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 58820 in a non-facility setting with national GPCI: (4.58 + 3.7 + 0.81) × $33.4009 ≈ $303.61. The same code in a facility setting pays about $303.61 because facility PE RVU (3.7) replaces office PE RVU.
