Unsp fracture of right talus, subs for fx w nonunion

This code signifies an unconfirmed type of fracture affecting the talus bone in the right foot, where the bone has failed to heal properly after an initial injury. The patient is presenting for ongoing treatment or management of this persistent nonunion.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed, but unspecified, right talus fracture is being treated for a nonunion. This includes visits for casting changes, surgical planning for nonunion repair, or monitoring the progress of non-operative management for a non-healing fracture.

• Ensure documentation clearly states "nonunion" and specifies the right talus.
• Verify that the fracture type (e.g., displaced, nondisplaced) was not specified in the initial diagnosis.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
