Inhalant abuse with inhalant-induced dementia

This code signifies a diagnosis of inhalant abuse that has resulted in the development of dementia. It describes a neurocognitive disorder directly attributable to the chronic misuse of inhalant substances, characterized by significant cognitive decline affecting memory, executive function, and other domains.

Apply this code when documentation clearly indicates a patient's cognitive impairment meets the criteria for dementia, and a direct causal link is established between this impairment and the patient's history of inhalant abuse. This typically involves a psychiatric evaluation confirming both the substance abuse and the resulting neurocognitive disorder.

• Ensure documentation explicitly states "inhalant-induced dementia" or similar phrasing linking the dementia directly to inhalant abuse.
• Do not use this code if the dementia is due to other causes, even if inhalant abuse is present.
• Consider co-reporting with codes for specific inhalant abuse patterns (e.g., F18.10 for unspecified inhalant abuse) if further detail is documented.
