Unsp fx lower end of unsp humerus, subs for fx w malunion

This code signifies a previously sustained fracture of the distal humerus that has healed in a misaligned position (malunion). It indicates that the patient is currently presenting for follow-up care related to this malunited fracture, not for the initial injury or a new fracture. The specific side (left/right) and laterality are not documented.

Use this code for patients presenting for ongoing management of a malunited distal humerus fracture after the initial treatment period. This includes follow-up appointments, physical therapy evaluations, or imaging studies to assess the malunion. It is appropriate when the documentation confirms a prior fracture and subsequent malunion without specifying the exact location on the lower end of the humerus.

• Ensure documentation clearly states "malunion" and that the encounter is for follow-up care of a previously fractured humerus.
• Verify that the fracture location is described as the "lower end" or "distal" humerus, and that laterality is unspecified.
• Do not use this code for initial fracture treatment, nonunion, or if the specific laterality (left/right) is documented.
