Z82.4Family history of ischemic heart disease and other diseases of the circulatory system

Z82.4 is the ICD-10-CM diagnosis code for family history of ischemic heart disease and other diseases of the circulatory system. It belongs to category Z82 (family history of certain disabilities and chronic diseases (leading to disablement)), 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 2 subcodes must be used instead.

Within Z82, choose Z82.4 (ischemic heart disease and other diseases of the circulatory system) only when documentation doesn't support a more specific option: epilepsy and other diseases of the nervous system (Z82.0), blindness and visual loss (Z82.1), deafness and hearing loss (Z82.2), stroke (Z82.3), asthma and other chronic lower respiratory diseases (Z82.5), arthritis and other diseases of the musculoskeletal system and connective tissue (Z82.6), congenital malformations, deformations and chromosomal abnormalities (Z82.7) and other disabilities and chronic diseases leading to disablement, not elsewhere classified (Z82.8).

To report this condition, pick the subcode that matches the documentation: Z82.41 (death) and Z82.49 (system).

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