Official Coding Guidelines

Aftercare: use of status Z codes with aftercare Z codes; exceptions

Status Z codes may be used with aftercare Z codes to indicate the nature of the aftercare. For example, code Z95.1, Presence of aortocoronary bypass graft, may be used with code Z48.812, Encounter for surgical aftercare following surgery on the circulatory system, to indicate the surgery for which the aftercare is being performed. A status code should not be used when the aftercare code indicates the type of status, such as using Z43.0, Encounter for attention to tracheostomy, with Z93.0, Tracheostomy status.

Used with any code in range A00.0-T88.9, Z00-Z99
