Displaced transverse fx unsp acetab, subs for fx w nonunion

This code signifies a fracture of the transverse portion of the acetabulum, where the bone fragments are no longer in their normal alignment. It specifically indicates that the patient is receiving ongoing treatment for this fracture, and a complication of nonunion (failure of the bone to heal) has been identified.

Use this code for a patient presenting for follow-up care, cast changes, or other ongoing management of a previously diagnosed displaced transverse acetabular fracture. The key is the documentation of nonunion as a current complication of the healing process. This code is appropriate when the initial treatment has failed to achieve bone union.

• Ensure documentation clearly specifies "displaced" and "transverse" for the acetabular fracture.
• Verify that "nonunion" is explicitly stated as a current complication in the medical record.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
