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 42409 in a non-facility setting with national GPCI: (2.84 + 8.33 + 0.42) × $33.4009 ≈ $387.12. The same code in a facility setting pays about $210.43 because facility PE RVU (3.04) replaces office PE RVU.
