Displ commnt fx shaft of r fibula, 7thN

This code describes a complex fracture of the shaft of the right fibula that has broken into multiple pieces and is no longer in its normal anatomical alignment. The fracture is an open type IIIA, IIIB, or IIIC, meaning there is a significant wound communicating with the fracture site, and the bone has failed to heal properly after an initial treatment.

Use this code for follow-up encounters when a patient presents with a previously treated, displaced, comminuted open fracture of the right fibular shaft that has developed nonunion. This applies to situations where the patient is receiving ongoing care for the nonunion, such as further surgical intervention, cast changes, or monitoring.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the fibular shaft and not another part of the fibula.
• Confirm this is a subsequent encounter for the nonunion, not the initial treatment of the fracture.
