How the payment is calculated
Total RVU is work plus practice expense plus malpractice, each adjusted by its GPCI factor, then multiplied by the conversion factor. For 91117 in a non-facility setting with national GPCI: (2.39 + 1.08 + 0.18) × $33.4009 ≈ $121.91. The same code in a facility setting pays about $121.91 because facility PE RVU (1.08) replaces office PE RVU.
