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

This code signifies a fracture of the talar neck in the left foot that has not shifted from its anatomical position, and the patient is presenting for follow-up care where the fracture has failed to heal properly. Nonunion indicates that the bone ends have not united after a sufficient healing period, potentially requiring further intervention.

Apply this code when a patient with a previously diagnosed nondisplaced left talar neck fracture returns for an encounter where imaging or clinical assessment confirms that the fracture has not healed. This is appropriate for ongoing management of the nonunion, such as discussions about bone grafting, revision surgery, or continued conservative management.

• Ensure documentation clearly states "nonunion" and specifies the "left" talus.
• Verify that the fracture was initially "nondisplaced" to align with this specific code.
• This code is for a "subsequent encounter," meaning it's not for the initial treatment of the fracture.
