ICD-10 Codes for Alcohol Use Disorder: Coding & Billing Guide

Patient often says they drink much but that statement alone does not tell the billing team which diagnosis belongs on the claim. Documentation must clearly show the diagnosis that the patient has and the treatment that the provider is giving. Then will the billing team know which diagnosis to use.

ICD‑10 codes for Alcohol Use Disorder rely on details such as severity, remission, intoxication, withdrawal and alcohol‑induced conditions. When those details are missing the claim may face questions about necessity, denial, payment delay or documentation concerns.

If you are reviewing other diagnoses as well, our ICD-10 coding resources can help your team connect clinical documentation with accurate diagnosis coding.

What Are the ICD-10 Codes for Alcohol Use Disorder?

The right code really depends on how you document the patient’s condition. I think when you have an AUD diagnosis the right code is guided by the patient’s condition. The first details you should look at are severity and remission status

The American Psychiatric Association maps mild AUD to F10.10, while moderate and severe AUD map to F10.20. When remission is documented, the corresponding codes are F10.11 and F10.21.

The words can seem confusing at first. DSM-5-TR talks about Alcohol Use Disorder. Has different levels of severity. ICD-10-CM uses the terms alcohol abuse and alcohol dependence inside the F10 group. The two systems are connected for use in the United States, for coding and billing.

Which ICD-10-CM Version Should You Use?

Start with the date of service, not the date you submit the claim.

FY2026 ICD-10-CM applies through September 30 2026. FY2027 ICD-10-CM applies from October 1 2026 through September 30 2027. CMS lists the FY2027 diagnosis files and guidelines as effective, for encounters during that period.

This matters when your team works older A/R, corrected claims, or documentation from an earlier encounter. Always verify the code against the version that applies to that date of service.

These codes can be appropriate when the documentation supports an unspecified diagnosis. They should not become the default simply because the note lacks details that could have been documented.

Alcohol Intoxication and Withdrawal Codes

Your patient’s presentation may require a more specific F10 code than uncomplicated AUD.

For example if the encounter involves intoxication or withdrawal write down the condition and any important signs or symptoms that stand out.

Here, your documentation makes the difference. If you document withdrawal with delirium, the coder has support for a more specific code. If you simply write “alcohol withdrawal,” the record may not support that level of detail.

Alcohol-Induced Disorders and Related Medical Conditions

Alcohol may also play a role in a patient’s psychiatric or medical condition. If you establish an alcohol-induced disorder, document the relationship clearly.

Examples within the F10 category include:

• F10.14 — Alcohol abuse with alcohol-induced mood disorder
• F10.180 — Alcohol abuse with alcohol-induced anxiety disorder
• F10.182 — Alcohol abuse with alcohol-induced sleep disorder
• F10.24 — Alcohol dependence with alcohol-induced mood disorder
• F10.280 — Alcohol dependence with alcohol-induced anxiety disorder
• F10.282 — Alcohol dependence with alcohol-induced sleep disorder
• F10.288 — Alcohol dependence with other alcohol-induced disorder
• F10.29 — Alcohol dependence with unspecified alcohol-induced disorder

“Alcohol use with anxiety” does not necessarily establish an alcohol-induced anxiety disorder. Your assessment should support the relationship before the coder assigns the more specific diagnosis.

The same principle applies when alcohol is associated with a medical condition. Alcoholic liver disease falls under K70.-, while alcohol-induced acute pancreatitis falls under K85.2-.

The FY2027 Official Guidelines clearly state that alcohol-induced acute pancreatitis must be coded using the K85.2- code and the relevant F10.2- code if alcohol dependence is recorded. The pancreatitis code must not be changed to F10.288.

If your practice frequently handles complex medical diagnoses, a medical coding guide can also give your billing team a useful reference point when reviewing related conditions.

How to Select the Right AUD Code

You do not need to write your note around the code. Instead, document the clinical picture clearly and let the coding process follow it.

1. State the diagnosis

Be clear about whether you diagnosed:

• Alcohol Use Disorder
• Alcohol abuse
• Alcohol dependence
• Alcohol intoxication
• Alcohol withdrawal
• An alcohol-induced psychiatric disorder
• An alcohol-related medical condition

2. Document severity when applicable

If you use DSM terminology, identify whether the disorder is mild, moderate, or severe.

The ICD-10-CM mapping is:

• Mild → F10.10
• Moderate → F10.20
• Severe → F10.20

The APA’s published coding information supports these mappings.

3. Document remission

If the patient is in remission, say so in the assessment when clinically appropriate.

• Mild AUD in remission → F10.11
• Moderate/severe AUD in remission → F10.21

Do not leave your billing team to infer remission from a negative alcohol screen.

4. Identify intoxication or withdrawal

If the condition is present explain what it is. Describe the important signs and symptoms. These might include things like confusion or changes, in how someone sees or hears things.

5. Review related conditions

If you are dealing with alcoholic liver disease or alcohol-induced pancreatitis or any other medical problem caused by alcohol be sure the diagnosis is written down on its own and given the code as told by the list of codes. Make sure each condition is listed separately and coded correctly. Always follow the instructions given in the list of codes.

What Should You Document for Cleaner Claims?

A strong clinical note does more than support the diagnosis. It gives your coding team enough information to submit the service without repeatedly sending queries back to you.

Consider documenting:

• The alcohol-related diagnosis
• Severity, when applicable
• Remission status
• Current symptoms
• Intoxication or withdrawal
• Relevant psychiatric manifestations
• Alcohol-related medical complications
• Assessment and treatment plan
• Services provided
• Clinical reasoning supporting the diagnosis

Compare these examples:

The goal is not to add unnecessary detail to every note. It is to document the details that actually affect diagnosis selection and the service you provided.

CPT and HCPCS Codes Related to Alcohol Use Disorder

Your ICD-10-CM code explains why you treated the patient. The CPT or HCPCS code explains what service you performed.

Some services that may apply to alcohol-use assessment or treatment include:

These codes do not automatically become payable because you documented AUD. The service, time, provider qualifications, place of service, documentation, medical necessity, and payer rules still need to support the claim.

That distinction becomes especially useful when your team reviews CPT coding alongside the diagnosis.

Blood Alcohol Levels Do Not Diagnose AUD

A blood alcohol level can provide useful clinical information, but it does not automatically establish Alcohol Use Disorder.

ICD-10-CM includes Y90.-, Evidence of alcohol involvement determined by blood alcohol level. Under the FY2027 Official Guidelines, a Y90 code may be assigned when the blood alcohol level is documented and the provider has documented a condition that falls under F10.

So think of the two pieces separately:

Blood alcohol level: evidence of alcohol involvement.

F10 diagnosis: the documented alcohol-related disorder.

A positive test does not allow a coder to independently diagnose dependence. Likewise, a negative test does not establish remission.

Outpatient vs. Inpatient Uncertain Diagnoses

The setting matters when you document an uncertain diagnosis.

For an outpatient encounter, terms such as “rule out,” “probable,” “suspected,” or “working diagnosis” do not support coding the condition as confirmed. The coder reports the highest level of certainty supported by the documentation.

For example, if you write “rule out Alcohol Use Disorder,” the billing team should not automatically report F10.20 as a confirmed diagnosis.

Inpatient discharge coding has rules for diagnoses that are not certain. This difference is important especially when the same medical terms show up in both hospital records and outpatient records.

Common AUD Coding Mistakes to Avoid

Using F10.90 when a specific diagnosis is documented

If you have clearly diagnosed mild, moderate, or severe AUD, an unspecified alcohol-use code may not accurately represent your assessment.

Letting laboratory results determine the diagnosis

Your lab findings can support your clinical assessment, but they should not replace it.

Leaving remission unclear

If remission affects your assessment and treatment, document it. Otherwise, the coding team may have to query the record.

Writing “alcohol withdrawal” without the relevant details

When clinically present, document whether the patient has delirium, perceptual disturbance, or uncomplicated withdrawal.

Choosing CPT from the diagnosis

F10.20 does not determine whether you performed 90834, 90837, 90791, or another service. Your documentation of the actual encounter determines the CPT/HCPCS selection.

Adding modifiers just to avoid a denial

A modifier should describe a legitimate circumstance of the service. Do not add one simply because a payer edit appears on a previous claim.

Frequently Asked Questions

What is the ICD-10 code for Alcohol Use Disorder?

There is no single code for every AUD diagnosis. Mild AUD generally maps to F10.10, while moderate and severe AUD generally map to F10.20. Remission changes the code to F10.11 or F10.21, depending on the documented category.

What is the ICD-10 code for mild Alcohol Use Disorder?

F10.10 — Alcohol abuse, uncomplicated is the commonly used ICD-10-CM mapping for mild AUD.

What is the ICD-10 code for moderate or severe Alcohol Use Disorder?

Moderate and severe AUD generally map to F10.20 — Alcohol dependence, uncomplicated, when no intoxication, withdrawal, or other qualifying condition changes the code selection.

What is the ICD-10 code for AUD in remission?

Mild AUD in remission generally maps to F10.11. Moderate or severe AUD in remission generally maps to F10.21.

Can a blood alcohol test establish AUD?

No. A blood alcohol level can document alcohol involvement, but it does not independently establish AUD. The provider’s documented diagnosis remains essential.

Does F10.20 automatically support psychotherapy billing?

No. F10.20 identifies the diagnosis. The CPT code still must match the service you performed and meet documentation, medical necessity, payer, and other billing requirements.

Which ICD-10-CM version applies after October 1, 2026?

FY2027 ICD-10-CM applies to patient encounters from October 1, 2026, through September 30, 2027.

Final Takeaway

The ICD-10 codes for Alcohol Use Disorder become much easier to select when your assessment clearly states the diagnosis, severity, remission status, and any intoxication, withdrawal, or related condition.

For your billing team, that clarity matters. It helps them connect the diagnosis to the right CPT or HCPCS code, verify medical necessity, and submit a claim that accurately reflects the care you provided.

Document the clinical picture. Let the coding team verify the code. And when the record does not support a more specific diagnosis, do not let assumptions fill the gap.
