Oth psychoactive substance abuse with intoxication delirium

This code signifies a pattern of problematic psychoactive substance use, excluding alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, cocaine, and other stimulants, leading to clinically significant impairment or distress. The patient is experiencing a delirium directly attributable to the intoxicating effects of this substance.

Apply this code when documentation clearly indicates abuse of a psychoactive substance not specified elsewhere, coupled with an acute confusional state (delirium) during intoxication. This requires a physician's diagnosis of both substance abuse and substance-induced delirium, with a direct causal link established.

• Ensure the documentation specifies "abuse" rather than "dependence" or "use" to accurately assign this code.
• Verify that the delirium is explicitly linked to the intoxication and not another underlying medical condition.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated physical manifestations.
