The clearest line.
Medicare is medical insurance. It pays doctors, hospitals, drugs, and short-term rehab. It does not pay for the help your parent needs with meals, bathing, medication reminders, and supervision, day after day. That kind of help is called custodial care or long-term care, and Medicare does not cover it under any circumstance, regardless of how long the need lasts.
Medi-Cal is California’s Medicaid program. It is health insurance, but it also funds the long-term-care system: nursing homes, IHSS, the Assisted Living Waiver, PACE, MSSP, CalAIM Community Supports, and more. If your parent has Medi-Cal, the system has tools you can use. If your parent does not, the tools are mostly out of reach.
What Medicare covers, and where it stops.
- Part A (hospital). Inpatient hospitalization, hospice care, and short-term skilled nursing facility care after a qualifying three-day hospital stay. Up to 100 days of SNF rehab per benefit period, with cost-sharing after day 20.
- Part B (medical). Doctor visits, outpatient services, some preventive care, durable medical equipment, some home health.
- Part D (drugs). Prescription drug coverage, plan-dependent formulary.
- Medicare Advantage (Part C). An alternative to original Medicare. Some plans add limited custodial benefits, but do not assume coverage. Read the plan summary.
Medicare does not pay for: assisted living, residential care for the elderly (RCFE), memory care, long-term nursing home stays (beyond the 100-day rehab benefit), or in-home help that is not skilled medical care.
What Medi-Cal can do that Medicare cannot.
Medi-Cal is the only program available to most California families that pays for ongoing custodial care. It is also the gateway to almost every other long-term services and supports program in the state.
- Long-term nursing home care.Medi-Cal can pay for ongoing nursing facility residence, after Medicare’s 100 days are exhausted or in lieu of Medicare. A nursing-home Medi-Cal application is its own process.
- IHSS.In-Home Supportive Services pays for help with daily living, in your parent’s home. A family member can be the paid caregiver under defined rules. See the IHSS guide.
- Assisted Living Waiver. Medi-Cal may pay rent at a participating licensed RCFE if your parent qualifies and a slot opens. Real waitlist. See the ALW guide.
- CalAIM Enhanced Care Management and Community Supports. Care coordination and services that fill gaps Medicare leaves open. See the CalAIM guide.
- PACE (Program of All-Inclusive Care for the Elderly). A comprehensive Medi-Cal-funded program for nursing-home-eligible seniors who can still live in the community. Available in many California counties.
- MSSP (Multipurpose Senior Services Program). A Medi-Cal waiver for community-based care management. Long waitlists in some counties.
The 2024 asset-limit change, in numbers.
Before 2024, a single Medi-Cal applicant could be disqualified if they had more than $2,000 in countable assets. The asset limit had been raised in stages in 2022 (to $130,000) and 2023 (also high), but most families still assumed they were over it. Effective January 1, 2024, the non-MAGI asset limit was eliminated entirely. As of 2026, income remains the test for eligibility, not assets.
Practical implication: if your parent has a house, a retirement account, and modest savings, but their monthly income is at or below the Medi-Cal limit (which adjusts annually and is roughly 130 percent of the federal poverty level for the relevant household size), they likely qualify. Apply.
Dual eligibility (Medi-Medi) and why it changes the math.
A senior with both Medicare and Medi-Cal has access to the most coordinated care available in the system. Medi-Cal pays Medicare premiums, copays, and deductibles, eliminating the cost-sharing that makes Medicare-only coverage expensive on a fixed income. Medi-Cal also covers services Medicare does not, including long-term care.
Dual eligibles can enroll in a Dual Eligible Special Needs Plan (D-SNP), a Medicare Advantage plan designed for them. D-SNPs in California must coordinate with the member’s Medi-Cal Managed Care plan. The result is closer to a single coordinated system than either Medicare-alone or Medi-Cal-alone.
If you are starting from zero.
Three calls to make, in order:
- Your county Social Services office. Apply for Medi-Cal. If your parent already has Medi-Cal, request the most recent eligibility determination in writing.
- HICAP (Health Insurance Counseling and Advocacy Program). A free service through the California Department of Aging. HICAP counselors help with Medicare and Medi-Cal questions. Call 1-800-434-0222 to be routed to your county HICAP office.
- The discharge planner or social worker, if a hospitalization triggered the question. Ask specifically about CalAIM Enhanced Care Management and CalAIM Community Supports, and document the response.
