California runs the nation's largest ACA marketplace — Covered California — with 1.8 million enrollees in 2025. The state expanded Medi-Cal (Medicaid) and now covers nearly 15 million Californians through public programs. Medicare covers 6.8 million Californians, and the state has some of the most competitive Medicare Advantage markets in the country.
California residents turning 65 have two main Medicare paths: Original Medicare (Parts A + B) with an optional Supplement plan, or Medicare Advantage (Part C) from a private carrier. Each path has different costs, network rules, and out-of-pocket limits. The right choice depends on your health needs, preferred doctors, and financial situation.
Missing your Initial Enrollment Period can result in a permanent Part B late enrollment penalty of 10% for every 12 months you delayed. Getting guidance before your 65th birthday — ideally 3 months before — is essential.
