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

This code describes a situation where a small piece of bone has pulled away from the right talus (an ankle bone) but remains in its normal anatomical position. Importantly, this specific code is used when the fracture has failed to heal properly, and the patient is receiving ongoing care for this nonunion.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced avulsion fracture of the right talus is being treated for a confirmed nonunion. This includes visits for continued conservative management, evaluation for surgical intervention, or post-operative care related to the nonunion.

• Ensure documentation clearly states "nonunion" for the right talus avulsion fracture.
• Verify the fracture is explicitly described as "nondisplaced" and an "avulsion" or "chip" fracture.
• Confirm this is a subsequent encounter, not the initial treatment for the acute fracture.
