Z18 vs Z95
Z18 (Retained foreign body fragments) compared with Z95 (Presence of cardiac and vascular implants and grafts), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Z18 carries an Excludes1 note covering Z95: “in situ cardiac device (Z95.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
