Displ oth fx tuberosity of unsp calcaneus, 7thK

This code signifies a fracture of the calcaneal tuberosity that is not in its normal anatomical position and has failed to heal properly. The injury involves the heel bone, specifically the prominent bony projection at the back, and is in a stage where the bone fragments have not united after a previous treatment attempt.

Apply this code when documenting a patient encounter for ongoing management of a displaced tuberosity fracture of the calcaneus that has been diagnosed with nonunion. This is appropriate for follow-up visits, surgical planning for nonunion repair, or conservative management of the unhealed fracture.

• Ensure documentation clearly states "nonunion" and "displaced" for the calcaneal tuberosity fracture.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Verify the fracture location is specifically the tuberosity of the calcaneus.
