Displ transverse fx shaft of l rad, 7thN

This code describes a situation where a patient has a non-healing, displaced fracture of the shaft of their left radius, specifically a transverse break. This particular nonunion is occurring in an open fracture that was initially classified as Type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed open transverse fracture of the left radial shaft that has failed to heal (nonunion). This applies when the initial open fracture was severe (Type IIIA, IIIB, or IIIC). This code would be appropriate for ongoing management, such as repeat imaging, surgical planning for nonunion repair, or continued wound care.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented, as this code is specific to these severe open fracture classifications.
• Do not use this code for initial encounters or for malunion; nonunion must be explicitly stated.
