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 45330 in a non-facility setting with national GPCI: (0.82 + 5.5 + 0.12) × $33.4009 ≈ $215.1. The same code in a facility setting pays about $53.78 because facility PE RVU (0.67) replaces office PE RVU.
