What 29720 covers
This service covers restoring a damaged body spica cast or jacket so it can continue to immobilize the torso and affected body area. It may involve reinforcing or replacing a damaged section while preserving the existing cast. Orthopedic clinicians commonly provide or direct this cast care in an office or other treatment setting when a cast has cracked, softened, or otherwise lost structural integrity.
Select this code when the documented work repairs the existing spica cast or jacket, rather than removing it or changing its shape or access. The note should identify the cast, the damage, and the repair performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur 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 services are not paid, and co-surgeons and team surgery are not permitted.

29720 billing questions
When should 29720 be chosen over cast removal?
Use 29720 when the existing body spica cast or jacket is repaired and remains in use. If the cast is removed, select the applicable removal service instead.
Is opening a cast the same as repairing it?
No. Use the cast-windowing service when the work creates an access opening; 29720 describes repair of damage to the existing body cast or jacket.
How does repair differ from cast wedging?
Repair restores damaged cast material. Wedging changes cast alignment or shape, so report the service that matches the work documented.
Can modifier 50 be reported for repair on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
What documentation supports 29720?
Document the body spica cast or jacket, the damage, and how the existing cast was restored. The record should make clear that the service was repair, not removal, windowing, or wedging.
