Coding Tips

- •Ensure anxiety disorder is documented as inhalant-induced rather than a separate primary condition
Clinical Significance
Inhalant abuse with induced anxiety disorder captures anxiety symptoms (panic, generalized anxiety, phobic responses) directly caused by inhalant exposure. Inhalants affect GABA and glutamate neurotransmission, which can produce significant anxiety states requiring integrated addiction and psychiatric treatment.

- ✓Documentation of inhalant abuse
- ✓Specific anxiety symptoms documented
- ✓Provider statement that anxiety is induced by inhalant use
- ✓Temporal relationship between inhalant exposure and anxiety
- ✓Type of inhalant when identifiable
