ICD-10 Code F19.950 – Other psychoactive substance use, unspecified with psychoactive substance-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.950 – Other psychoactive substance use, unspecified with psychoactive substance-induced psychotic disorder with delusions
What it is
This code identifies psychosis with delusions caused by use of an unspecified psychoactive substance. It indicates the substance-related mental disorder, not a primary psychotic illness.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include delusions, altered thought content, and evidence that symptoms developed in the context of psychoactive substance use.
When to use this code
Use this code when the record documents an unspecified psychoactive substance and a substance-induced psychotic disorder with delusions. Apply it when the clinician links the psychosis to substance use and does not name a more specific substance.
Code from the provider’s diagnosis, history, and assessment. If the documentation only says psychosis or substance use without the delusional disorder link, check documentation.
Do not use for
Do not use this code for primary psychotic disorders, such as schizophrenia, or when the substance is identified by a more specific ICD-10-CM code. Check documentation if the causal relationship is unclear.
Coding tip
Confirm both the unspecified substance and the substance-induced psychotic disorder with delusions are documented before assigning F19.950.
