ICD-10 Code F15.180 – Other Stimulant Abuse with Stimulant-Induced Anxiety Disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.180 – Other stimulant abuse with stimulant-induced anxiety disorder
What it is
This code identifies stimulant abuse, such as amphetamine-type or other stimulant use, when the patient also has anxiety caused by the stimulant. Use it when the anxiety is directly linked to the substance use.
Clinical signs
Patients may show nervousness, restlessness, excessive worry, panic-like symptoms, or agitation after stimulant use. Clinical features vary; refer to documentation, and confirm the anxiety is substance-induced rather than a separate anxiety disorder.
When to use this code
Use this code when the record documents stimulant abuse and the clinician states that anxiety is caused by the stimulant. It applies when the anxiety occurs during or soon after use and is not better explained by another mental health diagnosis. Check documentation if the substance type or causal link is unclear.
Do not use for
Do not use it for stimulant dependence without abuse, or for anxiety disorders that are unrelated to substance use. Do not assign it when the chart only notes stimulant use without documented anxiety.
Coding tip
Code both the stimulant abuse and the substance-induced anxiety only when the provider clearly links the anxiety to the stimulant.
