Colorectal Head-Spinner


Best answers
Any help would be appreciated with this complex case. It's essentially 44155, but can't be coded as such because it was performed in pieces over three op sessions. It's a bit of a stumper for me; any colorectal experts out there up to a challenge?!?! Here's a summary (the op notes are rather extensive):

Op 1: Resected terminal ileum and all but the sigmoid colon. No anastomosis; pt left in discontinuity intentionally (massive distention, fecal contamination, etc.) with intent to revisit later. Abdomen left open, wound VAC applied.

Op 2 (three days later): Resected sigmoid colon, took core biopsies of rectum.

Op 3 (next day): Resected rectum and did ileostomy (and took out the gallbladder, for good measure!).

Thanks in advance for any and all suggestions!
