Oth physl fx lower end unsp fibula, subs for fx w routn heal

This code signifies a fracture affecting the growth plate (physis) at the lower end of the fibula, where the specific type of physeal fracture is not otherwise specified. The patient is in a subsequent phase of care, and the fracture is healing as expected without complications.

Apply this code when a patient presents for follow-up care of a previously diagnosed unspecified physeal fracture of the distal fibula, and the physician's documentation indicates routine healing. This would include cast changes, physical therapy evaluations, or routine radiographic checks during the healing process.

• Ensure documentation explicitly states "subsequent encounter" and "routine healing."
• Verify the fracture location is the lower end of the fibula and involves the physis.
• Do not use for initial encounters or encounters with delayed/nonunion healing.
