Disp fx of medial epicondyl of unsp humerus, init for opn fx

This code signifies a fracture where a piece of bone has been pulled away from the main bone by a tendon or ligament (avulsion), specifically affecting the medial epicondyle of the humerus. The fracture is displaced, meaning the bone fragments are not properly aligned, and the injury involves an open wound communicating with the fracture site.

This code is appropriate for the initial treatment of an open avulsion fracture of the medial epicondyle, regardless of which arm is affected. It is used when the patient presents for the first time for definitive care of this specific injury.

• Ensure documentation clearly specifies "open fracture" and "displaced" for accurate code assignment.
• Do not use this code for subsequent encounters or for non-union/malunion; separate codes exist for those scenarios.
• Laterality (left or right) is unspecified in this particular code, so use it when the medical record does not specify the affected arm.
