Unsp physl fx upper end of l fibula, subs for fx w malunion

This code describes a situation where a child or adolescent has sustained an unspecified fracture of the growth plate at the top of their left fibula. The fracture is now in a healing phase, but the bone fragments have united in an abnormal position, leading to a malunion. This can result in functional impairment or deformity.

Use this code when documenting follow-up care for a pediatric patient with a previously diagnosed, unspecified physeal fracture of the proximal left fibula that has healed incorrectly. This applies to encounters where the malunion is being assessed, monitored, or treated, and the initial fracture treatment has concluded.

• Ensure "subsequent encounter" is appropriate; do not use for initial treatment or active healing without malunion.
• Verify laterality (left) and bone (fibula) are correctly documented.
• Confirm the fracture is specifically of the physis (growth plate) and not another part of the fibula.
