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

This code signifies a follow-up encounter for a patient with a non-displaced avulsion fracture, also known as a chip fracture, of an unspecified talus bone. The key characteristic for this specific code is that the fracture has not healed properly and is experiencing nonunion.

Utilize this code when a patient presents for ongoing management of a talus chip fracture that has failed to unite. This would typically involve clinic visits, imaging studies, or discussions about further intervention for the nonunion. It is appropriate for subsequent encounters after the initial treatment.

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