About 21740: Open sternal reconstruction for deformity
Open sternal reconstruction reshapes or rebuilds the sternum to correct a congenital or acquired chest-wall deformity, such as pectus deformity.
This service involves surgically reconstructing the sternum to correct a congenital or acquired deformity. It is typically performed by a thoracic surgeon in an operating room. Open reconstruction may be selected for a chest-wall deformity such as pectus excavatum or carinatum; the operative approach and extent of reconstruction distinguish it from minimally invasive repair techniques.
Report the code when the surgeon’s work reconstructs the sternum, not simply closes a separated median sternotomy. The operative report should identify the deformity, the anatomic problem addressed, and the reconstruction performed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

21740 billing questions
How does this differ from the minimally invasive pectus repair codes?
This code describes open sternal reconstruction for a deformity. The minimally invasive pectus codes distinguish repair performed without thoracoscopy from repair performed with thoracoscopy.
Should this be reported for closure of a separated median sternotomy?
No. Code 21750 describes closure of median sternotomy separation; choose based on the documented procedure and indication rather than the shared sternal anatomy.
Can modifier 50 be used for bilateral reconstruction?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
What documentation supports reporting this code?
The operative report should describe the congenital or acquired sternal deformity, the reconstruction performed, and the extent of the surgical work.
How does the 90-day global period affect postoperative reporting?
The global period includes the day-before preoperative visit and 90 days of related postoperative care. Those related services are included in the surgical global package.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
