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 77431 in a non-facility setting with national GPCI: (1.76 + 1.29 + 0.14) × $33.4009 ≈ $106.55. The same code in a facility setting pays about $106.55 because facility PE RVU (1.29) replaces office PE RVU.
