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 88348 in a non-facility setting with national GPCI: (1.47 + 12.72 + 0.12) × $33.4009 ≈ $477.97. The same code in a facility setting pays about $477.97 because facility PE RVU (12.72) replaces office PE RVU.
