What 29740 covers

Cast wedging modifies an existing cast to change the position or alignment of the underlying limb, often after reassessment of a fracture. The clinician makes a controlled cut in the cast, adjusts the opening or overlap to alter alignment, and secures the cast again. Orthopedic clinicians commonly perform this service during fracture follow-up when the cast can remain in place but its position needs correction.

Report 29740 for the cast adjustment, not for creating a window to reach the skin or repairing a damaged spica cast. Document the reason for the adjustment, the cast modification performed, and the clinical assessment supporting the alignment change. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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 50% multiple procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
