Oth psychoactive substance dependence w intoxication, uncomp

This code signifies a patient's physiological or psychological dependence on a psychoactive substance other than alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, cocaine, or stimulants, who is currently experiencing acute intoxication without complications. The dependence is characterized by a pattern of compulsive use and withdrawal symptoms upon cessation.

Apply this code when documentation clearly indicates a diagnosis of dependence on an unspecified psychoactive substance, and the patient presents with symptoms of acute intoxication. Supporting documentation should detail the substance class (if known but not specific enough for other F1x.2 codes) and confirm the absence of delirium, psychotic features, or other specified complications.

• Ensure the documentation specifies "dependence" and "intoxication" for an unspecified psychoactive substance.
• Do not use this code if the substance is clearly identified as alcohol, opioids, cannabis, etc.; instead, use the more specific F1x.22x code.
• Always sequence this code first if it is the primary reason for the encounter and the intoxication is acute.
