Inhalant use, unsp with inhalant-induced persisting dementia

This code signifies a diagnosis of dementia that is directly caused by the chronic or acute use of inhalant substances, where the specific type of inhalant is not documented. The cognitive impairment is persistent, indicating a lasting neurological effect from the inhalant exposure.

Apply this code when documentation clearly links a patient's persistent dementia to inhalant use, but the specific inhalant (e.g., toluene, gasoline) is not specified. This code is appropriate when a physician's assessment or neurological evaluation confirms inhalant-induced cognitive decline.

• Ensure documentation explicitly states "inhalant-induced" and "persisting dementia."
• Do not use if the specific inhalant is known; instead, use a more specific F18.xx7 code.
• Sequence this code as a primary diagnosis if the dementia is the focus of the encounter, or as a secondary diagnosis if managing another condition alongside the dementia.
