Hello, I'm a new biller and my question is about what ICD to use in this case, The doctor reports "No ulcerations, No polyps, no diverticulosis noted. Biopsies were obtained from ascending colon, transverse colon, descending colon, sigmoid colon and rectum Using cold forceps biopsy and sent for pathology." It's screening, so should I use 45380 with Z12.11,,, any other Dx? for the random biopsies?
