CPT code 29305: Hip spica cast, one leg2026 Medicare rate & RVUs

Medicare pays $284.58 for 29305 nationally in the office and $151.64 in a hospital or facility. Local office rates run $248.95–$375.69.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
