Displ spiral fx shaft of ulna, l arm, 7thM

This code signifies a left ulna shaft fracture, specifically a spiral type, where the bone fragments are no longer in their normal alignment. It indicates that the fracture was initially an open fracture (Type I or II) and is now being treated for a nonunion, meaning the bone is failing to heal properly.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed and treated open spiral fracture of the left ulnar shaft (Type I or II) is presenting with complications of nonunion. This would include scenarios such as ongoing pain, instability, or imaging evidence of failed bone healing.

• Ensure documentation clearly specifies "left arm" and "spiral fracture" of the ulna shaft.
• Verify the original injury was an "open fracture type I or II" and that the current encounter addresses "nonunion."
• This code is for subsequent encounters; an initial encounter for the fracture would use an initial encounter code.
