Unacceptable principal diagnosis
There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.

Questions About Z17.410Overview

Is Z17.410 (Hormone receptor positive) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report hormone receptor positive with human epidermal growth factor receptor 2 positive status on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z17.410 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because hormone receptor positive with human epidermal growth factor receptor 2 positive status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z17.410 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 hormone receptor positive with human epidermal growth factor receptor 2 positive status on inpatient claims.
