Nondisp fx of post pro of unsp talus, subs for fx w nonunion

This code describes a fracture of the back part of the talus bone in the ankle that has not shifted out of alignment. It specifically indicates that the fracture is not healing properly, resulting in a nonunion, and the patient is being seen for follow-up care related to this ongoing issue. The exact talus (left or right) is not specified.

Apply this code when documentation confirms a non-displaced fracture of the posterior talar process that has failed to unite, and the patient is presenting for subsequent treatment or evaluation of this nonunion. This would include visits for ongoing management, imaging to assess nonunion status, or preparation for surgical intervention for the nonunion.

• Ensure documentation clearly states "nonunion" and "nondisplaced" for the posterior process.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• If laterality (left or right) is specified, choose a more specific code from the S92.13- series.
