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 31090 in a non-facility setting with national GPCI: (10.89 + 17.8 + 1.59) × $33.4009 ≈ $1,011.38. The same code in a facility setting pays about $1,011.38 because facility PE RVU (17.8) replaces office PE RVU.
