Displ commnt fx shaft of l femr, 7thN

This code signifies a complex, displaced comminuted fracture involving the shaft of the left femur, meaning the bone is broken into multiple fragments and the pieces are not in their normal alignment. It specifically indicates that this is an open fracture (where the bone has broken through the skin) of a severe type (IIIA, IIIB, or IIIC), and the fracture has failed to heal properly in a subsequent encounter.

Use this code for follow-up encounters when a patient is being treated for a previously diagnosed severe open comminuted fracture of the left femoral shaft that has developed nonunion. This applies to ongoing management, assessment of healing progress, or planning for further intervention due to the nonunion. It should be assigned when the nonunion is explicitly documented.

• Ensure documentation clearly specifies "nonunion" for this subsequent encounter.
• Verify the fracture site is the shaft of the left femur and the open fracture type is IIIA, IIIB, or IIIC.
• Do not use for initial encounters or for fractures that are healing normally.
