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

This code describes a situation where a patient has a fracture of the posterior process of the talus, which is a bone in the ankle, and the broken pieces of bone are not aligned correctly (displaced). This specific code is used when the patient is receiving follow-up care for this fracture, and the bone has healed in an unsatisfactory position, known as a malunion.

Use this code for a patient presenting for ongoing management of a previously diagnosed displaced posterior talar process fracture that has healed with a malunion. This would include visits for assessing the functional impact of the malunion, planning for corrective surgery, or managing chronic pain related to the improperly healed fracture. It is appropriate for any encounter after the initial treatment phase where the malunion is the focus.

• Ensure documentation clearly states "malunion" and specifies the posterior process of the talus.
• Verify the encounter is for subsequent care, not the initial treatment or routine follow-up without a documented malunion.
• Always code the laterality (left or right) if specified in the medical record; "unspecified" should only be used when laterality is truly unknown.
