Oth fx upr & low end unsp fibula, 7thM

This code describes a fracture of the fibula, which is the smaller bone in the lower leg, that has not healed properly (nonunion) and was initially an open fracture (meaning the skin was broken). This specific code is used when the exact location of the fracture on the fibula (upper or lower end) is not documented, and the patient is receiving follow-up care for this unhealed open fracture.

Use this code for a patient presenting for ongoing treatment of a previously sustained open fibula fracture (Type I or II) that has failed to unite. This includes situations where the patient is undergoing procedures like bone grafting, internal fixation revision, or other interventions aimed at promoting healing of the nonunion. It is appropriate when the medical record does not specify whether the fracture was of the proximal or distal fibula.

• Ensure documentation clearly states "nonunion" and "open fracture type I or II" for the fibula.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Only use this code when the specific location of the fibula fracture (upper or lower end) is not documented.
