Does California use HealthCare.gov?

No. California runs its own state-based Marketplace called Covered California. Californians enroll at coveredca.com instead of HealthCare.gov. Covered California has been operating since 2014 and is one of the largest and most successful state-based exchanges in the country.

Medi-Cal is California's Medicaid program. It is free or low-cost coverage for eligible Californians. California expanded Medi-Cal under the ACA, and as of 2024 has extended full-scope Medi-Cal to all income-eligible Californians regardless of immigration status — a unique policy in the country. Adults up to 138% FPL qualify.

What is California's state subsidy program?

California adds state-level subsidies on top of the federal Premium Tax Credit through the California Premium Subsidy program. This makes Covered California plans more affordable for middle-income enrollees. California also caps maximum premiums as a percentage of income — one of the more generous state add-ons.

What insurance companies sell Obamacare plans in California?

The major carriers on Covered California for 2026 include Kaiser Permanente, Blue Shield of California, Anthem Blue Cross, Health Net, L.A. Care Health Plan, Sharp Health Plan (San Diego), Western Health Advantage (Sacramento), Molina Healthcare, Oscar Health, and Valley Health Plan.

Can undocumented immigrants get coverage in California?

As of January 2024, all income-eligible undocumented adults qualify for Medi-Cal in California. This does not extend to Covered California Marketplace plans, but Medi-Cal covers a similar set of benefits at no or very low cost.

When is Open Enrollment in California?

Covered California has historically extended Open Enrollment beyond the federal calendar. For 2026 coverage, Covered California Open Enrollment runs November 1, 2025 through January 31, 2026. Medi-Cal accepts applications year-round, with no Open Enrollment window required.

How Obamacare works in California

California runs its own state Marketplace at Covered California. Operating since 2014, it is one of the largest and most successful state-based exchanges in the country.

The basic flow:

Enter your zip code, household size, and estimated 2026 income at CoveredCA.com or with a licensed agent.
The site checks Medi-Cal first. If you do not qualify, it shows Covered California plans with both federal and state subsidies applied.
Compare plans by premium, deductible, network, and the carriers in your region.
Pick one and enroll. Coverage starts the first of the next month.

California expanded Medi-Cal under the ACA — and went further. As of January 2024, all income-eligible Californians qualify for full-scope Medi-Cal regardless of immigration status. This is unique in the country.

California is the most expansive coverage state. Talk to a licensed California agent — free, Spanish available.

California Premium Subsidy — extra state help

In addition to the federal Premium Tax Credit, California funds its own state-level subsidies called the California Premium Subsidy. This program:

Caps the premium percentage that enrollees pay based on income
Helps middle-income Californians who would otherwise see smaller federal subsidies
Automatically applies when you enroll through Covered California
Has fluctuated in size depending on state budget decisions

For a family of four earning $90,000, the California Premium Subsidy can reduce monthly premiums by $50 to $200 on top of what the federal subsidy provides.

San Bernardino & Riverside Counties / Inland Empire (~52% Hispanic combined) — Mexican

Common California-specific questions

“I am undocumented — can I really get Medi-Cal?” Yes, if you are income-eligible. As of January 2024, full-scope Medi-Cal is available to all income-eligible California residents regardless of immigration status. Application is at the county social services office or through Covered California.

“I am self-employed — can I get Covered California?” Yes. The Marketplace uses estimated annual income. Self-employed, freelancers, gig workers, and contractors all qualify. The California Premium Subsidy makes middle-income coverage more affordable.

“My employer offers insurance but it is too expensive.” If your employer’s self-only plan would cost more than 9.12% of your household income in 2026, you may qualify for a Covered California subsidy instead.

“I have a pre-existing condition.” Cannot be used against you. Federal law since 2014.
