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 77778 in a non-facility setting with national GPCI: (8.56 + 18.83 + 0.54) × $33.4009 ≈ $932.89. The same code in a facility setting pays about $932.89 because facility PE RVU (18.83) replaces office PE RVU.
