In my office we have an unusual situation and are unsure of what the best way to bill the claim is. Dr performs exp lap, does extensive lysis of adhesions (nearly 2hrs) small bowel resection is performed, due to ischemia no anastomosis was done. Dr went back to OR following day, performed additional sm bowel resection and anastomosis. How can we bill first days services so that he gets paid for wk done? lysis of adhesions would be bundled with 44120, but the majority of the work was done here. The sm bowel resection wasn't complete so we will have to use mod 52 there. Any advice?
