Oth psychoactive substance use, unsp w intoxication, uncomp

This code signifies a patient presenting with symptoms of intoxication due to the use of a psychoactive substance that is not specified or identifiable. The intoxication is uncomplicated, meaning there are no co-occurring medical or psychiatric complications directly attributable to the substance use at the time of encounter. This diagnosis indicates an acute state of altered mental or physical function caused by the substance.

Apply this code when documentation clearly indicates intoxication from a psychoactive substance, but the specific substance (e.g., opioid, cannabis, stimulant) is not identified. This is appropriate for situations where the patient's history or toxicology screens are unavailable or inconclusive regarding the exact substance. Supporting documentation would include clinical notes describing signs and symptoms of intoxication without further complications.

• Do not use this code if the specific psychoactive substance is known; instead, use the more specific code for that substance (e.g., F11.920 for opioid intoxication).
• Ensure documentation explicitly states "uncomplicated" or lacks any mention of complications (e.g., delirium, withdrawal, psychosis) directly linked to the intoxication.
• Consider sequencing this code as a primary diagnosis if the intoxication is the main reason for the encounter, or as a secondary diagnosis if it's an associated condition.
