Z00: Encounter for general examination without complaint, suspected or reported diagnosis
Non-billable headerICD-10-CM
Z00 is a non-billable header ICD-10-CM code for encounter for general 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.
- encounter for examination for administrative purposes (Z02.-)
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.
Other codes that can never be billed with Z00
Their own Excludes1 notes name this code, so the conflict is not listed above.
Risk adjustment
No CMS-HCC V28 category: this code does not change a RAF score.
