Oth fx upr & low end r fibula, subs for clos fx w delay heal

This code signifies a fracture affecting either the top or bottom portion of the right fibula, excluding the shaft, that is currently in a healing phase but is not progressing as expected. The fracture was initially closed, meaning the skin remained intact, and the patient is now receiving follow-up care for this specific injury.

Apply this code when a patient presents for ongoing management of a right fibula fracture (proximal or distal end) that is not healing at the anticipated rate. This would include situations where imaging shows persistent fracture lines or callus formation is delayed, and the initial injury was a closed fracture. It is used for subsequent encounters, not the initial treatment.

• Ensure documentation clearly specifies "delayed healing" for a closed fracture of the upper or lower end of the right fibula.
• Verify this is a subsequent encounter, not the initial treatment or a sequela.
• Distinguish from nonunion or malunion, which have separate codes.
