What This Code Means

A person who is dependent on inhalants (unable to stop using them despite wanting to) without any current complications or other related disorders.

Coding Tips

•This code indicates dependence without intoxication or other specified complications
•Distinguish between abuse (F18.1x) and dependence (F18.2x) based on loss of control and continued use despite harm

Clinical Significance

Inhalant dependence represents a severe substance use disorder with compulsive use, tolerance, and/or withdrawal despite harmful consequences. Inhalant dependence is particularly dangerous because chronic exposure causes cumulative neurotoxicity, hepatotoxicity, nephrotoxicity, and cardiotoxicity with risk of sudden death.

✓Provider documentation explicitly using the term 'dependence'
✓Evidence of dependence criteria: tolerance, withdrawal, compulsive use, inability to cut down
✓Type of inhalant(s) used when known
✓Assessment of end-organ damage (neurologic, cardiac, hepatic, renal)
✓Statement that dependence is currently uncomplicated (no active intoxication or induced disorders)
✓Treatment plan including rehabilitation and monitoring
