Questions About Z15.068Overview

Is Z15.068 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report genetic susceptibility to other malignant neoplasm of digestive system on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z15.068 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because genetic susceptibility to other malignant neoplasm of digestive system describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z15.068 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for genetic susceptibility to other malignant neoplasm of digestive system on inpatient claims.
