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

This code describes a fracture of the right tibial tuberosity that has healed in an abnormal position (malunion) and is being treated in a follow-up encounter. The fracture was initially closed, meaning the skin was not broken. The "displaced" aspect indicates the bone fragments were not in their normal alignment at the time of injury.

Use this code for patients presenting for ongoing management or evaluation of a previously treated right tibial tuberosity fracture that has resulted in malunion. This applies to situations such as physical therapy, follow-up imaging to assess the malunion, or discussions regarding potential corrective surgery. It is appropriate when the initial treatment for the fracture is complete, but the malunion requires further attention.

• Ensure documentation clearly states "malunion" and specifies the right tibial tuberosity.
• Verify that the encounter is for follow-up care of the closed fracture, not initial treatment or active healing.
• Do not use this code if the fracture is still in the acute healing phase or if it is a nonunion.
