Displaced intartic fx unsp calcaneus, subs for fx w nonunion

This code signifies a fracture within the joint space of the heel bone (calcaneus) that has shifted out of alignment and has failed to heal properly. It specifically applies to situations where the patient is receiving ongoing treatment for this non-healing fracture.

Use this code when a patient presents for follow-up care, cast changes, surgical planning for revision, or other treatment related to a previously diagnosed intraarticular calcaneal fracture that has not united. This code is appropriate when documentation clearly indicates the fracture is displaced and has developed a nonunion.

• Ensure documentation explicitly states "nonunion" or "failed to heal" for the calcaneal fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is intraarticular and displaced, even if the specific calcaneal bone is not identified.
