What 29355 covers

This service covers applying a long-leg cast that extends from the thigh to the toes and is configured to permit walking. Orthopedic surgeons and other clinicians who manage musculoskeletal injuries may apply it in an office or other treatment setting when an injury requires immobilization across the knee and lower leg but the patient can ambulate in the cast. Selected lower-extremity fractures are a typical reason for this form of immobilization.

Report the code when the documented cast spans the thigh to the toes and has a walking configuration; a standard long-leg cast without that feature is distinguished by code 29345. Document the treated side, cast extent, walking design, and clinical reason for immobilization. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. For bilateral application, modifier 50 is paid at 150%. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
