Displ oblique fx shaft of unsp tibia, 7thN

This code signifies a tibia shaft fracture that is both displaced and has an oblique pattern, specifically in an unspecified tibia. The fracture is an open type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. This particular code is used during a subsequent encounter when the fracture has failed to heal, resulting in nonunion.

Apply this code when documentation confirms a patient is presenting for follow-up care of a previously treated open oblique tibia shaft fracture (types IIIA, IIIB, or IIIC) that has not achieved bony union. This typically occurs after initial treatment, such as surgical fixation, has been performed, and the fracture site remains unhealed. It is appropriate for ongoing management of the nonunion.

• Ensure the documentation clearly specifies "nonunion" for this subsequent encounter.
• Verify the fracture type is explicitly stated as IIIA, IIIB, or IIIC for open fractures.
• Do not use for initial encounters or for fractures that are healing normally.
