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 37766 in a non-facility setting with national GPCI: (5.85 + 7.53 + 1.37) × $33.4009 ≈ $492.66. The same code in a facility setting pays about $301.61 because facility PE RVU (1.81) replaces office PE RVU.
