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 64635 in a non-facility setting with national GPCI: (3.24 + 10.39 + 0.29) × $33.4009 ≈ $464.94. The same code in a facility setting pays about $173.02 because facility PE RVU (1.65) replaces office PE RVU.
