Oth fx upr & low end l fibula, 7thM

This code describes a fracture of either the top or bottom portion of the left fibula that has not healed properly (nonunion) and was initially an open fracture of Type I or II. The patient is presenting for follow-up care or treatment related to this unhealed fracture.

Use this code for a patient presenting for ongoing management of a previously sustained open fibula fracture (Type I or II) of the upper or lower end, where the bone has failed to unite. This applies to situations such as follow-up appointments, cast changes, or surgical interventions for the nonunion.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (I or II).
• Verify the fracture location is specifically the upper or lower end of the left fibula.
• This code is for subsequent encounters, not the initial treatment of the fracture.
