What 29358 covers
This service covers fitting and applying a long-leg cast brace that extends along the lower extremity from the thigh toward the toes. Orthopedic clinicians use this form of immobilization when the treatment plan calls for a cast-brace configuration; it is distinct from a conventional long-leg cast and a walker-type cast. The code describes the application, not a particular diagnosis or fracture-care service.
Select the code based on the device and extent documented. The record should identify the treated side, the long-leg cast-brace configuration, and the clinical reason for using it. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral reporting, modifier 50 is paid at 150%. When performed with other procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
