V18.8
ICD-9-CMThis code indicates a patient's family history of infectious or parasitic diseases, meaning a close blood relative has or had such a condition. It signifies a genetic predisposition or shared environmental exposure that may increase the patient's risk for similar conditions.
Apply this code when a patient's medical record documents a family history of conditions like tuberculosis, HIV, hepatitis, or other communicable diseases. This is particularly relevant during preventive care visits, risk assessments, or when evaluating a patient with symptoms that could be linked to a familial infectious disease.
