Displ avuls fx (chip fracture) of r talus, 7thK

This code signifies a fracture where a small piece of bone has been pulled away from the main bone of the right talus, specifically due to an avulsion injury. The fracture is displaced, meaning the bone fragments are not in their normal alignment. This particular code is used when the patient is receiving ongoing treatment for this fracture, and the bone is failing to heal properly (nonunion).

Apply this code for follow-up encounters when a patient with a previously diagnosed displaced avulsion fracture of the right talus is being treated for a nonunion. This includes scenarios where surgical intervention for nonunion is being planned or performed, or conservative management for the nonunion is ongoing. It indicates that the fracture has not healed within the expected timeframe and requires further medical attention.

• Ensure documentation clearly states "nonunion" for the right talus avulsion fracture.
• Verify the fracture is specifically an avulsion (chip) type and is displaced.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
