Billing code 29325: Hip spica castMedicare rate & RVUs

Medicare pays $313.30 for 29325 nationally in the office and $168.34 in a hospital or facility. Local office rates run $274.37–$412.50.

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

What 29325 covers

This service covers applying a hip spica cast that extends over the pelvis and trunk, one full leg, and part of the opposite leg. Orthopedic surgeons and other qualified clinicians use this extent of immobilization when treatment must control the hip and pelvis as well as the injured lower extremity. A common clinical setting is immobilization of a child's femoral fracture when a spica cast is selected.

Choose this code based on the cast's extent, rather than the diagnosis alone; a cast involving only one leg is reported with 29305. The record should identify the treated condition, the need for immobilization, and the cast's actual extent. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
