Z18 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of retained foreign body fragments. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • embedded fragment (status)
  • embedded splinter (status)
  • retained foreign body status

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note.

  • artificial joint prosthesis status Z96.6
  • foreign body accidentally left during a procedure T81.5
  • foreign body entering through orifice T15 T19
  • in situ cardiac device Z95
  • organ or tissue replaced by means other than transplant Z96 Z97
  • organ or tissue replaced by transplant Z94
  • personal history of retained foreign body fully removed Z87.821

Patient Education


Foreign Bodies

If you've ever gotten a splinter or had sand in your eye, you've had experience with a foreign body. A foreign body is something that is stuck inside you but isn't supposed to be there. You may inhale or swallow a foreign body, or you may get one from an injury to almost any part of your body. Foreign bodies are more common in small children, who sometimes stick things in their mouths, ears, and noses.

Some foreign bodies, like a small splinter, do not cause serious harm. Inhaled or swallowed foreign bodies may cause choking or bowel obstruction and may require medical care.
