Each figure is the median of that hospital's published rates for the procedure's code family under that plan type. "Insured median" is the median of the hospital's commercial-plan rates (PPO, HMO, EPO, POS, ACA marketplace and plans not labelled by type); the headline figure is the median of that column. Hospitals label plan types differently, so compare the Insured median column across hospitals rather than a single plan-type column. "×Medicare" compares to the CMS national outpatient rate. Blank cells mean the hospital's file discloses no dollar rate for that plan type.
