ICD-10 Code F15.90 – Other Stimulant Use, Unspecified, Uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.90 – Other stimulant use, unspecified, uncomplicated
What it is
F15.90 identifies stimulant use that is documented, but the specific stimulant is not named and no complication is documented. Use it when the record supports stimulant use without a more detailed diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Notes may mention stimulant use, misuse, or dependence-related concerns, but this code does not specify intoxication, withdrawal, or a stimulant-related disorder.
When to use this code
Use F15.90 when the provider documents other stimulant use and does not name the substance, such as amphetamine-type or similar stimulants, and no complication is recorded. It also fits brief problem-list entries or assessment notes that confirm use without further detail.
If the chart later identifies the stimulant or a related condition, code the more specific diagnosis instead. Check documentation for whether the use is uncomplicated or linked to intoxication, withdrawal, or another substance-related disorder.
Do not use for
Do not use this code for stimulant intoxication, withdrawal, or stimulant-induced mental or physical disorders. It is also wrong when the record names the specific stimulant and a more precise ICD-10-CM code is available.
Coding tip
Before assigning F15.90, confirm the stimulant is unspecified and the documentation does not describe a complication or a more specific stimulant-related diagnosis.
