Medicare and Senior Health Products in California
10% of the exam 3 min
15 of the 75 Accident & Health questions, the largest single area: Medicare eligibility and Parts A to D, enrollment periods and penalties, Medicare supplements and California's rules, Medicare Advantage, and HICAP.
Who is eligible, and when to enroll
Medicare covers citizens and legal residents 65 or older (legal residents after five years in the U.S.), people who have received Social Security disability for two years, and people with end-stage renal disease or ALS. Part A is premium-free for those fully insured under Social Security; others pay a monthly premium. Part B has a seven-month initial enrollment period, an eight-month special enrollment period after employer coverage ends, and a general enrollment period from January 1 to March 31. Late enrollment costs 10% for each full 12-month period without Part B, for life, and 1% of the base premium for each month without creditable drug coverage under Part D.
What Parts A, B, C and D cover
Part A covers inpatient hospital care (not physician charges), skilled nursing after a qualifying hospital stay, home health and hospice. It has a deductible per benefit period, daily copays for days 61 to 90, and 60 lifetime reserve days. Part B covers physician services and outpatient care, with a monthly premium (higher for high incomes), an annual deductible, generally 80/20 coinsurance and no out-of-pocket maximum. Part C, Medicare Advantage, is private managed care (HMO, PPO, private fee-for-service, special needs plans) that must cover everything Original Medicare does and may add benefits. Part D drug plans are optional, stand-alone or inside an Advantage plan; enrolling in a stand-alone drug plan ends Advantage enrollment, and formularies must include at least two drugs per category.
Medicare supplements and California's rules
Medicare supplement plans are standardized: Plan A's core benefits are in every plan, and the lettered plans add more. Plans covering the Part B deductible (C and F) cannot be sold to people newly eligible since 2020. California guarantees issue during the six months starting the first month a person is 65 and enrolled in Part B (Ins. Code 10192.11), and gives everyone an annual window of at least 60 days from their birthday to switch to a plan with equal or lesser benefits without underwriting (10192.11(h)). Guaranteed issue also applies in specified situations, such as losing other coverage (10192.12). First-year commissions are capped at 200% of the second year's (10192.16). No one may collect from two supplements, and applications ask about existing coverage; Medicare Advantage is not a supplement and does not coordinate with one.
Claims, appeals, HICAP and marketing rules
Under Original Medicare, providers submit claims to CMS; a provider who accepts assignment takes Medicare's approved amount, and the beneficiary gets a Medicare Summary Notice explaining what was paid and how to appeal. HICAP, the Health Insurance Counseling and Advocacy Program, gives free, unbiased help with Medicare, Advantage, supplements and drug plans; the Department of Aging administers it and Area Agencies on Aging run it locally. Agents helping consumers choose plans must follow CMS marketing rules, including the third-party marketing organization disclaimer, call recording and permission to contact.
Where people lose points
✗ "Medigap open enrollment starts at 65 whether or not you have Part B."
✓ It starts the first month you are both 65 and enrolled in Part B, and lasts six months.
✗ "The birthday rule lets me upgrade to a richer plan."
✓ Only to equal or lesser benefits.
✗ "A Medigap policy fills the copays of a Medicare Advantage plan."
✓ Medicare Advantage does not coordinate with supplements.
✗ "Part A pays the surgeon."
✓ Physician and surgeon charges are Part B, even in the hospital.
✗ "Lifetime reserve days renew each benefit period."
✓ The 60 lifetime reserve days are used once and never replenished.
