Disp fx of med epicondyl of l humer, subs for fx w nonunion

This code describes a situation where the medial epicondyle of the left humerus has experienced an avulsion fracture, meaning a piece of bone has been pulled away by a tendon or ligament. Crucially, the fracture fragments are not properly aligned (displaced), and the bone has failed to heal after an initial treatment (nonunion). This indicates a persistent lack of bony bridging across the fracture site.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced avulsion fracture of the left humeral medial epicondyle that has not healed. This includes situations where further interventions, such as surgery or prolonged immobilization, are being considered or performed due to the nonunion. It is used when the patient is beyond the initial healing phase and the fracture has failed to unite.

• Verify laterality (left humerus) and the specific fracture type (avulsion of medial epicondyle).
• Ensure documentation clearly states "nonunion" and "displaced" for this specific fracture site.
• This code is for subsequent encounters, not the initial treatment of the fracture.
