In 2016, California health insurers covered 32.6 million enrollees — 27 million were enrolled in commercial coverage or public managed care and 5.7 million were enrolled through administrative services only (ASO) arrangements for self-insured employers. Commercial enrollment consists of small group, large group, and individual enrollment.
Insurers in California provide coverage to both public managed care and commercial enrollees. In 2016, the 14.1 million commercial insurance enrollees had either enrolled in group coverage through their employer or had purchased coverage individually; more than 50% of individually purchased insurance was bought through Covered California. California insurers also covered 12.8 million public managed care enrollees. Insurers provided ASO for 5.7 million enrollees whose employers were self-insured.
Insurers differ by size and by the markets they serve. Kaiser had the most enrollees, the majority of whom were in the large group market. Anthem Blue Cross had the most ASO enrollees. The largest insurers included two county-based health plans, L.A. Care and Inland Empire Health Plan, which cover public managed care enrollees.
