Disp fx of greater trochanter of l femr, 7thN

This code signifies a fracture of the greater trochanter on the left femur that has become displaced, meaning the bone fragments are no longer in proper alignment. It specifically indicates that this is a subsequent encounter for an open fracture, classified as Type IIIA, IIIB, or IIIC, and that the fracture has failed to heal properly (nonunion).

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced open fracture of the left greater trochanter that has developed nonunion. This applies when the initial open fracture was severe, involving significant soft tissue damage (Type IIIA, IIIB, or IIIC). This code would be appropriate for ongoing management, surgical planning for nonunion, or monitoring of the nonunion.

• Ensure documentation clearly specifies "displaced" and "left" femur.
• Verify the original open fracture was classified as Type IIIA, IIIB, or IIIC.
• Confirm the encounter is for the nonunion of the fracture, not the initial injury or routine healing.
