What This Code Means

A condition where someone abuses various drugs and develops excessive worry, panic, or anxiety symptoms that are directly caused by the substance use.

Coding Tips

• •Specify the type of anxiety disorder (generalized anxiety, panic disorder, etc.) when documented
• •Confirm anxiety symptoms are substance-induced rather than a pre-existing anxiety disorder

Clinical Significance

This code identifies substance-induced anxiety disorder from other psychoactive substance abuse, where anxiety symptoms are a direct pharmacological consequence of the substance. This dual diagnosis increases treatment complexity and resource utilization compared to either condition alone. Accurate capture supports risk stratification reflecting the combined behavioral health burden.

Documentation Requirements

• ✓Provider documentation specifying the psychoactive substance(s) involved (e.g., designer drugs, bath salts, kratom, polysubstance use)
• ✓Clinical documentation supporting substance abuse pattern (maladaptive use pattern causing clinically significant impairment) without meeting criteria for dependence
• ✓Documentation of anxiety symptoms (panic attacks, generalized anxiety, obsessive-compulsive features) with explicit causal link to the substance use
• ✓Evidence that anxiety symptoms are not better explained by a primary anxiety disorder
• ✓Assessment and plan addressing the substance use disorder with treatment approach documented
