Policy terms. First Health Life & Health Medicare Supplement policies are guaranteed renewable, as all Medigap policies are. This insurer shows no pre-existing condition waiting period on the state chart, 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. For the policy form number, premiums, complete benefits, exclusions and limitations, see the insurer's outline of coverage, which you receive before you apply.
Buying Aetna (First Health) Medigap in King County
First Health Life & Health is one of the insurers approved to sell Medicare Supplement policies in Washington. For King County residents it offers Plan A, Plan B, Plan G, Plan N, and Plan F. Because it sells both Plan G and Plan N, you can compare the two side by side from one insurer: same company and service, different premium and cost-sharing. Its premium for a plan is the same for every policyholder 65 and older under Washington's community rating rule, so a quote for a King County resident is the same as one for a resident anywhere else it sells. If you already have Medigap Plan B through N with another insurer, you can switch to this insurer's Plan B through N at any time without health questions.
