Katherine Wilson

California's insurance market is experiencing significant change as a result of health reform and the millions who became newly eligible for public insurance and private subsidies.

A quick reference guide with 2014 enrollment data points to large shifts in both Medi-Cal and individual coverage levels due to the Affordable Care Act (ACA). The report California Health Insurers: Brink of Change provides a snapshot of the insurance market in California at the end of 2013, just before the major provisions ACA took effect.

Data from the Department of Managed Health Care (DMHC), the California Department of Insurance (CDI), and other sources were used to examine market share, enrollment, financial performance, premiums, public coverage, and consumer satisfaction.

Key findings include:

  • Health insurance was a $123-billion business in California in 2013, with six carriers accounting for more than three-fourths of all revenues and most insurers operating in the black.
  • In 2013, enrollment shifts were small, except in the pre-ACA individual market.
  • State and federal policy actions brought significant growth to Medi-Cal managed care — about 2.8 million enrollees, a 58% increase in the 18 months ending in June 2014.
  • Covered California enrolled 1.4 million individuals in health insurance plans through 11 carriers in the first enrollment period ending March 31, 2014.
  • Product choice differed by market, with only 20% of individuals enrolled in HMOs and 79% of large group enrollees in HMOs in 2013. This could change in 2014 as the ACA implements sliding-scale premium subsidies and mandates freedom for individual enrollees to choose their product and insurer.
