California Dual Eligibles: Eligibility, Costs, and D-SNPs

California dual eligibles are residents enrolled in both Medicare and Medi-Cal, a combination that typically leaves them paying nothing out of pocket for medical care. Medicare acts as the primary insurer, and Medi-Cal pays the deductibles, coinsurance, and copayments Medicare leaves behind while adding dental, vision, hearing, long-term care, and in-home support. About 1.5 million Californians hold this status, and the combined coverage is often worth more than $10,000 a year in cost-sharing alone.

Who Qualifies

There is no single application for dual eligibility. You qualify for Medicare and Medi-Cal separately, and holding both enrollments is what makes you a dual eligible.

Medicare covers people 65 and older, younger adults who have received Social Security disability benefits for at least 24 months, and people with end-stage renal disease at any age.1Medicare. End-Stage Renal Disease Most people get premium-free Part A through 40 quarters of work history, their own or a spouse’s. Those who don’t pay up to $565 per month in 2026.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles

Medi-Cal is California’s Medicaid program, and qualifying as a senior or person with a disability depends on income and, starting in 2026, assets again. The Aged and Disabled Federal Poverty Level program sets income limits around $1,800 per month for an individual and roughly $2,430 for a couple. Exact thresholds adjust periodically, so your county social services office is the place to confirm current numbers.

Full dual eligibility requires enrollment in full-scope Medi-Cal. A restricted or share-of-cost program does not deliver the wrap-around benefits described below.

The 2026 Asset Test Returns

California eliminated the asset test for most Medi-Cal programs on January 1, 2024. That is changing. Effective January 1, 2026, the asset limit comes back for non-Modified Adjusted Gross Income Medi-Cal programs at $130,000 for an individual and $195,000 for a couple, plus $65,000 for each additional household member. Your primary home, one vehicle, and certain other assets are generally exempt, but some people who enrolled during the no-asset-test window will be disqualified when the limits return.

If Your Income Is Too High for Full Medi-Cal

Medicare Savings Programs cover some or all of your Medicare costs if you don’t qualify for full Medi-Cal but your income is still limited. This is called partial dual eligibility.3Medicare.gov. Medicare Savings Programs

The most valuable is the Qualified Medicare Beneficiary (QMB) program. QMB pays your Part A premium (if you owe one), your Part B premium, and every deductible, coinsurance, and copayment Medicare charges. The 2026 income limit is $1,350 per month for an individual and $1,824 for a couple, with resource limits of $9,950 and $14,910. Two other programs, Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI), pay only the Part B premium and use slightly higher income ceilings.

QMB enrollees also get federal protection against being billed for cost-sharing by any provider, Medicaid-participating or not.

What You Pay at the Doctor or Hospital

For full dual eligibles, the math works out to zero on almost every bill. Medicare pays first. Medi-Cal picks up the Part A and Part B deductibles, coinsurance, and copayments, and pays the standard Part B premium of $202.90 per month in 2026.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles

A hospital stay that triggers the 2026 Part A deductible of $1,736 costs a regular Medicare beneficiary that full amount. A dual eligible pays nothing. The $283 Part B annual deductible and the 20% coinsurance on outpatient services are also covered. QMB enrollees who don’t qualify for premium-free Part A also have that premium paid by the state, worth up to $565 per month.3Medicare.gov. Medicare Savings Programs

Providers accept Medicare’s approved amount as payment in full. You should not see a bill for covered services.

What Medi-Cal Adds That Medicare Doesn’t Cover

Eliminating cost-sharing is only half the story. Dual eligibility opens whole categories of care that Medicare simply doesn’t pay for.

Long-Term Care

Medicare covers short-term skilled nursing after a qualifying hospital stay. It does not pay for ongoing custodial care. Medi-Cal does. Nursing facility care, which can run upward of $10,000 per month at private-pay rates, is covered for dual eligibles who need it. Home and community-based services offer an alternative for people who want to stay at home with help for daily tasks like bathing, dressing, and meals.

In-Home Supportive Services

California’s In-Home Supportive Services (IHSS) program pays a caregiver, who can be a family member, to help with housecleaning, meal preparation, laundry, personal care, and accompaniment to medical appointments.4California Department of Social Services. In-Home Supportive Services Program

To qualify, you need active Medi-Cal, you must live in your own home (not a licensed care facility), and your doctor must submit a Health Care Certification form. A county social worker then visits to assess which tasks you can safely do on your own and authorizes a monthly hour allocation for each service. Thorough medical documentation from your physician makes a real difference in how many hours you get approved.

Dental, Vision, and Hearing

Original Medicare offers almost no dental coverage, no routine vision care, and limited hearing benefits. Medi-Cal covers all three. Denti-Cal pays for preventive care, fillings, crowns, root canals, and dentures. Vision benefits include eye exams and eyeglasses. Hearing benefits include evaluations and hearing aids.

Prescriptions and Rides to Appointments

All full dual eligibles automatically receive the Low-Income Subsidy, known as Extra Help, for Medicare Part D, which reduces or eliminates Part D premiums, deductibles, and copayments.5Medicare. Help with Drug Costs When a drug isn’t on your Part D plan’s formulary, Medi-Cal provides wrap-around coverage. Medi-Cal also pays for non-emergency medical transportation to and from any appointment the program covers.

One Plan Instead of Two: D-SNPs and Medi-Medi Plans

Dual Eligible Special Needs Plans (D-SNPs) are Medicare Advantage plans built for people with both Medicare and Medi-Cal. Instead of running two separate programs with different networks and ID cards, a D-SNP bundles everything into one managed care plan with a single point of contact.6California Department of Health Care Services. CalAIM Dual Eligible Special Needs Plan Policy Guide

Under California’s Exclusively Aligned Enrollment model, part of the CalAIM initiative, your D-SNP and your Medi-Cal managed care plan are run by the same organization, creating what the state calls a Medi-Medi Plan. As of January 2025, twelve counties participate, including Los Angeles, San Diego, Sacramento, Orange, Riverside, and San Bernardino, with further expansion planned.

D-SNPs often add supplemental benefits such as over-the-counter allowances, grocery benefits, and utility assistance. These vary by plan and county, so comparing options during open enrollment is worth the time. Enrollment isn’t mandatory. You can stay in Original Medicare with a standalone Medi-Cal plan if you prefer.

Don’t Pay a Bill You Don’t Owe

Federal law prohibits providers from billing QMB enrollees for any Medicare cost-sharing, including deductibles, coinsurance, and copayments.7Social Security Administration. Social Security Act Title 19 – 1902 This holds whether the provider participates in Medicaid or not, and regardless of whether Medi-Cal actually reimburses the full cost-sharing amount.8Centers for Medicare & Medicaid Services. Prohibition on Billing Qualified Medicare Beneficiaries

A doctor or hospital that sends you a bill for a Medicare-covered service is violating federal law. Providers who do it face sanctions under their Medicare provider agreement. If you receive a bill you believe is improper, contact your Medi-Cal managed care plan or call 1-800-MEDICARE to report it. Many dual eligibles lose money they shouldn’t simply by paying bills they don’t owe.

How to Apply, and What to Do If You’re Denied

Apply for Medicare through the Social Security Administration online at ssa.gov, by phone, or at a local office. Apply for Medi-Cal through your county social services office, through an online portal depending on your county, or through Covered California, which will route your application to Medi-Cal if you appear to qualify.

If your Medi-Cal application is denied or your benefits are cut, you can request a state fair hearing. For actions taken by the county or the Department of Health Care Services, the deadline is 90 days from the date on the notice. If you’re in a Medi-Cal managed care plan and disagree with a coverage decision, you generally must appeal through the plan first within 60 days; if the plan doesn’t resolve it within 30 days or you disagree with the outcome, you then have 120 days to request a state hearing.9California Department of Social Services. State Hearing Requests

Request a hearing online, by calling the State Hearings Division at (800) 743-8525, or by writing to the address on your Notice of Action. Don’t let a denial sit, particularly on IHSS hours or Medi-Cal eligibility. The return of asset limits in 2026 will produce a wave of termination notices, and many of those determinations will be worth challenging if your countable assets were calculated incorrectly.
