Unsp physeal fx lower end of l tibia, subs for fx w malunion

This code signifies a fracture of the growth plate at the lower end of the left shin bone, where the bone has healed improperly (malunion). This specific code is used when the patient is receiving follow-up care for this malunited fracture.

Apply this code when a patient presents for ongoing management, evaluation, or treatment of a previously diagnosed and treated physeal fracture of the distal left tibia that has resulted in malunion. This includes scenarios such as monitoring for growth disturbances, planning for corrective surgery, or managing residual pain or functional limitations due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the "left tibia" and "lower end" (distal).
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Confirm the fracture involves the "physeal" (growth plate) region.
