ICD-10 Code F12.12 – Cannabis abuse with intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.12 – Cannabis abuse with intoxication
What it is
Use this code for cannabis abuse when the patient is currently intoxicated from cannabis. It identifies harmful use with acute effects, not simple use or dependence.
Clinical signs
Clinical features vary; refer to documentation. Typical intoxication may include impaired judgment, altered attention, slowed reaction time, euphoria, anxiety, or other acute behavioral changes after cannabis use.
When to use this code
Assign F12.12 when the record clearly documents cannabis abuse with intoxication. Use it for visits where the provider links the acute presentation to cannabis intoxication and describes abuse rather than dependence or uncomplicated use.
Check documentation for the substance, the intoxicated state, and any associated mental or behavioral changes. If the note only says cannabis use, this code is not supported.
Do not use for
Do not use this code for cannabis dependence, uncomplicated cannabis use, or a history of use without intoxication. If the documentation is unclear, check documentation.
Coding tip
Code the highest level of specificity documented, and confirm that abuse and intoxication are both stated in the record.
