Diagnosis. The term diagnosis means any reference to an individual's alcohol or drug abuse or to a condition which is identified as having been caused by that abuse or any reference to sickle cell anemia or infection with the human immunodeficiency virus which is made for the purpose of treatment or referral for treatment.
