Disp fx of post pro of right talus, subs for fx w nonunion

This code signifies a fracture of the posterior process of the right talus that is no longer in its anatomical alignment. The "subsequent encounter" indicates the patient is receiving active treatment for the fracture after the initial encounter, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed, displaced fracture of the posterior process of the right talus, and imaging or clinical assessment confirms that the fracture has not united. This includes scenarios such as cast changes, physical therapy, or surgical planning for nonunion repair.

• Always confirm laterality (right) and the specific bone involved (talus, posterior process).
• Ensure documentation clearly states "displaced" and "nonunion" for accurate code assignment.
• Verify that this is a subsequent encounter for active treatment, not a sequela or initial encounter.
