Question: What diagnosis should I code for a postpolypectomy bleed? I have been using 998.11. Does anyone use 997.4? Arkansas Subscriber Answer: Yes, the correct code for post-operative bleeding is 998.11 (Hemorrhage or hematoma or seroma complicating a procedure; hemorrhage complicating a procedure). You would code 997.4 (Digestive system complications) for other complications, such as intestinal anastomosis, where formerly distant sections of the intestine have been surgically joined.
