Oth disp fx of lower end unsp humer, subs for fx w malunion

This code signifies a fracture of the lower part of the humerus that is not specified as to laterality (left or right), has shifted from its normal alignment, and is in the process of healing incorrectly. Malunion indicates that the bone fragments have joined in a deformed position, potentially leading to functional impairment. This specific code is used for follow-up care related to this malunion.

Use this code for a patient presenting for ongoing management of a previously sustained, unspecified distal humeral fracture that has healed in a misaligned fashion. This would include clinic visits for assessment of the malunion, planning for corrective surgery, or monitoring of non-operative management of the malunion. It is appropriate when the initial fracture treatment has concluded, and the focus is now on the complication of malunion.

• Ensure documentation clearly states "malunion" and that the fracture is of the "lower end of humerus."
• Verify that the encounter is for follow-up care related to the malunion, not initial treatment or routine healing.
• Do not use if the laterality (left/right) of the humerus is specified; a more specific code would be available.
