Unspecified physeal fracture of unspecified calcaneus, 7thK

This code signifies a fracture occurring through the growth plate (physis) of the heel bone (calcaneus) in an unspecified location, where the fracture has failed to heal properly after an initial treatment attempt. This indicates a complication in the healing process, requiring further medical intervention.

Apply this code when documenting a patient's follow-up visit for a previously diagnosed calcaneal physeal fracture that has not united, meaning the bone fragments have not fused together. This is appropriate for subsequent encounters where nonunion is the primary focus of treatment or evaluation.

• Ensure documentation clearly states "nonunion" of the physeal fracture and specifies the calcaneus.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Look for associated external cause codes if the mechanism of injury is known and relevant.
