Displ avuls fx tuberosity of unsp calcaneus, 7thK

This code signifies a fracture where a piece of bone has been pulled away from the main bone by a tendon or ligament, specifically located at the tuberosity of the calcaneus (heel bone). The fracture is displaced, meaning the bone fragments are not properly aligned, and it has failed to heal after an initial treatment, indicating a nonunion.

This code is appropriate for follow-up encounters when a patient is being treated for a previously diagnosed avulsion fracture of the calcaneal tuberosity that has not healed. This includes situations where surgical intervention or other treatments are being pursued to address the nonunion.

• Ensure documentation clearly states "nonunion" for this specific fracture site.
• Verify the fracture is explicitly described as "displaced" and an "avulsion" type.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
