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 88361 in a non-facility setting with national GPCI: (0.93 + 2.48 + 0.02) × $33.4009 ≈ $114.57. The same code in a facility setting pays about $114.57 because facility PE RVU (2.48) replaces office PE RVU.
