Disp fx of nk of r rad, 7thN

This code signifies a displaced fracture of the neck of the right radius that was initially an open fracture (Type IIIA, IIIB, or IIIC) and is now experiencing a nonunion. Nonunion indicates that the bone fragments have failed to heal together after a significant period.

This code is appropriate for subsequent encounters when a patient with a previously treated open fracture of the right radial neck presents with evidence of nonunion. This typically occurs during follow-up appointments where imaging confirms the lack of bone healing.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (right radius) is explicitly stated in the medical record.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
