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 78597 in a non-facility setting with national GPCI: (0.73 + 4.6 + 0.06) × $33.4009 ≈ $180.03. The same code in a facility setting pays about $180.03 because facility PE RVU (4.6) replaces office PE RVU.
