Cancer

Cancer is not just one disease but many diseases. Cancer begins in your cells, which are the building blocks of your body. Usually, your body forms new cells as needed, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should.

Questions About Z86.002Overview

Is Z86.002 (Personal history of in-situ neoplasm) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report personal history of in-situ neoplasm of other and unspecified genital organs on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z86.002 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of in-situ neoplasm of other and unspecified genital organs describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z86.002 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 personal history of in-situ neoplasm of other and unspecified genital organs on inpatient claims.
