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 91037 in a non-facility setting with national GPCI: (0.95 + 4.59 + 0.07) × $33.4009 ≈ $187.38. The same code in a facility setting pays about $187.38 because facility PE RVU (4.59) replaces office PE RVU.
