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 31000 in a non-facility setting with national GPCI: (1.17 + 4.3 + 0.16) × $33.4009 ≈ $188.05. The same code in a facility setting pays about $102.21 because facility PE RVU (1.73) replaces office PE RVU.
