Oth psychoactv substance depend w psych disorder w delusions

This code signifies a patient's physiological and psychological dependence on a psychoactive substance (excluding alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, cocaine, stimulants, and hallucinogens) that has led to a psychotic disorder characterized by delusions. The substance use is compulsive and difficult to control, and the resulting psychosis manifests as fixed, false beliefs.

Apply this code when documentation clearly indicates dependence on a "catch-all" psychoactive substance (e.g., inhalants, phencyclidine, or other specified psychoactive substances not covered by more specific categories) and a co-occurring substance-induced psychotic disorder with delusions. Supporting documentation should include a definitive diagnosis of dependence and a description of the delusional symptoms directly attributed to the substance use.

• Always code the specific psychoactive substance if known and a more granular code exists (e.g., F11.250 for opioid dependence).
• Ensure the documentation explicitly links the psychotic disorder with delusions to the psychoactive substance use, rather than an independent psychiatric condition.
• Sequence this code as a primary diagnosis when it is the focus of treatment, or as a secondary diagnosis when addressing the substance-induced psychosis in the context of other conditions.
