Disp fx of post pro of left talus, subs for fx w malunion

This code signifies a fracture of the posterior process of the left talus that has healed incorrectly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not properly aligned at the time of the original injury. This diagnosis indicates that the patient is presenting for follow-up care related to this improperly healed fracture.

This code is appropriate for subsequent encounters where a patient is being treated for complications arising from a malunited displaced fracture of the left talar posterior process. This includes visits for assessment of ongoing pain, functional limitations, or consideration of corrective procedures due to the malunion. It should be used when the initial fracture treatment has concluded, but the fracture has not healed correctly.

• Ensure documentation clearly states "malunion" and specifies the "posterior process" of the "left talus."
• Verify that the encounter is "subsequent" and not for the initial treatment or routine follow-up of a healing fracture.
• Confirm the fracture was initially "displaced" as this is a specific component of the code.
