ICD-10 Code F12.1 – Cannabis abuse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.1 – Cannabis abuse
What it is
F12.1 identifies cannabis abuse, meaning a problematic pattern of cannabis use that causes impairment or distress. Use it when the record supports abuse rather than dependence or uncomplicated use.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note recurrent use despite social, work, or legal problems, or continued use despite known harm.
When to use this code
Use F12.1 when the clinician documents cannabis abuse, harmful use, or a similar nondependent pattern of use. It may also fit when the note describes consequences from use without criteria for dependence. If the documentation is unclear, check documentation before coding.
Do not use for
Do not use this code for cannabis dependence, uncomplicated cannabis use, or intoxication states. If the chart only shows history of use without current abuse, select a more appropriate code.
Coding tip
Code only what the provider documents, and confirm whether the record supports abuse versus dependence or simple use.
