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 77334 in a non-facility setting with national GPCI: (1.12 + 2.6 + 0.06) × $33.4009 ≈ $126.26. The same code in a facility setting pays about $126.26 because facility PE RVU (2.6) replaces office PE RVU.
