California Medicare Supplement guide

Medicare Supplement insurance (Medigap) works with Original Medicare to help pay certain deductibles, copays, and coinsurance. This is general education for California. It is not a plan recommendation and not an enrollment.

What Medigap does — and does not do

You keep Part A and Part B. A standardized Medigap letter helps with some of the costs Original Medicare leaves behind. It generally does not include Part D prescriptions, and it generally does not add dental, vision, or hearing extras. You usually add a separate Part D plan if you need outpatient drug coverage.

Letters, not company names

In California, Medigap benefits are standardized by letter (for example Plan G or Plan N). Plan G from one company is designed to cover the same core benefits as Plan G from another. Premiums, household discounts, and rate history are not standardized. This website does not name a “best” company or letter.

When you can buy without health questions

Federal guaranteed-issue rights are strongest during Medigap open enrollment — typically the six months after you are 65 or older and enrolled in Part B. California also has an annual birthday window for people who already have Medigap (see the Birthday Rule article). Outside those windows, insurers may use medical underwriting. Confirm current rules with the California Department of Insurance and Medicare.gov.

Plan F and newly eligible people

Plan F is generally not available to people newly eligible for Medicare after January 1, 2020. People who already have Plan F may keep it. Ask for the outline of coverage before you compare premiums.
