What This Code Means
Z84.2 is the ICD-10-CM diagnosis code for family history of other diseases of the genitourinary system. A family member has had diseases or conditions affecting the urinary or reproductive system. Z84.2 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).
Z84.2 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code covers family history of conditions like bladder disease, prostate disease, and reproductive system disorders.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z84.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
