Disp fx of r tibial tuberosity, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture of the right tibial tuberosity that is not in its normal anatomical alignment, and the fracture has failed to heal after an initial treatment. This specific code is used when the patient is seen for follow-up care of this unhealed fracture, and the skin over the fracture site remains intact (closed fracture).

This code is appropriate for subsequent encounters when a patient with a previously diagnosed and treated displaced right tibial tuberosity fracture presents for ongoing management of a nonunion. This includes office visits, follow-up imaging, or other services related to addressing the persistent nonunion of the closed fracture.

• Ensure documentation clearly specifies "nonunion" for the subsequent encounter.
• Verify the fracture is of the "right tibial tuberosity" and is "displaced."
• Confirm the fracture is "closed" (skin intact) to differentiate from open fractures.
