Colorectal Surgery & Pelvic Exenteration Scrubber

Colorectal oncology cases face aggressive payer auditing: clearinghouses bundle protective diverting loop ileostomies (44320) into low anterior resections (45119), downcode colonic J-pouch reservoirs to simple colectomy (44145), and reject co-surgeon Modifier -62 claims during multivisceral pelvic exenteration (45126). Audit your operative dictation for bulletproof compliance.

Tool #56 • Surgical Oncology & Colorectal RCM
CPT 45110-45126 • 44320 • CMS NCCI Ch. VII

Colorectal Surgery & Pelvic Exenteration Scrubber

Model total mesorectal excision (TME), multivisceral pelvic exenterations, colonic J-pouch reservoirs, and protective diverting loop ileostomies. Enforces Modifier -62 co-surgeon validation, protects against partial colectomy downcoding, and eliminates fatal NCCI stoma unbundling denials.

Operative note substantiates CPT 45119. Colonic pouch creation is fully reimbursable over simple LAR.

Ref: CPT Coding Guidelines, Digestive System
Separate Incision Stoma Defended (Modifier XE)

Medical necessity verified: Prior radiation (Yes) and ultra-low anastomotic height justify non-integral diversion through separate counter-incision.
