Z01: Encounter for other special examination without complaint, suspected or reported diagnosis

Non-billable headerICD-10-CM

Z01 is a non-billable header ICD-10-CM code for encounter for other special examination without complaint, suspected or reported diagnosis. 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.

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.
