Z03.82Encounter for observation for suspected foreign body ruled out

Z03.82 is the ICD-10-CM diagnosis code for encounter for observation for suspected foreign body ruled out. It belongs to category Z03 (encounter for medical observation for suspected diseases and conditions ruled out), block Z00-Z13 (persons encountering health services for examinations) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Z03.8 (encounter for observation for other suspected diseases and conditions ruled out), Z03.82 is specifically for encounter for observation for suspected foreign body ruled out. Related codes cover suspected exposure to biological agents ruled out (Z03.81), suspected conditions related to home physiologic monitoring device ruled out (Z03.83) and other suspected diseases and conditions ruled out (Z03.89).

To report this condition, pick the subcode that matches the documentation: Z03.821 (out), Z03.822 (out) and Z03.823 (out).

Don't report Z03.82 together with the conditions in its Excludes1 note: retained foreign body (Z18.-), retained foreign body in eyelid (H02.81) and residual foreign body in soft tissue (M79.5).

The conditions in its Excludes2 note aren't part of Z03.82, but may be coded alongside it if the patient has both: foreign body in alimentary tract (T18), foreign body in ear (T16), foreign body on external eye (T15) and foreign body in respiratory tract (T17).

It was added in FY2021, effective October 1, 2020.
