During the Medigap open enrollment period under California law, an insurer:

Why A is correct

California's Medigap open enrollment period under CIC Section 10192.11(a) gives a qualifying applicant guaranteed issue: for an application submitted during the six-month window beginning with the first month the individual is both 65 or older and enrolled in Medicare Part B, the issuer may not deny or condition the issuance of the policy, nor discriminate in its pricing, because of the applicant's health status, claims experience, receipt of health care, or medical condition. Guaranteed issue does not eliminate every preexisting-condition consequence, however. Under Section 10192.11(c), the issuer may still exclude benefits for a preexisting condition during the first six months if it was treated or diagnosed within the six months before coverage began, unless Section 10192.11(b) applies: with at least six months of continuous creditable coverage, the exclusion cannot be imposed at all, and with less, it must be reduced by the creditable coverage. After the open enrollment window closes, medical underwriting generally returns for most applicants.

Why the other options are wrong

• B) During open enrollment an issuer cannot reject the applicant or medically underwrite the policy; a preexisting condition can result only in a limited waiting period of up to six months, reduced or eliminated by creditable coverage - never an outright rejection.
• C) Discriminating in the price of a policy because of health status, claims experience, receipt of health care, or medical condition is expressly prohibited during the open enrollment period.
• D) A Medigap policy is guaranteed renewable; the issuer cannot cancel it merely because claims exceeded premiums, so this option confuses renewability with rescission.

Memory hook

Medigap open enrollment = the take-me-as-I-am window: no medical questions, no denials, guaranteed issue.

Why D is correct

The Medigap open enrollment period begins when a beneficiary is 65 or older and enrolled in Medicare Part B. During this window, insurers must sell a Medigap policy without medical underwriting; they cannot deny coverage or charge more because of health conditions. This guaranteed issue protection is the main reason enrollment timing matters: waiting beyond open enrollment can mean underwriting and denial. The rule protects consumers at the point when they most need supplement coverage. The six-month open enrollment window is the one period when federal law forces a guaranteed-issue market: every Medigap policy must be sold to the applicant regardless of health status. After the window closes, the same applicant faces medical underwriting and can be declined or surcharged, which is why the window is so valuable.

Why the other options are wrong

• A) Denying coverage for health reasons during open enrollment would violate the guaranteed issue requirement. Denial based on health is prohibited during the six-month open enrollment window because medical underwriting is suspended for that period.
• B) Premiums during open enrollment are not risk-rated by the individual's health. Premium surcharges for preexisting conditions are barred during open enrollment; guaranteed issue applies regardless of health status. The premium cannot vary by health status during this window.
• C) Open enrollment is not limited to replacement policies; it applies to initial Medigap purchases at 65. There is no replacement-only rule; the open enrollment right applies to any new Medigap purchase during the window.

Memory hook

Open enrollment = Medigap's no-questions-asked window: no underwriting, no denial.

Why A is correct

The Medigap open enrollment period begins when a person is 65 or older and enrolled in Medicare Part B. During this window, insurers must issue any standardized Medigap policy to the applicant regardless of health status, with no medical underwriting, no denial, and no premium discrimination based on health. This guaranteed issue protection is a core Medigap consumer rule, mirrored in California by CIC Section 10192.11.

Why the other options are wrong

• B) Denying applicants for health reasons during the open enrollment window is prohibited; coverage is guaranteed.
• C) Health-based premium differences are barred during open enrollment; all eligible applicants pay the standard rate.
• D) Physical exams and medical questionnaires are not required during the open enrollment window.

Memory hook

Open enrollment = Medigap's no-questions-asked window: issue guaranteed, health never a factor.
