ICD-10 Code F12.18 – Cannabis abuse with other cannabis-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.18 – Cannabis abuse with other cannabis-induced disorder
What it is
This code identifies cannabis abuse accompanied by another cannabis-induced disorder. Use it when documentation shows problematic cannabis use plus a separate disorder caused by cannabis, not just intoxication or uncomplicated abuse.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of impaired functioning, recurrent use despite harm, and symptoms linked to a cannabis-induced condition such as mood, anxiety, psychotic, or sleep disturbance.
When to use this code
Use F12.18 when the record clearly states cannabis abuse and also documents another cannabis-induced disorder. This applies when the provider links the secondary condition to cannabis use and does not document dependence instead. Check documentation if the induced disorder is unspecified.
Do not use for
Do not use this code for uncomplicated cannabis abuse, cannabis dependence, or cannabis intoxication alone. Also avoid it when the record does not support a separate cannabis-induced disorder.
Coding tip
Confirm both elements in the note: cannabis abuse and the specific cannabis-induced disorder.
