ICD-10 Code F12.929 – Cannabis use, unspecified with intoxication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.929 – Cannabis use, unspecified with intoxication, unspecified
What it is
This code identifies cannabis use with intoxication when the provider does not document a specific type of intoxication. Use it when the record confirms cannabis involvement but the detail is limited.
Clinical signs
Clinical features vary; refer to documentation. Intoxication may include altered perception, impaired coordination, slowed reaction time, anxiety, or other acute behavioral changes after cannabis use.
When to use this code
Use this code when the clinician documents cannabis use and intoxication, but does not specify the intoxication type. It fits encounters where the chart supports acute cannabis effects and no more specific code is documented. Check documentation if the record also mentions abuse, dependence, or another substance.
Do not use for
Do not use this code for cannabis use without intoxication, or when the record clearly documents a different cannabis-related disorder. If the substance or clinical state is unclear, check documentation.
Coding tip
Match the code to the documented cannabis status and intoxication detail; if the provider gives a more specific term, code that instead.
