Oth fracture of shaft of l humerus, subs for fx w malunion

This code signifies a fracture of the shaft of the left humerus that is currently in a healing phase, but with evidence of malunion. Malunion indicates that the bone has healed in an unsatisfactory position, potentially leading to functional impairment or cosmetic deformity.

Apply this code when a patient presents for follow-up care of a previously diagnosed left humeral shaft fracture that has healed improperly. This includes evaluations for ongoing pain, limited range of motion, or visible deformity due to the malunion. It is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "malunion" and the "left humerus shaft."
• This code is for subsequent encounters, not the initial treatment of the fracture.
• Always review the full encounter documentation to confirm the laterality and the specific type of fracture healing complication.
