ICD-10 Code F15.18 – Other stimulant abuse with other stimulant-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.18 – Other stimulant abuse with other stimulant-induced disorder
What it is
F15.18 identifies abuse of a stimulant with a separate stimulant-induced disorder. Use it when the record shows harmful stimulant use plus another mental or physical condition caused by that use.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe stimulant misuse with related symptoms such as agitation, anxiety, mood changes, or other substance-induced effects.
When to use this code
Use this code when the clinician documents stimulant abuse and specifies an additional stimulant-induced disorder, but the exact induced condition is not otherwise classified. Confirm that both the abuse and the induced disorder are documented.
If the chart only says stimulant use without abuse, or describes dependence or intoxication instead, this code is not the best choice. Check documentation for the most specific diagnosis available.
Do not use for
Do not use it for uncomplicated stimulant abuse without an induced disorder. Also avoid it when the record supports stimulant dependence, intoxication, or a different substance-induced diagnosis.
Coding tip
Code the induced disorder only when the provider clearly links it to stimulant abuse and documents the relationship.
