Per Capita Medicare Inflation in the Last Decade: Unit Cost Increases Offset by Reduced Utilization.

Dartmouth College has determined that analyses of publicly available data are not considered to be human subjects research (CPHS00028121).

Among the commercially insured, per capita medical expenditure growth has been fueled by unit price inflation. Though attenuated by reduced per capita utilization (2011–2017),1 unit price inflation has driven overall inflation, being substantially higher for hospital than for physician services (2007–2014).2 While per capita health care spending growth has been higher for the commercially insured than for those insured by Medicare,3 evaluation of the relative contributions of utilization and unit price inflation to overall per capita Medicare fee-for-service expenditure inflation has not been conducted. We sought to complete such an analysis.
