Oth psychoactive substance dependence w anxiety disorder

This diagnosis code signifies a patient's physiological and psychological dependence on a psychoactive substance (other than alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, stimulants, or hallucinogens) that has directly induced an anxiety disorder. The anxiety symptoms are a direct physiological consequence of the substance use or withdrawal.

Apply this code when documentation clearly indicates a diagnosis of dependence on a specified psychoactive substance (e.g., inhalants, phencyclidine, or multiple substance use where none predominates) and a co-occurring anxiety disorder that is explicitly attributed to the substance's effects. Clinical notes should specify both the substance dependence and the substance-induced anxiety.

• Ensure the documentation explicitly links the anxiety disorder to the psychoactive substance use or withdrawal.
• Do not use this code if the anxiety disorder predates the substance use or is clearly unrelated.
• Always code the specific psychoactive substance dependence if known and available in the F10-F19 range.
