Summary & Overview
CPT 24538: Percutaneous Fixation of Humeral Supracondylar Fracture
CPT code 24538 denotes percutaneous pinning or wiring for fractures of the humerus through or above a condyle without extension between condyles. This operative technique is a common orthopedic procedure for stabilizing displaced supracondylar and distal humeral fractures, enabling bone alignment with minimally invasive hardware placement. Nationally, the code matters for surgical scheduling, reimbursement policy, and quality tracking for upper-extremity fracture care.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and payment nuances for 24538 often affect site-of-service decisions (inpatient vs outpatient), bundling with related fracture care services, and claims adjudication for surgical orthopedic care.
Readers will learn the clinical context of the code, expected service setting, and which payers are commonly involved. The publication provides benchmarks for utilization and payment (where available), notes common billing patterns for percutaneous humeral fixation, and summarizes relevant policy considerations that influence coding and claims processing. Data not available in the input will be indicated as such in the detailed sections.
Billing Code Overview
CPT code 24538 describes a percutaneous fixation of a humeral supracondylar fracture. The procedure involves inserting pins or wires through the skin and into the humerus to reduce and stabilize a fracture that extends through or above one condyle but does not cross between condyles.
Service Type: Percutaneous fracture fixation
Typical Site of Service: Operating room or procedure suite in an acute care hospital or outpatient surgical center
Clinical & Coding Specifications
Clinical Context
A 9-year-old male falls from playground equipment and presents to the emergency department with acute right elbow pain, swelling, and inability to move the elbow. Radiographs demonstrate a displaced supracondylar fracture of the distal humerus without intra-articular extension between the condyles. After initial neurovascular assessment and closed reduction attempt in the ED, orthopedic surgery performs a percutaneous pinning procedure under general anesthesia in the operating room. The surgeon achieves closed reduction and inserts multiple smooth Kirschner wires percutaneously across the fracture to maintain alignment. Postoperative workflow includes neurovascular checks, immobilization in a posterior splint or cast, radiographic confirmation of pin position, discharge instructions for pin-site care, and outpatient follow-up in 1 week for wound check and radiographs, with hardware removal typically 3–6 weeks later when fracture healing is adequate.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Principal physician of record | When the reporting surgeon is the primary attending responsible for the procedure. |
22 | Increased procedural services | When additional work beyond typical is required (extensive soft-tissue release or prolonged time). |
