About the Z81 Code Range
A family history of mental or behavioral disorders describes conditions in a person's family, rather than a condition the person has.
Z81 separates intellectual disabilities from substance abuse and dependence and from other mental or behavioral disorders. The substance-related subdivisions distinguish alcohol, tobacco, other psychoactive substances, and other substances.
