What 29705 covers
This service covers removing a full arm or leg cast or bivalving it by cutting through the cast and padding to separate it into two sides. Orthopedic clinicians may perform it during fracture follow-up, when immobilization is changing, or when pressure or swelling calls for cast release. It can also allow access to examine the underlying area. The code is for a full arm or leg cast, rather than a gauntlet or boot cast or a shoulder or hip spica.
Select 29705 based on the cast type and the work performed. Document the body site, whether the cast was removed or bivalved, and the clinical reason. A 0-day global period means same-day preoperative and postoperative care is included. In a session with multiple procedures, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 for a bilateral procedure is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
