Nondisp dome fracture of left talus, subs for fx w nonunion

This code signifies a fracture of the dome of the left talus that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing care for this specific fracture, and it has failed to heal properly after an expected period.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a previously diagnosed nondisplaced dome fracture of the left talus that has been determined to have nonunion. This would include visits for assessing the nonunion, discussing treatment options for nonunion (e.g., surgery, bone stimulation), or managing complications related to the unhealed fracture.

• Ensure documentation clearly states "nonunion" for the left talus fracture.
• Verify the fracture is specifically of the "dome" and is "nondisplaced."
• This code is for subsequent encounters; an initial encounter for the same fracture would use a different seventh character.
