What 49906 covers
Code 49906 identifies a free omental flap transfer in which the omentum is moved to a recipient site and connected to recipient blood vessels through microvascular anastomosis. The distinguishing feature is the free transfer with microvascular connection; 49904 and 49905 describe other omental flap approaches, respectively extra-abdominal and intra-abdominal. The operating surgeon reports this reconstructive procedure when the transferred tissue is omentum and the flap is microsurgically revascularized.
Medicare assigns status C: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The procedure has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. Standard multiple-procedure reduction applies when procedures are performed in the same session. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
