ICD-10 Code F12.150 – Cannabis abuse with psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.150 – Cannabis abuse with psychotic disorder with delusions
What it is
This code identifies cannabis abuse accompanied by a psychotic disorder in which delusions are present. Use it when the record links cannabis use to psychotic symptoms and specifically documents delusional thinking.
Clinical signs
Typical findings include fixed false beliefs, impaired reality testing, and behavior consistent with psychosis. Clinical features vary; refer to documentation for the exact presentation and whether the delusions are attributable to cannabis use.
When to use this code
Use this code when the provider documents cannabis abuse and a psychotic disorder with delusions in the same encounter or assessment. It is appropriate when the record clearly states that the psychotic condition is associated with cannabis use. If the documentation is unclear, check documentation before coding.
Do not use for
Do not use this code for cannabis use without abuse, or for psychosis without documented delusions. Also avoid it when another substance, medical condition, or primary psychotic disorder is identified as the cause.
Coding tip
Code only when the provider explicitly links cannabis abuse to psychotic disorder with delusions.
