What 29440 covers
This service modifies an existing cast by adding a walking support, such as a walker or walking heel, so the patient can bear weight on the cast. It is typically performed in an orthopedic or podiatry clinic or cast room when a lower-extremity cast is being converted for walking after its initial application.
Report 29440 for the addition to the previously applied cast, not for applying a new walking cast. Documentation should identify the existing cast, the support added, the treated side, and the clinical reason for the modification. 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 the others at 50%. For a bilateral service reported with modifier 50, payment is 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
