2-part disp fx of surg nk of unsp humer, 7thK

This code signifies a fracture of the surgical neck of the humerus that has broken into two distinct pieces and is no longer in its proper anatomical alignment. Importantly, this code is used when the fracture has failed to heal adequately after an initial treatment, indicating a nonunion. The specific side (left or right) of the humerus is not documented.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed two-part displaced surgical neck humerus fracture that has not united. This includes situations where further interventions, such as revision surgery, bone grafting, or prolonged immobilization, are being considered or performed due to the nonunion. It is also appropriate for monitoring the nonunion.

• Ensure documentation clearly states "nonunion" and "displaced" for a two-part surgical neck fracture.
• Verify that the encounter is subsequent to the initial fracture treatment.
• Confirm that the laterality of the humerus is not specified in the clinical record.
