Health insurance giant Aetna Inc. has launched a new plan geared for Southern California that includes collaborations with Los Angeles County hospital systems.

The Hartford, Conn.-based insurance company announced Aug. 13 it was introducing an Aetna Whole Health-Southern California plan, with access to four networks comprised of 51 hospitals, 122 urgent care clinics and 10,000 doctors and specialists in five counties.

The plan includes new collaborations with MemorialCare Health System, which covers Long Beach and Orange County, and Providence Health & Services, which covers the South Bay to the San Fernando Valley.

The value-based insurance plan, now available from Aetna to self-insured employers, also includes accountable care networks based in the Inland Empire and in San Diego.
