Z84.8Family history of other specified conditions

Z84.8 is the ICD-10-CM diagnosis code for family history of other specified conditions. It belongs to category Z84 (family history of other conditions), 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 a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Z84, choose Z84.8 (other specified conditions) only when documentation doesn't support a more specific option: diseases of the skin and subcutaneous tissue (Z84.0), disorders of kidney and ureter (Z84.1), other diseases of the genitourinary system (Z84.2), consanguinity (Z84.3) and exposure to diethylstilbestrol (Z84.A).

To report this condition, pick the subcode that matches the documentation: Z84.81 (disease), Z84.82 (syndrome) and Z84.89 (conditions).

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