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

Non-billable headerICD-10-CM

Z03.82 is a non-billable header ICD-10-CM code for encounter for observation for suspected foreign body ruled out. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • retained foreign body (Z18.-)
  • retained foreign body in eyelid (H02.81)
  • residual foreign body in soft tissue (M79.5)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • confirmed foreign body ingestion or aspiration including:
  • foreign body in alimentary tract (T18)
  • foreign body in ear (T16)
  • foreign body on external eye (T15)
  • foreign body in respiratory tract (T17)
