Z83.0Family history of human immunodeficiency virus [HIV] disease

Z83.0 is the ICD-10-CM diagnosis code for family history of human immunodeficiency virus [HIV] disease. It belongs to category Z83 (family history of other specific disorders), 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 Z83 (family history of other specific disorders), Z83.0 is specifically for family history of human immunodeficiency virus [HIV] disease. Related codes cover other infectious and parasitic diseases (Z83.1), diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z83.2), diabetes mellitus (Z83.3), other endocrine, nutritional and metabolic diseases (Z83.4), eye and ear disorders (Z83.5), other diseases of the respiratory system (Z83.6) and diseases of the digestive system (Z83.7).

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 V19.8 (family history of other condition).
