Unsp disp fx of surg nk of unsp humer, 7thK

This code signifies a fracture of the surgical neck of the humerus that is not in its proper anatomical alignment, where the specific side (left or right) is unknown. The fracture has failed to heal properly after an initial treatment, and the patient is receiving ongoing care for this complication.

This code is appropriate for follow-up encounters where a patient is being treated for a nonunion of an unspecified displaced surgical neck humerus fracture. This includes situations where further surgical intervention, casting, or other non-operative management is being provided specifically to address the nonunion.

• Ensure documentation clearly states "nonunion" as the reason for the subsequent encounter.
• Verify that the laterality of the fracture (left or right) is truly unspecified in the medical record before using this code.
• This code requires an additional code to specify the type of nonunion, if known (e.g., M84.4- for nonunion of fracture).
