This peer-reviewed paper in the September 2018 issue of Health Affairs analyzes California dental plans’ medical loss ratios [MLR] reported in California for 2014 and 2015. California passed a law in 2014 requiring dental plans to report MLRs but stopped short of setting minimum thresholds. Len Finocchio and Katrina Connolly found that while millions of Californians were in large-group plans that achieved high MLRs, millions more were in other plans with relatively low MLRs. A legislatively mandated MLR would provide a standardized financial tool and potentially ensure value for dental products. Given the multiplicity of dental products and the varying numbers of covered lives in those products, setting MLR thresholds poses a challenge for stakeholders.
