Unsp nondisp fx of surg nk of l humer, 7thK

This code signifies a fracture of the surgical neck of the left humerus that was initially nondisplaced and whose specific type was not documented. The patient is now in a subsequent phase of treatment, and the fracture has failed to heal properly, resulting in a nonunion.

Apply this code for follow-up encounters where a patient with a previously diagnosed, unspecified, nondisplaced surgical neck fracture of the left humerus is being treated for a confirmed nonunion. This would include scenarios such as ongoing conservative management for nonunion or pre-operative assessment for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the laterality (left humerus) and the specific anatomical site (surgical neck).
• Confirm that the initial fracture was nondisplaced and its specific type was not further specified.
