Oth fracture of right talus, subs for fx w nonunion

This code signifies a fracture of the right talus, excluding specific types like neck or body fractures, that has failed to heal properly. The "nonunion" indicates that the bone ends have not united after a sufficient healing period, and the "subsequent encounter" specifies that this is not the initial treatment for the fracture.

Apply this code when a patient presents for follow-up care of a previously diagnosed right talus fracture that has been determined to have nonunion. This would include scenarios where surgical intervention for the nonunion is being planned or performed, or during ongoing conservative management for a confirmed nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right talus.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code for malunion; a different code exists for that condition.
