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 45123 in a non-facility setting with national GPCI: (18.39 + 9.25 + 3.28) × $33.4009 ≈ $1,032.76. The same code in a facility setting pays about $1,032.76 because facility PE RVU (9.25) replaces office PE RVU.
