Nondisp fx of neck of unsp talus, subs for fx w nonunion

This code signifies a fracture of the talus bone's neck that was initially nondisplaced but has failed to heal properly. The "subsequent encounter" indicates that the patient is receiving ongoing care for this unhealed fracture, and "nonunion" confirms that the bone fragments have not united after a reasonable healing period. The "unspecified talus" denotes that the laterality (left or right) of the talus is not documented.

Use this code for follow-up visits where a patient is being treated for a previously diagnosed nondisplaced talar neck fracture that has progressed to nonunion. This would include scenarios such as evaluation for surgical intervention to promote healing, ongoing conservative management for nonunion, or assessment of complications related to the nonunion.

• Ensure documentation clearly states "nonunion" and that the fracture was initially nondisplaced.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• If laterality (left or right talus) is documented, a more specific code should be selected.
