Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the F18 range.
Inhalant Abuse
Illicit use of chemicals and products whose vapors can be inhaled to produce a rapid mind-altering effect. Inhalants include aerosols, gases, and volatile solvents that are often inhaled repeatedly to achieve the short-lived intoxicating effect.
About the F18 Code Range
Glue sniffing dependence and intoxication caused by inhalants are among the conditions described here. The codes also describe inhalant abuse and unspecified inhalant use.
The main branches separate F18.1 abuse, F18.2 dependence, and F18.9 unspecified use. Within each branch, codes distinguish uncomplicated cases, remission, intoxication, and inhalant-induced disorders involving mood, psychosis, dementia, anxiety, or other effects. Intoxication codes distinguish delirium from uncomplicated or unspecified intoxication. Psychotic disorder codes distinguish delusions, hallucinations, and unspecified symptoms.
