My doc performed ex. lap, LOA, right hemicolectomy, chole with ioc and CBD exploration, placement of T-tube, and take down of cholecystocolonic fistula.

I have the codes for the right hemicolectomy (44160), chole with IOC and CBD exploration (47610), but need help with the take down of the fistula. Would it be 44650? (Closure enteroenteric or enterocolic fistula). I cannot find an exact one that he performed.

Thanks in advance for your help!
