ICD-10 Code F12.180 – Cannabis abuse with cannabis-induced anxiety disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.180 – Cannabis abuse with cannabis-induced anxiety disorder
What it is
Use this code for cannabis abuse accompanied by an anxiety disorder caused by cannabis use. It identifies a substance-related anxiety condition rather than primary anxiety alone.
Clinical signs
Clinical features may include excessive worry, panic, restlessness, or fear that begins during or soon after cannabis use. Clinical features vary; refer to documentation.
When to use this code
Use F12.180 when the record clearly states cannabis abuse and cannabis-induced anxiety disorder. Code it when the clinician links the anxiety symptoms to cannabis use, not to another mental health diagnosis.
If documentation only says cannabis use with anxiety, check whether the provider identified abuse and a substance-induced disorder. If the causal relationship is unclear, check documentation.
Do not use for
Do not use this code for primary anxiety disorders without cannabis involvement. Also avoid it when the chart documents cannabis dependence, use without abuse, or anxiety caused by another substance.
Coding tip
Confirm both the abuse diagnosis and the substance-induced anxiety link in the provider note before assigning F12.180.
