Inhalant dependence with inhalant-induced dementia

This code signifies a severe form of inhalant use disorder characterized by a physiological and psychological dependence on inhalants, coupled with the development of dementia directly attributable to the chronic inhalant abuse. The patient exhibits cognitive decline, memory impairment, and other neurological deficits resulting from the neurotoxic effects of inhalants.

Apply this code when documentation clearly indicates a diagnosis of inhalant dependence and a co-occurring diagnosis of dementia, with a definitive causal link established between the inhalant use and the dementia. This typically requires a physician's assessment confirming both the dependence and the inhalant-induced cognitive impairment.

• Ensure documentation explicitly states "inhalant-induced dementia" or similar phrasing to support the causal link.
• Do not use this code if the dementia is due to another cause, even if inhalant dependence is also present.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter, followed by codes for specific manifestations of the dementia if applicable.
