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.

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.

Document the treated side, the long-leg cast-brace configuration, and why that form of stabilization was selected. The record should distinguish it from a standard or walker-type cast.

Can both legs be reported?

For bilateral performance, CMS lists modifier 50 and payment at 150%. Document application to both sides.

Does the code include same-day related care?

The code has a 0-day global period, which includes same-day preoperative and postoperative care. Other procedures in the same session are subject to the standard multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

CMS lists a statutory restriction on assistant-at-surgery payment. Co-surgeons and team surgery are not permitted for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
