Nondisp seg fx shaft of rad, l arm, 7thN

This code describes a left radius fracture that involves a segment of the bone shaft, is not displaced, and was initially an open fracture (Type IIIA, IIIB, or IIIC). The current encounter is for ongoing management of this fracture, specifically addressing a nonunion, meaning the bone has failed to heal properly.

Use this code for follow-up encounters where a patient with a previously diagnosed open segmental shaft fracture of the left radius is being treated for a confirmed nonunion. This applies when the fracture was initially classified as an open fracture of severe type (IIIA, IIIB, or IIIC) and the nonunion is the primary focus of the current visit.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the left radius shaft and is segmental and nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
