Under California law (CIC Section 10192.11), when does the Medigap open enrollment period occur, and what protection does it provide?

Why A is correct

California's Medigap open enrollment is a one-time six-month window that starts when an individual is 65 or older and is enrolled in Medicare Part B. During this period, Medigap insurers must accept the applicant and may not use medical underwriting to deny coverage or charge more for health conditions — guaranteed issue in the open enrollment window. Missing this window means future Medigap purchases may be medically underwritten. This is a California-specific Medigap sales rule under CIC Section 10192.11, tested under AH-III.D.1e, and it is distinct from the federal fall election period.

Why the other options are wrong

• B) The fall Annual Election Period (Oct 15 - Dec 7) is for Medicare Advantage and Part D changes; Medigap open enrollment is a separate one-time window.
• C) The window begins at 65 plus Part B enrollment and runs six months; it is not a three-month pre-65 window.
• D) The open enrollment window is tied to age 65 and Part B enrollment, not to age 70.

Memory hook

65 + Part B = start the six-month clock. Insurance must take you, no questions about health.

Why A is correct

California's Medigap open enrollment period, codified in the insurance code around Section 10192, begins when a person age 65 or older enrolls in Medicare Part B and lasts for six months. During this window, insurers must offer Medigap coverage on a guaranteed-issue basis: they cannot decline an applicant, impose preexisting condition waiting periods, or charge more because of health status. After the window closes, medical underwriting generally applies and coverage may be harder to obtain. The six-month, no-underwriting open enrollment is a California-specific Medigap rule and a frequent exam question in the senior health products section.

Why the other options are wrong

• B) Medigap open enrollment begins at 65 with Part B enrollment, not at age 62.
• C) Medicare Advantage enrollment is a separate decision and does not start the Medigap window.
• D) The window opens upon Part B enrollment and turning 65, not upon filing a claim.

Memory hook

First six months after Part B at 65 = Medigap's open door, no health questions.
