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 37279 in a non-facility setting with national GPCI: (4 + 133.99 + 0.81) × $33.4009 ≈ $4,636.04. The same code in a facility setting pays about $181.7 because facility PE RVU (0.63) replaces office PE RVU.
