ICD-10 Code F15.980 – Other stimulant use, unspecified with stimulant-induced anxiety disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.980 – Other stimulant use, unspecified with stimulant-induced anxiety disorder
What it is
This code identifies anxiety disorder caused by stimulant use, when the stimulant is not further specified and the record does not name a more exact stimulant-related diagnosis. Use it for anxiety symptoms linked to stimulant exposure.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include anxiety, nervousness, restlessness, and related symptoms that begin during or after stimulant use and are judged to be substance-induced.
When to use this code
Use this code when the provider documents stimulant use with an anxiety disorder and does not identify a more specific stimulant or stimulant-related condition. It also fits when the chart states “other stimulant use” and links the anxiety disorder to that use.
Code from the provider’s diagnosis, not from suspicion alone. If the note does not clearly connect the anxiety disorder to stimulant use, check documentation before assigning F15.980.
Do not use for
Do not use this code for primary anxiety disorders unrelated to substances, or when the stimulant-induced condition is documented with a more specific ICD-10-CM code. Check documentation if the substance relationship is unclear.
Coding tip
Confirm both the stimulant association and the anxiety diagnosis in the same record before coding F15.980.
