Oth psychoactive substance use, unsp with intoxication, unsp

This code signifies a patient presenting with signs and symptoms of intoxication due to the use of a psychoactive substance that is not specified or identifiable. The specific substance and the nature of the intoxication are both undetermined. This diagnosis indicates an acute state of altered mental or physical functioning resulting from substance use.

Use this code when documentation clearly indicates intoxication from a psychoactive substance, but the specific substance cannot be identified, and the type of intoxication is also not specified. This is often applicable in emergency department settings where a patient is acutely intoxicated, and a definitive substance or intoxication type has not yet been determined through toxicology screens or patient history.

• Avoid using this code if a more specific psychoactive substance (e.g., opioid, cannabis, stimulant) or type of intoxication (e.g., delirium, hallucinogen-induced psychotic disorder) is documented.
• Always strive for greater specificity if available; this code represents a lack of detailed information.
• Consider sequencing this code as a primary diagnosis when the intoxication is the primary reason for the encounter.
