Summary & Overview
CPT 29126: Dynamic (Hinged) Lower Arm Splint, Elbow to Palm
CPT code 29126 describes the application of a dynamic (hinged) splint to the lower arm extending from the elbow to the palm to stretch a stiff joint and improve range of motion after surgery or injury. The service is clinically relevant for postoperative rehabilitation, fracture care, and management of chronic neurologic or orthopedic flexion contractures. Nationally, this code supports care pathways that aim to restore function and prevent long-term disability by providing targeted joint mobilization through orthotic devices.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical sites of service, comparisons to related splinting codes, and context on coding relationships for fracture and post-surgical encounters. The publication highlights how 29126 fits into episodes of musculoskeletal care, common clinical scenarios where the service is used (e.g., distal radius fractures, hand fractures, postoperative stiffness), and links to relevant ICD-10 diagnoses for those scenarios.
This summary supplies clinicians, billing staff, and policy analysts with the essential clinical description, payer coverage scope, and related code context needed to identify when CPT code 29126 is applicable. Data not available in the input.
Billing Code Overview
CPT code 29126 describes the application of a dynamic (hinged) splint to the lower arm from the elbow to the palm. The device is applied to stretch a stiff joint and improve range of motion following a surgical procedure or injury, and it can also be used to address flexion contractures in chronic neurologic or orthopedic conditions.
Service Type: Splint application / Orthotic management
Typical Site of Service: Hospital outpatient department, ambulatory surgery center, emergency department, or orthopedic clinic
Clinical & Coding Specifications
Clinical Context
A 36-year-old patient presents to an orthopaedic clinic two weeks after open reduction and internal fixation of a distal radius fracture of the right wrist. The surgical team documents restricted wrist extension and a developing flexion contracture at the wrist joint despite early supervised therapy. The orthopaedic surgeon applies a dynamic (hinged) lower arm splint extending from the elbow to the palm to provide continuous low-load stretch across the wrist joint, facilitate gradual extension, and improve passive range of motion while protecting the surgical repair. The procedure is performed in the outpatient orthopaedic procedure room. The clinician documents baseline range of motion, splint settings (hinge tension and stop limits), patient education on wear schedule and skin checks, and plan for follow-up adjustment in 1–2 weeks.
Coding Specifications
| Modifier | Description | When to Use |
