Displaced unsp fx unsp lesser toe(s), subs for fx w malunion

This code signifies a follow-up encounter for a fracture of an unspecified lesser toe that has healed incorrectly, resulting in a malunion. The initial fracture was displaced, and the specific toe involved is not documented.

This code is appropriate when a patient presents for ongoing management or evaluation of a previously sustained, displaced lesser toe fracture that has healed in an abnormal alignment. It indicates that the fracture is no longer acute but has developed a complication of malunion.

• Ensure documentation clearly states "malunion" and that the encounter is for follow-up care of the fracture.
• Verify that the toe involved is indeed a "lesser toe" (i.e., not the great toe) and that the specific toe is unspecified.
• Confirm the original fracture was displaced; if not, a different code for non-displaced malunion would be appropriate.
