Disp fx of body of unsp calcaneus, subs for fx w nonunion

This code describes a situation where a patient has a fracture in the main part of the heel bone (calcaneus) that is no longer in its proper anatomical alignment. Crucially, this code is used when the fracture has failed to heal after an initial treatment, indicating a nonunion, and the patient is presenting for further care related to this ongoing issue.

Use this code for follow-up encounters where a previously diagnosed displaced calcaneal body fracture (of an unspecified side) has not healed and is now considered a nonunion. This would apply when the patient is undergoing continued treatment, evaluation, or management for this unhealed fracture.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify that the encounter is for subsequent care of the fracture, not the initial treatment.
• Confirm the fracture location is the body of the calcaneus and laterality is unspecified if not documented.
