What 49905 covers
49905 captures the surgeon’s additional work of mobilizing and positioning omental tissue as a flap that remains inside the abdominal cavity, such as to cover or reinforce an intra-abdominal defect or support repair of an intra-abdominal fistula. It is performed during an abdominal operation, typically by a general or colorectal surgeon in an operating room.
Report 49905 only with a qualifying primary procedure; it is not a standalone service. Select it when the flap is placed intra-abdominally, rather than carried outside the abdomen or transferred as a free flap with microvascular anastomosis. The operative report should identify the omentum used, its mobilization and final placement, the target or defect addressed, and the primary operation. CMS classifies 49905 as an add-on code and pays it within the primary procedure’s global period.
