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

This code signifies a follow-up encounter for a growth plate fracture located at the distal end of the right shin bone, where the fracture has healed improperly, resulting in a deformity. This malunion indicates that the bone fragments have joined in an anatomically incorrect position, potentially affecting limb function or growth.

Use this code when a patient presents for ongoing management or evaluation of a previously sustained, unspecified physeal fracture of the lower right tibia that has healed with malunion. This applies to situations such as assessing the functional impact of the malunion, planning corrective surgery, or monitoring for growth disturbances.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the laterality (right) and the specific bone (tibia) and location (lower end/physeal).
• Do not use for initial encounters or for nonunion; separate codes exist for those scenarios.
