Cannabis Use Disorder ICD-10 Code
If you’re looking at medical records, insurance paperwork, or a diagnosis note, Cannabis Use Disorder shows up under a specific set of ICD-10 codes rather than a single number — which code applies depends on severity and whether the person is in remission.
The main codes
Cannabis-related disorders fall under the F12 category. F12.10 covers Cannabis Use Disorder, mild. F12.20 covers moderate to severe cannabis use disorder. From there, additional digits specify complications — F12.21 for use disorder in remission, F12.220 for cannabis dependence with intoxication, and so on. The exact code a provider uses depends on the clinical picture, not just the presence of use.
Why the code matters practically
ICD-10 codes drive insurance billing and treatment authorization, and they end up in a patient’s permanent medical record. Getting the right code matters for continuity of care — it’s part of why an accurate diagnosis, not just a general note about cannabis use, is worth pursuing with a provider.
Related codes worth knowing
If cyclical vomiting is part of the clinical picture, that’s typically coded separately from the substance use disorder itself, since Cannabinoid Hyperemesis Syndrome is its own diagnosis. Both codes can appear on the same chart when both conditions are present, which is common in people with long-term heavy use.
FAQ
Is there one single ICD-10 code for cannabis use disorder?
No — the code depends on severity (mild vs. moderate/severe) and additional specifiers like remission status or co-occurring intoxication.
Does the code affect insurance coverage for treatment?
It can. Insurers often use the specific code and severity level to determine what level of treatment is authorized.
