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 45121 in a non-facility setting with national GPCI: (28.35 + 12.87 + 7.59) × $33.4009 ≈ $1,630.3. The same code in a facility setting pays about $1,630.3 because facility PE RVU (12.87) replaces office PE RVU.
