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

This code signifies a fracture affecting the growth plate (physis) at the top portion of the right fibula, which is not further specified as Salter-Harris type I, II, III, or IV. The patient is in a phase of treatment where the fracture is not healing at the expected rate, indicating delayed union.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed, unspecified physeal fracture of the upper right fibula is experiencing delayed healing. It should be used when the physician documents that the fracture is not progressing towards union as anticipated, requiring ongoing management.

• Ensure documentation clearly specifies "delayed healing" for the fracture.
• Verify the fracture location is the "upper end of the right fibula" and involves the physis.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
