Displ seg fx shaft of rad, r arm, 7thN

This code signifies a right arm radius shaft fracture that is both displaced and segmental, meaning the bone is broken into at least three pieces. It specifically indicates that the fracture is an open fracture of severe type (IIIA, IIIB, or IIIC) and has failed to heal properly, resulting in a nonunion. This is a subsequent encounter, meaning the patient is returning for ongoing treatment of this unhealed fracture.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed, severely open, displaced segmental fracture of the right radial shaft that has not healed. This would apply when the physician is assessing the nonunion, planning further interventions, or managing complications related to the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" for the fracture.
• Verify the fracture is explicitly described as "segmental" and "displaced" in the right radius shaft.
• Confirm the initial injury was an "open fracture type IIIA, IIIB, or IIIC" and this is a subsequent encounter.
