About 21705: Sternocleidomastoid muscle resection
Reports resection of sternocleidomastoid muscle, typically to address congenital muscular torticollis when muscle excision is performed.
This open operation removes sternocleidomastoid muscle tissue to release persistent restriction, most commonly in a patient with congenital muscular torticollis. The surgeon works through the neck to resect the involved muscle; the operative report should identify the muscle treated and describe the excision. The service is generally performed in an operating room rather than an office setting.
Select this code when the documented procedure is muscle resection, not simply division or release, and distinguish it from repair or reconstruction of a congenital muscle abnormality. The operative note should support the indication, side, extent of resection, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral reporting with modifier 50, payment is at 150%. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

21705 billing questions
How does 21705 differ from 21700?
Use 21705 for resection of sternocleidomastoid muscle tissue. Code 21700 describes division of the muscle, so the operative technique documented determines the choice.
What documentation supports reporting 21705?
The operative report should identify the sternocleidomastoid muscle, the side, the reason for surgery, and the resection performed. A diagnosis of torticollis alone does not establish that muscle resection occurred.
Can 21705 be reported bilaterally?
CMS identifies this as a bilateral procedure; report modifier 50 when the procedure is performed bilaterally. Payment is at 150%.
Are postoperative visits included?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon be paid for 21705?
CMS indicates that an assistant at surgery may be paid. Co-surgeons and team surgery are not permitted for this code.
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 the other procedures are paid at 50%.
