About 61557: Multiple-suture craniosynostosis craniectomy
Craniectomy for craniosynostosis involving multiple fused cranial sutures, reported when operative treatment releases more than one affected suture.
This operation treats craniosynostosis in which multiple cranial sutures have fused prematurely. A neurosurgeon, often working in a pediatric craniofacial setting, removes bone along the affected sutures to release restricted skull growth. The operative plan and extent depend on the sutures involved and the child’s skull deformity; this code identifies the multiple-suture craniectomy service rather than surgery limited to one suture.
Report the code when the operative record supports treatment of multiple synostotic sutures by craniectomy. Document the affected sutures, the extent of bone removal, and the procedure performed so the multiple-suture service is clear. The code 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 other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61557 billing questions
How is this code distinguished from 61556?
61557 is for craniectomy involving multiple cranial sutures. Use 61556 when the documented operation is limited to a single cranial suture.
How does this differ from 61550 or 61552?
Those codes describe reconstruction of cranial sutures for craniosynostosis. Choose the code that matches the documented operative approach rather than treating reconstruction and craniectomy as interchangeable.
Can modifier 50 be reported?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this service.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
