What 29305 covers

This service covers applying a hip spica cast that stabilizes the pelvis and trunk along with one lower extremity. Orthopedic clinicians commonly use this immobilization for a child with a femoral shaft fracture or after hip reduction when the treatment plan requires the hip and one leg to remain immobilized. The cast is applied in settings equipped to provide the required positioning and casting care.

Report this code for the one-leg cast configuration, not simply because one leg is injured. The record should support the clinical reason for immobilization and show the cast’s extent; use the applicable sibling code when the cast includes more of the opposite leg. Same-day preoperative and postoperative care is included in the 0-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; 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.

29305 billing questions

How is this code distinguished from 29325?

This code describes a hip spica cast involving one leg. Code 29325 is the sibling for a cast involving one and one-half legs; select according to the cast configuration documented.

Can modifier 50 be used when both hips or legs are treated?

No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy. Report the cast configuration that was actually applied.

What same-day care is included?

The 0-day global period includes same-day preoperative and postoperative care. The CMS multiple-procedure reduction may apply when other procedures are performed in the same session.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

What documentation supports reporting this code?

Document the indication for immobilization, the clinical treatment plan, and that the hip spica cast encompasses the trunk and one leg. The cast extent supports choosing this code rather than its one-and-one-half-leg sibling.

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.
