2026 ICD-10-CM Diagnosis Code F19.159 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder, unspecified
What it is
This code identifies abuse of another psychoactive substance when the person also has a substance-induced psychotic disorder, but the specific psychotic features are not further specified. Use it when documentation links the psychosis to the substance.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported psychotic findings may include hallucinations, delusions, disorganized thinking, or impaired reality testing occurring in the setting of substance use.
When to use this code
Use this code when the record states both psychoactive substance abuse and a psychotic disorder caused by that substance, and no more specific psychotic subtype is documented. It is appropriate when the substance is not named more specifically in the code description. If the chart identifies a different substance or a more specific psychotic disorder, check documentation before assigning this code.
Do not use for
Do not use this code if psychosis is unrelated to substance use or if the documentation supports dependence, use, or intoxication without psychotic disorder. Do not guess the substance or psychotic subtype.
Coding tip
Confirm that the provider explicitly connects the psychosis to substance abuse and that no more specific code is documented.
