Disp fx of ant pro of unsp calcaneus, subs for fx w malunion

This code signifies a fracture of the anterior process of the calcaneus (heel bone) that has healed incorrectly, resulting in a malunion. The fracture was displaced, meaning the bone fragments were not in proper alignment at the time of injury. This specific code is used for follow-up care related to this malunited fracture.

Use this code when a patient presents for ongoing treatment, evaluation, or management of a previously sustained, displaced anterior calcaneal process fracture that has healed in an unsatisfactory position. This includes scenarios where the malunion is causing symptoms, requiring further intervention, or being monitored. It is appropriate for any encounter after the initial treatment of the acute fracture.

• Ensure documentation clearly states "malunion" and specifies the "anterior process" of the calcaneus.
• Verify the encounter is for follow-up care, not the initial treatment of the acute fracture.
• Laterality is unspecified in this code; if known, a more specific code should be sought.
