Displ intartic fx unsp calcaneus, subs for fx w delay heal

This code signifies a break within the joint surface of the heel bone (calcaneus) that has shifted from its normal alignment. The fracture is not healing as expected, and the patient is receiving ongoing care for this delayed union. The specific side (left or right) of the foot is not documented.

Use this code when a patient presents for follow-up care of a previously diagnosed displaced intraarticular calcaneal fracture, and the physician's documentation indicates delayed healing. This applies to situations where the fracture has not united within the expected timeframe, requiring continued management.

• Ensure documentation explicitly states "delayed healing" for the calcaneal fracture.
• Verify the fracture is intraarticular and displaced; if not, a different code is required.
• Confirm this is a subsequent encounter, not the initial treatment of the fracture.
