San Diego, California: health insurance
San Diego is in San Diego County. Here is what San Diego residents should know about coverage.
Medicaid is a government program that gives free or low-cost health coverage to people with limited income, such as some adults, children, pregnant women, seniors and people with disabilities. Each state runs its own Medicaid program and decides who qualifies. We are an independent insurance agency, and we cannot enroll you in Medicaid or check your Medicaid.

If your income is too high for Medicaid, or you want to compare health plans, call us. We can help with that.

A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).
