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.

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.

29440 billing questions

How is 29440 different from applying a walking cast?

29440 adds a walking support to a cast that is already in place. Use the applicable cast-application code when the service is applying a new walking cast.

Yes. Same-day preoperative and postoperative care is included in the service.

How is modifier 50 handled for bilateral service?

CMS pays a bilateral service reported with modifier 50 at 150%.

What happens when other procedures are performed in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50%. Medicare does not pay an assistant at surgery for 29440, and co-surgeons and team surgery are not permitted.

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.
