Z92.3Personal history of irradiation

Z92.3 is the ICD-10-CM diagnosis code for personal history of irradiation. It belongs to category Z92 (personal history of medical treatment), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z92 (personal history of medical treatment), Z92.3 is specifically for personal history of irradiation. Related codes cover contraception (Z92.0), drug therapy (Z92.2) and other medical treatment (Z92.8).

Don't report Z92.3 together with the conditions in its Excludes1 note: exposure to radiation in the physical environment (Z77.12) and occupational exposure to radiation (Z57.1).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as V15.3 (personal history of irradiation, presenting hazards to health).
