What 15733 covers
This code covers reconstruction with a muscle, skin-and-muscle, or fascia-and-skin flap moved to a head or neck defect while remaining attached to its named blood supply. Examples include buccinator, facial artery musculomucosal, and submental flaps. Plastic surgeons and head-and-neck surgeons may use these flaps to restore tissue after tumor removal, trauma, or other defects, commonly in an operating room.
Choose the code when the operative report supports the flap’s tissue type, head-and-neck location, and named vascular pedicle; distinguish it from a free flap that requires microvascular transfer. The 90-day global period includes the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose

15733 billing questions
How does this differ from a free flap?
This flap remains attached to its named vascular pedicle during transfer. A free flap is detached and transferred using microvascular anastomosis.
What documentation supports reporting this code?
Document the flap’s tissue composition, head-or-neck recipient site, named vascular pedicle, and transfer into the defect.
Can modifier 50 be used for bilateral work?
No. CMS identifies bilateral adjustment as inappropriate for this code’s descriptor or anatomy.
Is related postoperative care separately reported during the global period?
The 90-day global period includes related postoperative care, as well as the day-before preoperative visit.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is restricted. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
