ICD-10 Code F12 – Cannabis Related Disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12 – Cannabis related disorders
What it is
F12 identifies disorders related to cannabis use, including abuse, dependence, and other cannabis-induced conditions. Use it when the record documents a cannabis-related mental or behavioral disorder.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include problematic cannabis use, impaired control, or cannabis-associated intoxication, withdrawal, or mental changes.
When to use this code
Use F12 when the provider documents a cannabis-related disorder and does not specify a more detailed subcategory in the record. Code it for diagnoses tied to cannabis use or cannabis-induced symptoms when supported by the note.
If the chart only mentions use without a disorder, check documentation before assigning this code. Confirm whether the condition is abuse, dependence, or another cannabis-related diagnosis.
Do not use for
Do not use F12 for simple history of cannabis use, screening, or an unrelated condition. Check documentation if the note does not clearly identify a cannabis-related disorder.
Coding tip
Always code the most specific F12 subcategory documented, and verify whether the provider linked the condition to cannabis use.
