Displaced dome fx right talus, subs for fx w nonunion

This code signifies a specific type of fracture involving the dome of the right talus bone, where the bone fragments are no longer in their normal anatomical alignment. The "nonunion" aspect indicates that the fracture has failed to heal completely after a typical healing period, despite previous treatment.

This code is appropriate for follow-up encounters when a patient is being treated for a previously diagnosed displaced dome fracture of the right talus that has not healed properly. This includes situations where surgical intervention for nonunion is being planned or performed, or during ongoing conservative management for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "right talus" and "displaced dome fracture."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code if the fracture has healed or if it's a different type of talus fracture or a different foot.
