Inhalant use, unspecified with intoxication, unspecified

This code signifies a diagnosis of inhalant use disorder where the specific inhalant substance is not documented, and the patient is experiencing symptoms of intoxication without further specification of the intoxication's severity or manifestation. It indicates an acute state of altered mental or physical function due to recent inhalant exposure.

Apply this code when documentation clearly states inhalant use with intoxication, but the specific inhalant (e.g., toluene, gasoline) is not identified, and the intoxication symptoms are not detailed beyond the general presence of intoxication. This is often used in emergency department settings or initial assessments where full substance identification or symptom specificity is pending.

• Avoid using this code if the specific inhalant substance is known; instead, use a more specific code from the F18.1-F18.2 series.
• Do not use if there is no documentation of intoxication; consider codes for inhalant use without intoxication (e.g., F18.90).
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-occurring condition impacting treatment.
