CPT code 29345: Long-leg cast, standard cast application2026 Medicare rate & RVUs

Medicare pays $148.97 for 29345 nationally in the office and $91.52 in a hospital or facility. Local office rates run $131.43–$191.75.

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

What 29345 covers

A long-leg cast immobilizes the knee along with the lower leg and foot, typically extending from the upper thigh to the foot. It may be used to stabilize a lower-extremity fracture or protect the leg after treatment of an injury involving the knee or lower leg. The service is performed by a clinician who applies and molds the cast; it may occur in an office, emergency department, or other treatment setting.

Report this code when the long-leg cast application is not included in a separately reported fracture-treatment service. Documentation should identify the treated side, clinical reason for immobilization, and the cast applied. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral application, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. CMS does not pay an assistant at surgery for this service and does not permit co-surgeon or team-surgery billing.
