ICD-10 Code F15.98 – Other stimulant use, unspecified with other stimulant-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.98 – Other stimulant use, unspecified with other stimulant-induced disorder
What it is
This code identifies stimulant use, but the exact stimulant is not specified, along with another stimulant-induced disorder. Use it when the record links the substance use to a separate stimulant-related mental or behavioral condition.
Clinical signs
Clinical features vary; refer to documentation. Records may describe stimulant-related mood, psychotic, anxiety, or sleep disturbance, together with evidence of use of an unspecified stimulant.
When to use this code
Use this code when the clinician documents stimulant use and a separate stimulant-induced disorder, but does not name the stimulant. It is appropriate when the chart supports a causal relationship between the stimulant use and the induced condition. Check documentation if the induced disorder is not clearly stated.
Do not use for
Do not use this code for stimulant intoxication, withdrawal, or uncomplicated use without an induced disorder. If the stimulant is identified and a more specific code applies, code that instead.
Coding tip
Confirm both the unspecified stimulant use and the specific stimulant-induced disorder are documented before assigning F15.98.
