ICD-10 Code F15.94 – Other Stimulant Use, Unspecified with Stimulant-Induced Mood Disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.94 – Other stimulant use, unspecified with stimulant-induced mood disorder
What it is
This code identifies stimulant use, not otherwise specified, with a mood disorder caused by the stimulant. Use it when the mood symptoms are documented as substance-induced rather than a primary psychiatric disorder.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see depressed mood, elevated mood, irritability, or marked emotional lability linked to stimulant use or withdrawal.
When to use this code
Use this code when the record clearly states stimulant use is associated with a stimulant-induced mood disorder and no more specific stimulant category is documented. It fits cases where the clinician links the mood disturbance to stimulant exposure. Check documentation if the substance type, severity, or timing is unclear.
Do not use for
Do not use it for a primary mood disorder unrelated to substance use, or when the stimulant is identified more specifically and another code applies. Do not use if documentation does not support a substance-induced condition.
Coding tip
Code the stimulant-related mood disorder only when the provider explicitly documents the causal link.
