What 29435 covers

This service involves applying a below-knee cast shaped to transfer weight-bearing load through the patellar tendon region rather than directly onto the lower leg. An orthopedic clinician may use this design for selected tibial fractures when protected or progressive weight bearing is part of the plan. The cast is distinct from an ordinary short-leg cast and from a walking cast that does not use the patellar tendon-bearing design.

Report the cast application when that service is separately reportable; cast application is included when the reported fracture-treatment service already includes it. Documentation should identify the treated side, the clinical indication, and the PTB cast design. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and 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.

29435 billing questions

How is a PTB cast different from a short-leg cast?

A PTB cast is shaped to transfer load through the patellar tendon region. Use the short-leg cast code when that specific design is not applied.

Is the cast application separately reported with fracture treatment?

Not when the fracture-treatment service reported already includes cast application. Report this application only when it is separately reportable.

What documentation supports this code?

Document the treated side, indication, and application of a below-knee cast designed to bear through the patellar tendon region.

How does Medicare handle bilateral application?

CMS lists this as a bilateral procedure: modifier 50 is paid at 150%.

What happens when this is performed with another procedure?

For procedures performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple procedure reduction.

Can an assistant, co-surgeon, or surgical team be reported?

Assistant-at-surgery payment is restricted for this service. 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.
