Feb. 2018 Edition — California Health Insurance Enrollment

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.

This set of resources — California Health Insurers, Enrollment: Quick Reference Guide (PDF) and California Health Insurers Enrollment Database (ZIP) (published 2018) — combines 2016 enrollment data from California’s two health insurance regulators, the Department of Managed Health Care (DMHC) and the California Department of Insurance (CDI). Data are available from 2012, the first year of state-mandated enrollment reporting, through 2016. Data include information by market (e.g., individual, large group, Medi-Cal), product (e.g., HMO, PPO), regulator (DMHC and CDI), insurer (e.g., Anthem Blue Cross, Kaiser), and year.

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.

The quick reference guide and data files are available for download below.
