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 42550 in a non-facility setting with national GPCI: (1.22 + 3.06 + 0.12) × $33.4009 ≈ $146.96. The same code in a facility setting pays about $52.11 because facility PE RVU (0.22) replaces office PE RVU.
