We conducted a retrospective observational cohort study of abortion claims data in the California Medicaid program (Medi-Cal). We obtained data on all abortions covered by the fee-for-service (FFS) Medi-Cal program in 2011 and 2012 from California’s Department of Health Care Services (DHCS). The study was approved by the institutional review boards of the University of California, San Francisco and the California Health and Human Services Agency.
