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 78598 in a non-facility setting with national GPCI: (0.83 + 7.01 + 0.09) × $33.4009 ≈ $264.87. The same code in a facility setting pays about $264.87 because facility PE RVU (7.01) replaces office PE RVU.
