan G in Washington?
$310 a month for anyone 65 or older, on the OIC chart current as of October 8, 2026. That ranks 10th lowest of the 17 Washington insurers we compare.
Is State Farm Medigap available everywhere in Washington?
Yes, in all 39 counties.
Will State Farm raise my premium as I get older?
Not because of age. Washington's community rating rule means it charges every 65+ policyholder the same premium for a plan. It can still raise premiums for all policyholders after a rate increase is approved by the state.
