Clinics, medical groups, and serving areas

Start from a city. This directory relates named medical groups and clinic locations to the Los Angeles County city guides they serve. It is not a provider directory and not a network list.

A hospital, doctor, medical group, or pharmacy being nearby does not mean it participates in a particular Medicare Advantage network. Original Medicare acceptance is not the same as being in a given plan’s network. Confirm the exact location, physician, medical group, and plan with the office and on Medicare.gov.

Last reviewed September 21, 2026. Serving areas are geographic footprints — not Medicare Advantage service areas and not a network.

Medical groups and IPAs (6)

Medical group

Optum

A large regional medical group. Some offices still show a HealthCare Partners history. Affiliation on a sign is not the same as an exact Medicare Advantage contract. Confirm the physician, location, and plan.

Integrated system

Kaiser Permanente

An integrated system: the medical group, hospitals, and plan generally stay inside Kaiser. That is a different structure from assembling an independent PCP, IPA, and hospital. Neither model is automatically better.
