Unsp fx shaft of unsp fibula, subs for clos fx w malunion

This code signifies a fracture of the main part (shaft) of the lower leg bone (fibula) where the specific location on the fibula is not documented. It indicates that the patient is in a later stage of healing for a previously treated closed fracture, but the bone has healed in an abnormal position (malunion).

This code is appropriate for follow-up encounters where a patient is being managed for a fibular shaft fracture that has healed incorrectly, and the initial fracture was closed. It should be used when the precise location of the fibular shaft fracture (e.g., proximal, distal, midshaft) is not specified in the medical record.

• Ensure documentation clearly states "malunion" and "subsequent encounter" for a closed fracture.
• Avoid using this code if the specific location of the fibular shaft fracture is documented; instead, use a more specific code from the S82.4- series.
• This code is for the fibula only; do not use if the tibia is also involved.
