Post disp fx of sternal end unsp clavicle, 7thK

This code signifies a fracture at the sternal (medial) end of the clavicle, where the bone fragments have shifted backward (posteriorly). The fracture is not healing as expected, indicating a nonunion, and the patient is presenting for follow-up care after initial treatment. The specific side of the clavicle (left or right) is not documented.

Use this code for a patient who has previously been treated for a posterior displaced fracture of the sternal end of an unspecified clavicle and is now returning for subsequent care related to the ongoing nonunion of that fracture. This applies to situations like follow-up appointments, cast changes, or evaluations for further intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies a "subsequent encounter" for the fracture.
• Verify that the fracture is indeed at the "sternal end" and is "posteriorly displaced."
• If the laterality (left or right) of the clavicle is documented, a more specific code should be selected.
