Medicare before 65 usually comes with Social Security disability benefits, after a 24-month wait, or immediately with ALS or kidney failure. The federal dates are the same; California adds Medigap rights that many states do not.
Under 65 with Medicare: California guarantees a Medigap window
People with Medicare because of a disability get a six-month Medigap open enrollment in California when Part B starts, and a second one at 65. Premiums for people under 65 can be higher, and some plans are not offered; HICAP explains the current options.

Medigap has one six-month window with no health questions
It starts the first month you are 65 or older and enrolled in Part B. During those six months a company must sell you any Medigap policy it offers, at the same price as someone in good health. Outside it, rights vary by state.
