Los Angeles — The Los Angeles Business Journal this week released its 2016 Health Insurer List based on member enrollment in L.A. County. This year, L.A. Care Health Plan is the top ranked health insurer with more than 2 million members, which represents a 16% increase in members over a year ago. Based on current membership figures, this makes L.A. Care not only the nation’s largest publicly operated health plan, but also L.A. County’s largest health insurer. The significant increase in members is due, in large part, to the expansion of Medi-Cal coverage under the Affordable Care Act.
