Inhalant dependence with intoxication delirium

This code signifies a severe pattern of inhalant use characterized by physiological and psychological dependence, coupled with the acute onset of delirium directly attributable to inhalant intoxication. Patients exhibit significant impairment in cognition, perception, and consciousness, developing rapidly over a short period.

Apply this code when documentation clearly indicates both inhalant dependence and an acute confusional state (delirium) caused by recent inhalant use. Supporting documentation should detail the patient's history of inhalant abuse, symptoms consistent with dependence (e.g., tolerance, withdrawal), and the specific features of delirium observed during the encounter.

• Ensure documentation explicitly links the delirium to inhalant intoxication, ruling out other causes.
• Do not use this code if dependence is not clearly established; consider codes for inhalant abuse with intoxication delirium (F18.121).
• Sequence this code as the primary diagnosis when it is the main reason for the encounter, followed by codes for any associated physical complications.
