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 31578 in a non-facility setting with national GPCI: (2.37 + 6.38 + 0.36) × $33.4009 ≈ $304.28. The same code in a facility setting pays about $129.26 because facility PE RVU (1.14) replaces office PE RVU.
