What 29085 covers
CPT 29085 represents application of a gauntlet-style cast that covers the hand and lower forearm, leaving the elbow free. It is used when an injury requires immobilization across the wrist and hand, such as selected carpal or metacarpal injuries. Orthopedic clinicians commonly apply this cast in office, emergency, or facility settings. The coverage distinguishes it from a cast that extends from below the elbow to the hand and from a cast limited to a finger.
Select the code from the cast’s extent and configuration, not the diagnosis alone. Document the treated side, the areas immobilized, and why this cast was used; replacement of the cast is included in the service. When cast application is part of fracture treatment that already includes it, do not separately report 29085. The 0-day global includes same-day preoperative and postoperative care. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 applies to bilateral performance, paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
