Inhalant related disorders (F18)
ICD-10 codes F18 cover disorders related to the misuse of inhalants, substances commonly abused through sniffing, huffing, or smoking. These codes specify various patterns of inhalant abuse, dependence, and use, including associated mental health effects.
The section includes codes for uncomplicated inhalant abuse (also called "abuses volatile solvents" or "sniffs drugs"), inhalant dependence such as "glue sniffing dependence," and unspecified inhalant use. It further distinguishes conditions with complications like intoxication, delirium, mood disorders, psychotic disorders with delusions or hallucinations, dementia, anxiety disorders, and other inhalant-induced disorders. For example, F18.10 identifies uncomplicated inhalant abuse, while F18.15 addresses inhalant abuse with psychotic disorder. Codes like F18.21 mark remission states, and unspecified use codes (e.g., F18.9) are included for unclear or unspecified conditions. The wide range of ICD-10 codes for inhalant-related disorders ensures accurate coding for clinical documentation involving volatile solvent abuse and its psychiatric and neurological consequences.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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.
