ICD-11 6D70.1 — Delirium due to psychoactive substances including medications

All definitional requirements for delirium are met. There is evidence from history, physical examination, or laboratory findings that the delirium is caused by the direct physiological effects of a substance or medication (including withdrawal). If the specific substance inducing the delirium has been identified, it should be classified using the appropriate subcategory (e.g., alcohol-induced delirium).

The diagnosis includes nothing.
