California Health Insurers in 2017

Katherine Wilson, Wilson Analytics

In 2017, California health insurers covered 33.1 million enrollees — 27.3 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 the California Health Insurers Enrollment Database (ZIP) — combine 2017 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 2017. Data include detail by market (e.g., individual, large group, Medi-Cal), product (e.g., HMO, PPO), regulator (DMHC and CDI), insurer (e.g., Anthem Blue Cross), and year.



A full report will be available in early 2019. These materials are part of CHCF’s California Health Care Almanac, an online clearinghouse for key data and analyses describing the state’s health care landscape.
