California runs its own ACA marketplace called Covered California. It is the largest state-based marketplace in the country and has invested more state money into making coverage affordable than most states.
If you live in California, you do not use HealthCare.gov. You use Covered California. The federal site will redirect you.
How Covered California works
The basic structure is the same as any ACA marketplace. You enter household and income details. The site shows plans from multiple insurers. You pick a plan and pay your premium to the insurer or through Covered California.
Plans come in the four metal tiers (Bronze, Silver, Gold, Platinum) plus a Catastrophic tier for those who qualify. All ACA essential health benefits are covered.
The big difference is the financial help layered on top.
Stacked financial help
California has used state dollars to add help beyond the federal premium tax credit.
A state subsidy program has expanded in recent years to lower premiums further for moderate-income enrollees.
California-specific cost-sharing reductions can make Silver plans even more generous in some income bands.
The exact dollars and income thresholds change with each state budget cycle. Covered California publishes the current rules on the Financial Help page.
The practical effect: California residents often pay less than residents of federal marketplace states for the same income and household.
Medi-Cal
If your income is at or below 138 percent of the federal poverty level for your household size, you qualify for Medi-Cal, the California Medicaid program. California has expanded Medi-Cal under the ACA.
Medi-Cal is administered by the Department of Health Care Services (DHCS) and county social services agencies. You can apply through:
Covered California (which sends you to Medi-Cal if you qualify).
Your county social services office.
The state benefits portal at BenefitsCal.com.
California has gone further than most states by expanding state-funded Medi-Cal eligibility to all income-eligible residents regardless of immigration status in recent rule changes. The rules continue to evolve. Confirm current eligibility through DHCS.
Insurer choices in California
Covered California has historically offered plans from a number of carriers, with the exact list varying by region. Common participants have included Blue Shield of California, Anthem Blue Cross, Kaiser Permanente, Health Net, Molina, LA Care, Sharp Health Plan, Western Health Advantage, and others. The full current list and your specific availability depend on your county.
Kaiser is a key consideration in California because it is a closed integrated system. Kaiser doctors only see Kaiser members and Kaiser hospitals only treat Kaiser members. If you want to keep a non-Kaiser doctor, you pick a non-Kaiser plan.
Open Enrollment in California
Covered California typically opens for the next plan year on November 1, matching the federal schedule. The end date has often been later than the federal January 15 cutoff, sometimes extending to the end of January.
The state has expanded Special Enrollment Period rules in some years to include events the federal marketplace does not, such as a significant change in income that affects subsidy eligibility.
Common California-specific situations
A worked example. A self-employed graphic designer in Los Angeles County, household of two, expected annual income $58,000.
Federal premium tax credit applies based on the second-lowest-cost Silver in LA. The state subsidy may layer on top depending on the current rule.
A Silver-CSR plan provides lower deductible and copays.
If income drops mid-year to $32,000, the household may transition into Medi-Cal eligibility, requiring an application through Covered California or BenefitsCal.
Another scenario. Retiree at 62 in Sacramento, retired before Medicare. Income mostly from a pension and a Roth conversion. The Roth conversion bumps annual MAGI into a higher subsidy band but may still leave significant premium tax credit. Plan choice usually comes down to provider network preference (UC Davis Health for academic medicine, Sutter, Dignity, or Kaiser).
Things that catch California residents
Region-based pricing. Covered California has 19 pricing regions. The same plan can cost very differently in a neighboring region. Make sure your ZIP code is right.
Kaiser vs. non-Kaiser networks. Switching between them is a big change. If you have Kaiser doctors, leaving Kaiser usually means new doctors. If you have non-Kaiser doctors, joining Kaiser means new doctors.
Medi-Cal renewal. Like every state, California is working through Medicaid renewals after the pandemic-era continuous-enrollment period ended. Open every letter from the county and respond on time, even if you think you still qualify.
Mixed-status families. California subsidies have specific rules for households with members of different citizenship and immigration statuses. The marketplace handles most of the logic, but documentation can be intensive.
Where to get help
Covered California Service Center. Phone support, multiple languages.
Certified Insurance Agents and Certified Enrollment Counselors. Free help, listed on the Covered California Find Help tool.
Local community organizations. Many counties have nonprofits funded to provide enrollment assistance.

If you qualify for Medi-Cal, complete the Medi-Cal portion through Covered California or your county.
