Official Description

Closed treatment of humeral condylar fracture, medial or lateral; with manipulation

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Closed treatment of a humeral condylar fracture, specifically of the medial or lateral condyle, involves a non-surgical approach to address a fracture located at the distal end of the humerus. The humerus, which is the long bone of the upper arm, features two prominent projections known as the medial epicondyle and lateral epicondyle. A condylar fracture refers to a break that occurs in the area where these projections are located, leading to a separation of the medial metaphysis and epicondyle from the main body of the humerus. Such fractures can also extend into the trochlea, which is the part of the humerus that articulates with the ulna, and may involve the articular surface, impacting joint function. This procedure is indicated when there is a fracture of either the medial or lateral condyle, but not both simultaneously. Prior to the treatment, radiographs are obtained to confirm the presence of the fracture. Additionally, a neurovascular examination is conducted to assess the integrity of the nerves and blood vessels surrounding the injury site. In contrast to CPT® Code 24576, which pertains to nondisplaced fractures that do not require manipulation, CPT® Code 24577 is specifically for cases where there is a minimally displaced fracture. In this scenario, the displaced fragments are manually manipulated back into their correct anatomical position, followed by immobilization of the arm using a long arm cast to ensure proper healing.

1. Indications

Closed treatment of a humeral condylar fracture, medial or lateral, is indicated for the following conditions:

  • Fracture of the Medial Condyle A fracture specifically located at the medial condyle of the distal humerus.
  • Fracture of the Lateral Condyle A fracture specifically located at the lateral condyle of the distal humerus.
  • Minimally Displaced Fracture A fracture that is not completely displaced but requires manipulation to restore proper alignment.

2. Procedure

The procedure for closed treatment of a humeral condylar fracture involves several key steps:

  • Step 1: Radiographic Confirmation Initially, radiographs are obtained to confirm the presence and extent of the fracture. This imaging is crucial for determining the appropriate treatment approach and ensuring that the fracture is accurately diagnosed.
  • Step 2: Neurovascular Examination A thorough neurovascular examination is performed to assess the integrity of the nerves and blood vessels in the area surrounding the fracture. This step is essential to rule out any potential complications that could arise from the injury.
  • Step 3: Manual Reduction If the fracture is determined to be minimally displaced, the next step involves manually reducing the fracture fragments. This manipulation is performed to realign the bone fragments to their proper anatomical position, which is critical for optimal healing and function.
  • Step 4: Immobilization Following the successful reduction of the fracture, the arm is immobilized using a long arm cast. This immobilization is necessary to stabilize the fracture site and promote healing by preventing movement that could disrupt the alignment of the bone fragments.

3. Post-Procedure

After the closed treatment procedure, the patient will typically require follow-up visits to monitor the healing process. The immobilization with the long arm cast will remain in place for a specified duration, during which the patient should avoid any activities that could stress the fracture site. Pain management may be addressed as needed, and the patient will be advised on signs of complications, such as increased pain, swelling, or changes in sensation, which should prompt immediate medical attention. Once healing is confirmed through follow-up radiographs, rehabilitation exercises may be recommended to restore range of motion and strength in the affected arm.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
