ICD-10 Code F12.120 – Cannabis abuse with intoxication, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.120 – Cannabis abuse with intoxication, uncomplicated
What it is
This code identifies cannabis abuse accompanied by acute intoxication, without documented complications. Use it when the record shows harmful cannabis use and current intoxication, but no delirium, psychosis, or other specified complication.
Clinical signs
Typical findings include recent cannabis use with altered mood, impaired coordination, slowed reaction time, or decreased attention. Clinical features vary; refer to documentation.
When to use this code
Use F12.120 when the provider documents cannabis abuse and intoxication in the same encounter. It fits emergency, urgent care, or outpatient notes describing intoxication without a more specific cannabis-related disorder. If the chart does not clearly state abuse or intoxication, check documentation.
Do not use for
Do not use this code for cannabis dependence, uncomplicated cannabis use, or intoxication with delirium or psychotic disorder. Check documentation if the note describes a different cannabis-related diagnosis.
Coding tip
Assign the most specific cannabis-related code documented, and verify that “uncomplicated” is supported by the record.
