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 93978 in a non-facility setting with national GPCI: (0.78 + 4.48 + 0.14) × $33.4009 ≈ $180.36. The same code in a facility setting pays about $180.36 because facility PE RVU (4.48) replaces office PE RVU.
