Displ seg fx shaft of unsp tibia, 7thR

This code signifies a segmental fracture of the tibial shaft that is displaced and has developed malunion. It specifically applies to open fractures initially classified as Type IIIA, IIIB, or IIIC, and is used during follow-up care after the initial treatment.

Use this code when documenting a subsequent encounter for a patient with a previously treated open segmental tibial shaft fracture (Gustilo-Anderson Type IIIA, IIIB, or IIIC) that has healed in an unsatisfactory position, resulting in malunion. This would be appropriate for patients presenting for evaluation of persistent pain, deformity, or functional limitations due to the malunion.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" for an open fracture.
• Verify the original fracture was a segmental fracture of the tibial shaft and classified as Gustilo-Anderson Type IIIA, IIIB, or IIIC.
• Do not use this code for initial fracture treatment or for nonunion.
