Z01 — Encounter for other special examination without complaint, suspected or reported diagnosis
Is Z01 billable?
No — Z01 is a non-billable header code. Z01 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 23 billable codes beneath Z01.

Excludes2 — not included here
The conditions below are not part of Z01, but a patient may have both at the same time. When documentation supports it, Z01 and the excluded code may both be reported.
