When you have seen a code such as F15.20 on a chart, insurance form, or discharge summary, you may feel the need to know what that code means, particularly when it concerns you or someone dear to you.
Stimulant use disorder is classified under the ICD-10 as F15 and includes amphetamines, methamphetamine, prescription stimulants, and caffeine. Cocaine is also coded under F14. There are particular codes such as F15.10 (abuse) and F15.20 (dependence) and other characters to specify complications such as intoxication, withdrawal, or remission status.
The coding of stimulant use disorder may be more complex than it has to be, primarily due to the F15 category being divided into such a large number of specific subcodes. Knowing how a diagnosis code is structured in the first place makes it a lot easier to know what the code is actually saying.
This guide will subdivide the ICD-10 codes of stimulant use disorder, the differences between stimulant use disorder and the codes of cocaine, documentation, and what the actual treatment would look like after making the diagnosis.
What is The ICD-10 Code For Stimulant Use Disorder?
The ICD-10 code for stimulant use disorder falls under category F15, labeled “other stimulant related disorders,” which covers amphetamines, methamphetamine, prescription stimulants, and caffeine.
Importantly, cocaine is not included under F15. Cocaine-related disorders have their own separate category, F14, due to how the ICD-10-CM classification system organizes stimulant substances.

F15 Diagnosis Code Breakdown
The F15 diagnosis code breaks down into three main subcategories, each reflecting a different severity or pattern of stimulant use.
Subcategory | Description |
F15.1 | Other stimulant abuse |
F15.2 | Other stimulant dependence |
F15.9 | Other stimulant use, unspecified |
Each of these subcategories then branches further based on additional clinical details, such as whether intoxication, withdrawal, or remission is also present.

Stimulant Use Disorder ICD-10 Code Details
Stimulant use disorder ICD-10 code details get more specific at the fourth and fifth character level, identifying the exact clinical picture being documented.
Under F15.1 (Other stimulant abuse):
- F15.10 – Uncomplicated
- F15.11 – In remission
- F15.12 – With intoxication
- F15.13 – With withdrawal
- F15.14 – With stimulant-induced mood disorder
- F15.15 – With stimulant-induced psychotic disorder
Under F15.2 (Other stimulant dependence):
- F15.20 – Uncomplicated
- F15.21 – In remission
Under F15.9 (Other stimulant use, unspecified):
- F15.90 – Uncomplicated
- F15.99 – With unspecified stimulant-induced disorder
Coding guidance on stimulant use disorder documentation notes that F15.20 maps to DSM-5 moderate and severe amphetamine-type substance use disorder, while F15.10 corresponds to milder presentations meeting fewer diagnostic criteria.
Fact: Stimulant use disorder claims are among the most frequently miscoded diagnoses in behavioral health billing.

Amphetamine Use Disorder Coding
Amphetamine use disorder coding falls specifically under the F15 category, since amphetamines, methamphetamine, and related substances are grouped together rather than given their own separate code family.
This means the following substances are all coded under F15, not their own individual categories:
- Amphetamines
- Methamphetamine
- Prescription stimulants used outside their intended purpose, including methylphenidate and amphetamine salts
- Caffeine, when meeting abuse or dependence criteria
Cocaine remains the notable exception, coded separately under F14 rather than falling under the F15 stimulant category.

Why F15 Coding Accuracy Matters
Why F15 coding accuracy matters comes down to more than administrative box-checking, since it directly affects treatment planning, billing, and continuity of care.
- Insurance reimbursement: Incorrect coding can lead to denied or delayed claims
- Clinical clarity: Accurate codes help other providers understand the full clinical picture at a glance
- Treatment tracking: Consistent documentation supports monitoring progress and treatment adjustments over time
- Avoiding common errors: Confusing cocaine-related codes with F15, or failing to document complications like withdrawal, are frequent coding mistakes
Clinical coding resources note that documentation should clearly differentiate between use, abuse, and dependence, since each reflects a different severity level under the DSM-5 criteria that ICD-10-CM codes are built to reflect.

Stimulant Use Disorder Symptoms
Stimulant use disorder symptoms behind the code reflect the same clinical criteria providers use to determine which specific F15 subcode applies.
Common symptoms considered during diagnosis include:
- Using stimulants in larger amounts or for longer than intended
- Persistent, unsuccessful attempts to cut back
- Significant time spent obtaining, using, or recovering from stimulant use
- Cravings
- Continued use despite social, occupational, or health consequences
- Tolerance, needing more to achieve the same effect
- Withdrawal symptoms when not using
The number of criteria present determines whether a milder abuse code or a more severe dependence code applies to a specific diagnosis.
Expert Advice: Accurate documentation of complications like withdrawal directly affects treatment planning, not just billing.

Stimulant Use Disorder Treatment
Stimulant use disorder treatment typically combines behavioral therapy with medical support, regardless of which specific F15 code applies to an individual diagnosis.
Effective treatment approaches include:
- Assessment: Identifying severity, patterns of use, and any co-occurring conditions
- Medical evaluation: Addressing any physical health complications related to stimulant use
- Behavioral therapy: Cognitive behavioral therapy and contingency management have strong evidence behind them
- Dual diagnosis care: Treating co-occurring mental health conditions alongside stimulant use disorder
- Aftercare planning: Ongoing support to reduce relapse risk after formal treatment
Research on stimulant use disorder consistently identifies behavioral interventions, particularly contingency management, as having strong evidence for supporting recovery, since no medication is currently approved specifically to treat stimulant addiction itself.
Stimulant Use Disorder Treatment Options in Detail
Stimulant use disorder treatment options in detail generally address both the behavioral patterns and any underlying conditions contributing to continued use.
- Individual therapy: Addressing the thought patterns and triggers behind stimulant use
- Group therapy: Peer support and shared accountability throughout recovery
- Family therapy: Rebuilding trust and communication affected by substance use
- Dual diagnosis treatment: Addressing co-occurring anxiety, depression, or other conditions alongside stimulant use
- Relapse prevention planning: Building tools to manage triggers and cravings after treatment ends

FAQs
Is cocaine included under the F15 stimulant code category?
No. Although cocaine is pharmacologically a stimulant, cocaine-related disorders are classified separately under the F14 ICD-10 category. The F15 category applies to other stimulants, such as amphetamines, methamphetamine, and certain stimulant medications, making this a common coding distinction.
What is the difference between F15.1 and F15.2?
F15.1 codes generally describe stimulant abuse, reflecting less severe patterns of problematic use. F15.2 codes indicate stimulant dependence, involving more significant impairment, tolerance, withdrawal, or compulsive use that aligns with more moderate to severe clinical presentations.
Does caffeine fall under the F15 stimulant code?
Yes. ICD-10 classifies caffeine-related disorders within the F15 category because caffeine is considered a stimulant. However, clinically significant caffeine-related diagnoses are relatively uncommon compared with disorders involving amphetamines, methamphetamine, or other stimulant substances.
How is stimulant withdrawal coded differently from stimulant abuse alone?
ICD-10 uses more specific codes to identify stimulant withdrawal when it occurs alongside stimulant use disorders. For example, codes such as F15.13 indicate stimulant abuse with withdrawal, documenting both the underlying disorder and the presence of withdrawal symptoms.
Can a provider use an unspecified stimulant code if the exact substance isn’t confirmed?
Yes. Unspecified F15.9 codes are appropriate when stimulant use is documented but the exact substance, diagnosis, or clinical details have not yet been fully established. Providers may later update the code as additional information becomes available.
Why are stimulant use disorder claims frequently miscoded?
Coding errors commonly occur when cocaine disorders are mistakenly assigned F15 codes instead of F14, when complications like withdrawal or intoxication are omitted, or when documentation does not clearly distinguish between abuse, dependence, remission, or other clinical features.
Does an ICD-10 code determine what treatment someone receives?
No. ICD-10 codes primarily support diagnosis, documentation, billing, and insurance reimbursement. Treatment decisions are based on a comprehensive clinical assessment that considers symptom severity, substance use history, co-occurring conditions, medical needs, and each person’s individual recovery goals.
Can someone have both a stimulant use disorder code and a cocaine use disorder code?
Yes. If an individual uses cocaine along with another stimulant, such as methamphetamine or prescription amphetamines, providers may assign both F14 and F15 codes to accurately document the separate substance use disorders and guide comprehensive treatment planning.
How does remission status affect stimulant use disorder coding?
ICD-10 includes specific remission codes, such as F15.11 or F15.21, to indicate that stimulant abuse or dependence is no longer active. Documenting remission distinguishes past substance use disorders from current, active diagnoses and supports accurate clinical records.
Where can families get help understanding a stimulant use disorder diagnosis?
The best first step is speaking directly with the diagnosing healthcare provider, who can explain the diagnosis and treatment recommendations. Addiction treatment centers, mental health professionals, and family education programs can also provide guidance, resources, and ongoing support throughout recovery.
