Displ commnt fx shaft of unsp tibia, 7thJ

This code signifies a complex injury involving a displaced fracture of the main part of the tibia, where the bone has broken into multiple fragments. It specifically indicates that the fracture is an open type IIIA, IIIB, or IIIC, meaning there's a significant wound communicating with the fracture site, and the patient is in a later stage of healing where the bone union is progressing slower than expected.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed open comminuted tibial shaft fracture (types IIIA, IIIB, or IIIC) is experiencing delayed healing. It should be used when the patient is receiving ongoing treatment for this specific fracture and the healing process is not progressing at the anticipated rate.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the original injury was an open comminuted fracture of the tibial shaft, type IIIA, IIIB, or IIIC.
• Do not use for initial encounters or for nonunion/malunion, which have separate codes.
