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 61598 in a non-facility setting with national GPCI: (35.62 + 34.6 + 15.04) × $33.4009 ≈ $2,847.76. The same code in a facility setting pays about $2,847.76 because facility PE RVU (34.6) replaces office PE RVU.
