Oth physeal fx lower end of l fibula, subs for fx w malunion

This code indicates a fracture of the growth plate (physis) at the lower end of the left fibula, which is not further specified as Salter-Harris type I, II, III, or IV. The patient is in a subsequent phase of care, and the fracture has healed incorrectly, resulting in a malunion.

This code is appropriate for follow-up encounters where a previously diagnosed, unspecified physeal fracture of the distal left fibula is being managed, and imaging or clinical assessment confirms that the bone has healed in an abnormal alignment. It would be used when addressing complications or ongoing treatment related to this malunion.

• Ensure documentation clearly specifies "malunion" for a subsequent encounter.
• Verify the laterality (left fibula) and the specific location (lower end) are documented.
• Do not use this code for initial encounters or for fractures healing normally or with nonunion.
