Oth nondisp fx of upr end unsp humer, subs for fx w malunion

This code signifies a non-displaced fracture of the upper humerus that is currently healing with an unsatisfactory alignment (malunion). The injury itself is not new, and the patient is presenting for follow-up care related to this healing complication.

Use this code when a patient with a previously diagnosed and treated non-displaced fracture of the upper humerus presents with evidence of malunion during a subsequent encounter. This applies to situations where the fracture fragments have healed in a deformed or misaligned position, requiring ongoing management or evaluation.

• Ensure documentation clearly states "malunion" and specifies the "upper end of humerus" and "nondisplaced" nature of the original fracture.
• This code is for subsequent encounters only; do not use for the initial treatment of the fracture.
• Always review the medical record for laterality (left, right, or unspecified) and the specific type of fracture (e.g., surgical neck, anatomical neck) if available, as more specific codes may exist.
