Nondisp avuls fx (chip fracture) of l talus, 7thP

This code describes a specific type of ankle fracture where a small piece of bone has been pulled away from the main bone (avulsion or chip fracture) of the left talus. The fracture fragments are still in their normal anatomical alignment (nondisplaced), but the healing process has resulted in an imperfect union of the bone fragments (malunion).

Use this code for follow-up encounters when a patient is being treated for a previously diagnosed nondisplaced avulsion fracture of the left talus that has healed improperly. This indicates the fracture has united, but in a position that is not anatomically correct, potentially causing ongoing symptoms or functional limitations.

• Ensure documentation clearly states "malunion" and specifies the left talus.
• Verify the fracture was initially nondisplaced and an avulsion/chip type.
• This code is for subsequent encounters, not the initial treatment of the fracture.
