Radiation Therapy
Radiation therapy is a cancer treatment. It uses high doses of radiation to kill cancer cells and stop them from spreading. It may also be used for easing cancer symptoms. Radiation therapy may damage healthy cells. They can usually repair themselves more easily than cancer cells.

Questions About Z92.3Overview
Is Z92.3 (Personal history of medical treatment) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report personal history of irradiation on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z92.3 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because personal history of irradiation describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z92.3 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 irradiation on inpatient claims.
What is the ICD-9 equivalent of Z92.3?
Under the General Equivalence Mappings, personal history of irradiation converts to ICD-9-CM V15.3 (hx of irradiation). The mapping is a direct match.
