Z80-Z99: Persons with potential health hazards related to family and personal history and certain conditions influencing health status

Z97: Presence of other devices

Z97, entitled "Presence of other devices", falls under a group of codes denoting health conditions primarily associated with the use of various artificial devices, implants, and grafts. These are used for a wide range of reasons from cardiac operations to organ transplants. Typically, these codes are used when the introduced device is functioning as expected yet continue to impact a patient's overall health status. The impact may manifest in various ways – foreign body reactions may occur, risk of infections may increase, or mechanical disruptions may arise depending on the device in question. How these conditions present may also differ dramatically; some patients may experience physical discomfort while others may have radiographic or laboratory abnormalities with no noticeable symptoms. This group of conditions is inherently diverse due to the wide range of device types and individual medical histories.
