2025 CPT code 24400
(Active) Effective Date: N/A Revision Date: N/A Surgery - Repair, Revision, and/or Reconstruction Procedures on the Humerus (Upper Arm) and Elbow Musculoskeletal System Feed
Osteotomy of the humerus, with or without internal fixation.
Modifiers may be applicable depending on the specific circumstances of the procedure, such as modifier 51 (multiple procedures), 59 (distinct procedural service), 76 (repeat procedure), or others as clinically indicated.
Medical necessity for 24400 is established by the presence of a significant deformity, fracture, or malunion of the humerus that is causing functional impairment or pain. This impairment needs correction to restore normal anatomy and function.Documentation should clearly demonstrate the medical need and justify the procedure.
The orthopedic surgeon is responsible for performing the osteotomy, including incision, bone cutting, realignment, fixation (if necessary), wound closure, and post-operative care. Anesthesiologist provides anesthesia.Other staff, like surgical nurses and technicians, assist as needed.

- Musculoskeletal System; Repair, Revision, and/or Reconstruction Procedures on the Humerus (Upper Arm) and Elbow
In simple words: The doctor cuts the bone in the upper arm (humerus) to correct a problem such as a broken bone or birth defect.They may use metal plates or screws to hold the bone in place while it heals.
This code encompasses surgical procedures involving an osteotomy of the humerus, the bone of the upper arm.The procedure may include the cutting and realignment of the bone to correct deformities, fractures, or malunions. Internal fixation, such as the use of plates, screws, or other implants to stabilize the bone after the osteotomy, may also be performed as part of this procedure.The specific surgical approach and techniques utilized will vary depending on the individual patient's anatomy and the nature of the condition being addressed.
Example 1: A patient presents with a congenital deformity of the humerus causing limited external rotation.An osteotomy is performed to correct the alignment, and internal fixation is used to stabilize the bone., A patient suffers a displaced humeral fracture that is treated with an osteotomy and internal fixation using a plate and screws. This stabilizes the fracture while allowing for proper healing., A patient has a malunion of a previous humerus fracture, resulting in deformity and pain.An osteotomy and internal fixation are performed to correct the malunion and improve function.
* Preoperative diagnosis and imaging studies (x-rays, CT scans) demonstrating the need for the osteotomy.* Operative report detailing the surgical technique, including the type of osteotomy performed, any internal fixation used, and the amount of bone resected.* Postoperative x-rays to confirm bone alignment and the stability of the internal fixation.* Documentation of any complications, such as infection or non-union.* Detailed notes regarding the patient’s progress, including pain management and physical therapy.
** This code may be used for both open and closed procedures. The selection of additional codes (e.g., for internal fixation devices) depends on the specific materials and techniques used during the surgery. Always adhere to the most current CPT coding guidelines.
