Sonoma residents in Sonoma County have access to plans from Blue Cross Blue Shield, UnitedHealthcare, Ambetter, Cigna, Oscar Health, and Molina Healthcare through the ACA Marketplace and as off-marketplace private plans.

Health insurance premiums in Sonoma depend on your age, plan type, and whether you qualify for ACA subsidies. Many Sonoma residents who qualify for premium tax credits pay $0–$100/month for a Silver plan. Without subsidies, individual premiums typically range from $300–$700/month depending on age and plan tier. A licensed CA agent will calculate your exact subsidy amount for free.
Outside of the ACA Open Enrollment Period (November 1–January 15), you can still get coverage if you have a qualifying life event — such as losing a job, getting married, having a baby, or losing other coverage. This triggers a 60-day Special Enrollment Period. A licensed CA agent can confirm whether you qualify and help you enroll quickly.
