Nondisp oblique fx shaft of unsp tibia, 7thN

This code describes a situation where a patient has a non-displaced oblique fracture in the shaft of an unspecified tibia, and the fracture has not healed properly (nonunion). This specific encounter is for an open fracture classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and potential contamination.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed non-displaced oblique tibial shaft fracture that has failed to unite. This applies specifically when the initial injury was an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC, and the current encounter addresses the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original fracture was an "open fracture" and its Gustilo-Anderson classification (IIIA, IIIB, or IIIC).
• Do not use this code for initial encounters or for fractures that are healing normally.
