ICD-10 Code F12.90 – Cannabis use, unspecified, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.90 – Cannabis use, unspecified, uncomplicated
What it is
F12.90 identifies cannabis use without a more specific subtype, complication, or associated disorder documented. Use it when the record confirms cannabis use but does not specify intoxication, dependence, abuse, or cannabis-induced conditions.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of cannabis use, self-report, positive history, or related behavioral concerns, but the chart should not support a more specific cannabis diagnosis.
When to use this code
Use this code when the provider documents cannabis use and leaves the diagnosis unspecified or uncomplicated. It also fits when the note does not distinguish between use, abuse, or dependence, and no cannabis-related disorder is recorded. Check documentation if another F12 category is supported.
Do not use for
Do not use F12.90 for cannabis dependence, abuse, intoxication, withdrawal, or cannabis-induced disorders. If the record names a specific complication or disorder, code that condition instead.
Coding tip
Confirm the provider’s wording; “use” alone supports F12.90 only when no more specific cannabis diagnosis is documented.
