Family history of other conditions (Z84)

ICD-10 code Z84 and its subcategories are used to document a patient’s family history of various medical conditions. These codes help record hereditary or familial factors relevant to diagnosis, treatment, or risk assessment.

The Z84.0 code covers family history of skin diseases like scleroderma, psoriasis, eczema, and lupus, among others. Z84.1 refers to a family history of kidney and ureter disorders such as renal stones and nephrotic syndrome. Z84.2 captures family history relating to other genitourinary diseases, including infertility, polycystic ovary syndrome, and benign prostatic hyperplasia. The code Z84.3 denotes family history of consanguinity. More specific conditions include Z84.81 for family history of being a carrier of genetic diseases like BRCA gene mutations and Lynch syndrome, and Z84.82 for family history of sudden infant death syndrome. The broader codes Z84.8 and Z84.89 cover family history of other specified conditions such as neoplasms, neonatal death, allergies, and a variety of inherited or familial disorders. Using these codes ensures precise documentation and improves understanding of genetic and familial risks in patient care.
