How Medicare Pays for Your Advocate in California

Original Medicare

Since January 2024, Medicare covers professional healthcare navigation (Principal Illness Navigation and Community Health Integration). Part B pays about 80%; a Medigap plan typically covers the rest, so most members pay $0.

Medicare Advantage

About 51.2% of California's Medicare beneficiaries in 2025 are enrolled in a Medicare Advantage plan rather than Original Medicare. Acceptance varies plan by plan. Tell us which plan you have and we confirm what it covers before any work begins. No surprise bills, ever.

Not sure what you have?

That is a normal place to start. Read your red-white-and-blue card to us over the phone and we will explain your coverage in plain English, whether or not you sign up.

California is different

Four California Rules and Programs Worth Knowing

Medicare is federal, but the rules and assistance programs around it change at the state line. These four are specific to California, and your advocate works with them every week.

Medigap: the birthday rule lets you switch every year

California is one of the most flexible states for Medigap. On top of the one-time six-month Open Enrollment Period at 65, California's birthday rule (Cal. Ins. Code section 10192.11) gives you a 60-day window every year, beginning on your birthday, to move to a Medigap policy with equal or lesser benefits from any insurer, with no medical underwriting and no new waiting period. It repeats for life. California also requires insurers to offer at least one Medigap plan to beneficiaries under 65 who qualify through disability (this requirement does not extend to people under 65 whose Medicare is because of ESRD). Knowing when your window opens, and what you can move to, is exactly where an advocate earns their keep.

HICAP: free state Medicare counseling in all 58 counties

California's State Health Insurance Assistance Program is HICAP (the Health Insurance Counseling and Advocacy Program), run by the California Department of Aging and delivered by trained, commission-free volunteer counselors through local programs and Area Agencies on Aging statewide. Statewide helpline: 1-800-434-0222. Counselors take no commissions and sell nothing. Great for one-off enrollment questions; we point our own members there during Open Enrollment.

Extra Help, the Medicare Savings Programs, and no Medi-Cal asset test

California does not run a state prescription-assistance program, so the drug-cost help here is federal: many Californians qualify for Extra Help (the Part D Low-Income Subsidy) but never enroll. On top of that, Medi-Cal (California's Medicaid) runs the Medicare Savings Programs as QMB, SLMB, and QI to help cover Part B premiums and cost-sharing. As of January 1, 2024, California became the first state to eliminate the Medi-Cal asset test entirely, so the Medicare Savings Programs, the Aged & Disabled program, and long-term care now look only at income, not savings. Apply through BenefitsCal (benefitscal.com), your county Medi-Cal office, or by calling 1-800-541-5555. Screening for every one of these is standard advocate work, and most eligible seniors never claim them.

IHSS, Medi-Medi Plans, and PACE (Medi-Cal)

California's Medi-Cal alternatives to a nursing facility start with In-Home Supportive Services (IHSS), which pays for in-home care so a person can stay home; it is administered by your county under the Department of Social Services, and California is one of the few states where IHSS can pay a family member, including a spouse, to be the caregiver. Medi-Medi Plans are California's aligned Medicare and Medi-Cal plans for dual-eligible adults, which replaced Cal MediConnect at the end of 2022. PACE (Program of All-Inclusive Care for the Elderly) bundles all care for dual-eligible adults 55 and older who need a nursing-facility level of care, and California has the largest PACE presence in the country. These are Medi-Cal programs; for dual-eligible families we handle the Medicare side while you run the caregiving.

California Questions, Answered

Yes. Since January 2024, Medicare pays for professional healthcare navigation through Principal Illness Navigation and Community Health Integration services. Medicare Part B covers about 80% of the cost, and a supplemental (Medigap) plan typically covers the rest, so most California members pay $0. We confirm exactly what your coverage looks like before your first session, and there are no surprise bills.

Open icon

Yes, all 58 counties. The service is fully virtual, delivered by phone, video, and secure messaging, so it works the same in Los Angeles, San Diego, San Jose, San Francisco, Fresno, Sacramento, Long Beach, Oakland, Bakersfield, and every county in between. There is no office to travel to.

Advocates work virtually and are matched to you, not to a zip code. What matters is that your advocate is the same person every time (One Advocate, For Life), knows California's programs like the Medigap birthday rule, HICAP counseling from the California Department of Aging, the Medicare Savings Programs, In-Home Supportive Services (IHSS), Medi-Medi Plans, and PACE, and gives you their direct phone, email, and text, so you never start over with a stranger in a call queue.

California is one of the best states in the country for this. Beyond the one-time six-month Medigap Open Enrollment Period at 65, California's birthday rule gives you a 60-day window every year, beginning on your birthday, to switch to a Medigap policy with equal or lesser benefits from any insurer, with no medical underwriting (Cal. Ins. Code section 10192.11). It repeats for life, with no age cap. California also requires insurers to offer at least one Medigap plan to beneficiaries under 65 who have Medicare because of a disability (people under 65 with ESRD are not covered by that requirement). Timing that birthday window is exactly where an advocate helps.

Those are Medi-Cal programs (Medi-Cal is California's Medicaid). In-Home Supportive Services (IHSS) pays for in-home care so a person can stay home instead of a facility, and California is one of the few states where it can pay a family member, including a spouse, to be the caregiver; it is run by your county under the Department of Social Services. Medi-Medi Plans are California's aligned Medicare and Medi-Cal plans for dual-eligible adults (they replaced Cal MediConnect in 2023). PACE (Program of All-Inclusive Care for the Elderly) bundles all care for dual-eligible adults 55 and older at a nursing-facility level, and California has the largest PACE presence in the country. Our advocacy is billed through Medicare, so we focus on the Medicare side: bills, appeals, appointments, coverage questions. For dual-eligible families that split works well: you manage the caregiving, and your parent's advocate handles the Medicare paperwork.

HICAP (the California Health Insurance Counseling and Advocacy Program, reachable at 1-800-434-0222), is California's free Medicare counseling service, run by the California Department of Aging with trained, commission-free counselors, and it is excellent for one-off questions. Understood Care is different: a dedicated advocate who does the work itself, makes the calls, files the appeals, untangles the bills, and stays with you month after month, covered by Medicare. The two are complementary, and we often point our own members to HICAP counselors for enrollment-season plan comparisons.
