Displ commnt fx shaft of rad, l arm, 7thM

This code describes a severe, multi-fragmented break in the main part of the left radius bone, where the bone pieces are no longer in their normal alignment. This specific instance refers to an open fracture (meaning the skin was broken) that is not healing properly, and the patient is receiving follow-up care for this complication.

Use this code for a patient presenting for ongoing treatment of a previously diagnosed open comminuted fracture of the left radial shaft (Type I or II) that has failed to unite. This would apply during subsequent visits for procedures like bone grafting, revision surgery, or extended immobilization due to nonunion.

• Ensure documentation clearly specifies "left arm" and "nonunion" for accurate code assignment.
• Verify the open fracture type (I or II) is documented, as this code is specific to those types.
• This code is for subsequent encounters; an initial encounter would use a different code.
