Patient had a total colectomy with transection of the recto-sigmoid junction, creation of Brook ileostomy and extensive lysis of adhesions. During the post-op period the patient returned for follow-up the discussion of patient's inability to care for his ileostomy and his which a reversal. After a lengthy discussion it was agreed that the surgoen would perform an the reversal, and that due to the patient's post-op complications from gallstones a laparoscopic cholecystectomy would also be performed. My gut feeling is this is simply a post-op visit. The doctor wishes to bill and E/M code. If coding an E/M what modifiers should be used? 24 seems inappropriate because the reason for visit is directly related to the original surgery. Any feedback would be appreciated.
