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 91020 in a non-facility setting with national GPCI: (1.4 + 7.76 + 0.08) × $33.4009 ≈ $308.62. The same code in a facility setting pays about $308.62 because facility PE RVU (7.76) replaces office PE RVU.
