Z00 — Encounter for general examination without complaint, suspected or reported diagnosis
Is Z00 billable?
No — Z00 is a non-billable header code.
Z00 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 13 billable codes beneath Z00.
