Oth physl fx upper end of l fibula, subs for fx w delay heal

This code signifies a fracture affecting the growth plate (physis) at the top portion 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 is experiencing delayed healing, meaning it is taking longer than expected to unite.

Apply this code for follow-up encounters where a patient with a previously diagnosed, unspecified physeal fracture of the proximal left fibula is being treated for delayed union. This would include scenarios where imaging shows incomplete healing beyond the typical timeframe, or clinical signs of non-consolidation are present.

• Ensure documentation clearly states "delayed healing" for the fracture.
• Verify the fracture location is the "upper end of the left fibula" and involves the physis.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
