Z82

Z82 is a classification code within the ICD-10-CM medical coding system used in the United States to denote a patient’s family history of certain diseases and health conditions. It belongs to the Z codes, which cover factors influencing health status and contact with health care services. Codes in the Z82 category are not conditions themselves but documentation about inherited risk or familial recurrence. They are used to convey information about relatives’ medical histories that may be relevant to the patient’s health, risk assessment, screening decisions, and preventive care.

The category is applied when a clinician documents that a disease or condition runs in the patient’s family. Z82 codes may be used in conjunction with codes describing the patient’s current problems. The exact code chosen depends on the specific disease or condition identified in the family history. For instance, a note indicating a family history of cancer, cardiovascular disease, or metabolic disorders may be coded under Z82, with the specific subcode reflecting the particular condition described.

Coding considerations include ensuring that the history is familial and not the patient’s current condition, and that documentation supports the relation and disease. Z82 entries are commonly used in preventive services, risk assessment, and epidemiological data collection. Related ICD-10-CM categories cover other aspects of health history and risk factors, including personal health history and other family history codes.
