Oth physeal fx lower end of r tibia, subs for fx w malunion

This code describes a fracture involving the growth plate (physis) at the lower end of the right shin bone that is currently healing incorrectly (malunion). This specific code is used when the patient is receiving follow-up care for this previously diagnosed and treated injury.

Apply this code when a patient presents for ongoing management of a malunited physeal fracture of the distal right tibia. This includes scenarios such as follow-up appointments, physical therapy, or surgical planning to correct the malunion after initial treatment. It indicates that the fracture is not yet fully healed and is consolidating in an anatomically incorrect position.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for ongoing care.
• Verify the fracture location is the lower end of the right tibia and involves the physis.
• Do not use this code for initial treatment or for nonunion; a different seventh character would be required.
