Displ transverse fx shaft of l fibula, 7thM

This code indicates a break in the middle section of the left fibula bone, where the bone fragments are no longer aligned. It specifically describes a situation where the initial fracture was an open fracture (meaning the skin was broken), and the bone has failed to heal properly in a later stage of treatment.

Apply this code when documenting ongoing care for a patient whose left fibula shaft fracture, initially an open fracture of Type I or II, has not united. This would be used during follow-up visits, rehabilitation, or further surgical interventions addressing the nonunion.

• Ensure documentation clearly specifies "left" fibula and "transverse" fracture type.
• Confirm the original injury was an "open fracture type I or II" and that "nonunion" is explicitly stated or clearly implied.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute injury.
