Disp fx of medial condyle of l humer, subs for fx w malunion

This code signifies a fracture of the inner bony prominence at the lower end of the left upper arm bone that has healed incorrectly. The fracture fragments are no longer in their anatomical alignment, resulting in a deformity or functional impairment. This specific code is used when the patient is receiving follow-up care for this malunion.

This code is appropriate for encounters where a patient is being treated for complications arising from a previously sustained, displaced medial condyle fracture of the left humerus that has healed in a misaligned position. This includes visits for evaluation, further imaging, or planning for corrective procedures related to the malunion. It would not be used for the initial treatment of the acute fracture or for a fracture that has healed correctly.

• Ensure documentation clearly states "malunion" and specifies the left humerus and medial condyle.
• Verify the encounter is for follow-up care related to the malunion, not the initial fracture treatment.
• Distinguish from nonunion (S42.462N), which indicates a complete failure of bone healing.
