Summary & Overview
CPT 29126: Dynamic Short Arm Splint Application
Headline: CPT 29126: Dynamic Short Arm Splint Application Streamlines Orthopedic Immobilization
Lead: CPT 29126 documents the application of a dynamic short arm splint (forearm to hand), a common orthopedic procedure for managing fractures and soft-tissue injuries of the forearm and hand. This code matters nationally because it captures a frequently used, non-operative stabilization technique that affects outpatient orthopedic workflows, supply use, and reimbursement policies.
What this code represents and why it matters: CPT 29126 is used to bill for fitting a dynamic short arm splint that stabilizes the forearm and hand while permitting controlled movement. Accurate use of this code supports clinical documentation, care coordination, and appropriate payment for splinting services provided in ambulatory settings.
Key payers covered: The analysis addresses major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication outlines clinical context for splint use, coding distinctions between short and long arm splints, common documentation expectations, and how CPT 29126 is positioned relative to related splinting codes. It highlights typical sites of service and the role of the code in outpatient orthopedic pathways. Where input data is incomplete for specific operational metrics, the text notes "Data not available in the input."
CPT Code Overview
CPT 29126 describes the application of a short arm splint (forearm to hand); dynamic. This procedure is classified under Surgical — Musculoskeletal (Orthopedic) services and typically occurs in an outpatient hospital or physician office setting (for example, POS 11). The code represents fitting and applying a short arm splint designed to provide stabilization while allowing controlled motion as clinically indicated.
Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient orthopaedic clinic or emergency department after wrist or hand trauma with pain, swelling, and suspected distal radius or hand fracture. After clinical evaluation and plain radiographs confirm a nonoperative or initially managed fracture (e.g., closed distal radius or hand fracture, or stress fracture), the treating orthopaedic surgeon, orthopaedic trauma physician, or emergency medicine physician applies a dynamic short arm splint (forearm to hand) to immobilize and permit controlled motion as indicated. The patient is instructed on splint care, activity restrictions, and follow-up for radiographic reassessment and definitive management if needed.

Modifiers:
-
LT: Indicates the procedure was performed on the left side. Use when the dynamic short arm splint is applied to the left upper extremity. -
RT: Indicates the procedure was performed on the right side. Use when the dynamic short arm splint is applied to the right upper extremity. -

Related CPT Codes
| CPT Code | Description | Relationship to 29126 |
|---|---|---|
29125 | Application of short arm splint (forearm to hand) | Alternative or lesser-service code: 29125 describes application of a short arm splint without the dynamic component and may be used when a static short arm splint is applied instead of a dynamic splint. |
29105 | Application of long arm splint (shoulder to hand) | Alternative/adjacent service: 29105 is used when immobilization requires a long arm splint (shoulder to hand) rather than a short arm splint; used in different clinical scenarios or when more proximal immobilization is indicated. |
Common pairing or sequencing: In a clinical workflow, a short arm splint code (29125 or 29126) is used at initial immobilization. 29105 is used when a long arm splint is indicated instead. These codes are alternatives based on the type and extent of immobilization required.
National Reimbursement Benchmarks
Medicare's mean allowed rate for CPT 29126 ($88.61) is slightly below the BUCA national average commercial mean ($90.66), indicating commercial averages are modestly higher than Medicare for this code. The spread between Medicare and BUCA is small in absolute dollar terms, with BUCA exceeding Medicare by $2.05.
Rate dispersion varies across payers. Cigna and UnitedHealth Group show the widest interquartile ranges (P75−P25), indicating greater variability in allowed rates: Cigna's range is $65.00 and UnitedHealth Group's range is $65.71. Aetna displays one of the tightest distributions with a range of $23.33. Medicare's distribution is also relatively tight with a range of $10.00.
