Los Angeles & Southern California is one of the California regions where the Medicare Advantage lineup has its own local character. This guide covers the carriers active here, how California's Medigap rules apply, and what to check before you choose, from a licensed independent broker.
Los Angeles County is one of the deepest Medicare Advantage markets in the country, with a huge, diverse population and heavy competition among carriers. Kaiser Permanente is a major presence, and SCAN, Health Net, Alignment, Anthem Blue Cross, and Blue Shield of California all compete hard on $0-premium plans and extras. The volume of plans is a blessing and a curse: there are strong options, but also aggressive marketing, so verifying that your doctors and medications are actually covered matters more here than almost anywhere.
Medigap rules are set at the state level, not the regional level, so the same California rules apply across Los Angeles & Southern California. California falls into this bucket: birthday rule state. For the full explanation of what that means for buying and switching a supplement, see our California Medicare guide and our guide to Plan G vs Plan N. Verify the current California rules before you rely on a specific window.
