Other psychoactv substance abuse with withdrawal, unsp

This code signifies a pattern of maladaptive use of a psychoactive substance, other than alcohol, opioids, cannabis, sedatives/hypnotics, cocaine, or stimulants, that leads to clinically significant impairment or distress, and is accompanied by withdrawal symptoms. The specific psychoactive substance is not identified in the medical record.

Apply this code when documentation clearly indicates abuse of an unspecified psychoactive substance and the patient is experiencing withdrawal symptoms. This is appropriate when the provider has diagnosed substance abuse and withdrawal, but the specific substance cannot be further clarified (e.g., "polysubstance abuse with withdrawal, unspecified substance").

• Ensure documentation explicitly states "abuse" and "withdrawal" for an unspecified psychoactive substance.
• Avoid using this code if the specific substance (e.g., hallucinogens, inhalants) is known; instead, use the more specific F16.139 or F18.139.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
