  2. Z codes are used to identify factors influencing health status and contact with health services and may be used as either primary or secondary codes. They are not procedure codes, so they must always have a corresponding procedure code listed to describe any procedure performed.
  3. Z codes are used to identify factors influencing health status and contact with health services and may only be used as secondary codes. They may also be used as procedure codes, so they may be used independently.
