ICD 10 Code for Alcohol Use Disorder: Diagnosis, Severity, Coding Guidelines & Billing

Accurate diagnosis coding is essential when documenting and billing for alcohol-related conditions. However, the ICD 10 code for Alcohol Use Disorder is not always a single code. The appropriate ICD-10-CM code depends on the provider’s documented diagnosis, the pattern of alcohol use, whether intoxication or withdrawal is present, and whether an alcohol-induced disorder has been identified.

Even in behavioral health/substance use disorder treatment, the correct alcohol use disorder coding can set the stage for medical necessity, drive claim submission, assist with reimbursement and, if all else fails, provides a better patient record, year after year. Coding teams shouldn’t treat the phrase “alcohol use disorder” as an instruction to code any alcohol use disorder.

Get to know the common alcohol use disorder ICD 10 codes, severity-related coding considerations, documentation, billing considerations, and common coding mistakes that can impact your claim.

What Is the ICD 10 Code for Alcohol Use Disorder?

Not all ICD-10-CM codes in the F10 category are suitable for all patients diagnosed with AUD. The F10 section includes codes for alcohol abuse, alcohol dependence, and alcohol use, unspecified. Subcategories indicate intoxication, withdrawal, remission, and alcohol-related health conditions.

Such as F10.20 – Alcohol dependence, uncomplicated, F10.10 – Alcohol abuse, uncomplicated, and F10.90 – Alcohol use, unspecified, uncomplicated. Provider documentation supports an alcohol use disorder diagnosis code and complies with current ICD-10-CM guidelines.

The distinction is important because ICD-10-CM coding does not simply convert the clinical phrase “alcohol use disorder” into one universal F10 code. The documented pattern and associated clinical circumstances determine the appropriate code.

For the most current diagnosis code information, coding teams should verify the applicable official ICD-10-CM code set and current coding guidelines before assigning a code.

Common ICD 10 Codes for Alcohol Use Disorder

The following are commonly encountered codes within the F10 category:

The F10 category contains additional codes for intoxication delirium, withdrawal delirium, withdrawal with perceptual disturbance, psychotic disorders with hallucinations, and other alcohol-induced conditions.

Alcohol Use Disorder Codes by Severity and Clinical Pattern

If documentation states ‘mild’, ‘moderate’, and ‘severe’, providers have not added any additional information to distinguish this as three separate F10 codes. Coding team should not automatically interpret this as mild, moderate, and severe.

According to the FY 2026 instructions, “Assign [the individual] to the appropriate codes for mild substance-using-in-remission…or to the appropriate codes for moderate or severe substance dependence in remission. Provider documentation and clinical judgment are required for remission coding.

The documentation should therefore be reviewed carefully before selecting an alcohol use disorder ICD-10-CM code.

Clinically, alcohol use disorder can be classified as mild, moderate, or severe based on the number of diagnostic criteria met, but the clinical severity classification should not be treated as a direct one-to-one mapping to a specific ICD-10-CM code. For additional clinical background, see this resource on understanding alcohol use disorder and its severity.

Mild Alcohol Use Disorder

If the provider documents a mild alcohol use disorder, it should be coded to the corresponding ICD-10-CM code that corresponds to the provider’s documented pattern of use. Coders should not automatically translate the severity statement to a code without reviewing the guidelines.

Moderate or Severe Alcohol Use Disorder

Moderate or severe AUD may correspond to the dependence classification when supported by provider documentation and the applicable ICD-10-CM guidelines. The record should clearly establish the diagnosis rather than relying on assumptions based on alcohol consumption alone.

Alcohol Use Disorder in Remission

Remission coding requires provider documentation. FY2026 guidelines specifically state that codes describing remission for F10-F19 categories are assigned on the basis of provider documentation unless the classification provides otherwise.

Alcohol Abuse vs. Alcohol Dependence vs. Alcohol Use, Unspecified

One of the most important parts of alcohol use disorder diagnosis coding is understanding the difference between the F10 classifications.

Alcohol abuse codes are found under F10.1-, while alcohol dependence codes are found under F10.2-. Alcohol use, unspecified is classified under F10.9-. Each category also contains additional codes for intoxication, withdrawal, and alcohol-induced disorders.

Consider the following hierarchy when all three elements – use, abuse, and dependence – of the same substance are documented: in the event that both use and abuse are documented, assign abuse; in the event that abuse and dependence are documented, assign dependence; in the event that use, abuse, and dependence are documented, assign dependence.

This prevents multiple overlapping F10 codes from being assigned simply because several terms appear in the medical record.

Alcohol Use Disorder With Intoxication or Withdrawal

Encounters involving alcohol can be categorized as related to intoxication or withdrawal that would necessitate more specific coding.

For example, F10.220 is alcohol dependence with intoxication, uncomplicated. While F10.230 is alcohol dependence with withdrawal, uncomplicated. There are also codes for intoxication delirium, withdrawal delirium, and withdrawal with perceptual disturbance.

The documentation should establish the clinical condition being treated. Coders should not assign an intoxication or withdrawal code simply because alcohol use is mentioned in the record.

Alcohol-Induced Disorders and Related Codes

Alcohol can also be associated with other documented conditions. F10 Codes for alcohol-induced Mood disorders, Psychotic disorders, anxiety disorders, sleep disorders, and other alcohol-induced disorders.

F10.280 – Alcohol dependence with alcohol-induced anxiety disorder F10.282 – Alcohol dependence with alcohol-induced sleep disorder. Don’t miss these: Like this: For instance, F10.280 means alcohol dependence with an alcohol-induced anxiety disorder.

Before choosing an alcohol-induced disorder code, the coder should examine the provider’s documentation and refer to the ICD-10-CM tabular instructions.

How to Choose the Correct Alcohol Use Disorder Diagnosis Code

Selecting the correct alcohol ICD 10 code requires a structured review of the medical record.

Review the Provider’s Diagnosis

Begin with the provider’s diagnosis and documentation of the diagnosis. Never diagnose alcohol use disorder based on a screening result, signs or symptoms, laboratory findings, or patient-reported alcohol use.

Identify the Documented Pattern of Use

Check if alcohol abuse, alcohol dependence, unspecified alcohol use, or any other alcohol-related diagnosis has been written down by the doctor.

Check for Intoxication or Withdrawal

If intoxication or withdrawal has been recorded, determine if another relevant F10 category is more suitable. Investigate the subcategories for uncomplicated intoxication, delirium, perceptual disturbance, and unspecified manifestation.

Review Alcohol-Induced Conditions

Determine if the provider listed an alcohol-related emotion, psychosis, anxiety, sleep, or other disorder. Such diagnoses may need a more detailed code.

Verify Current Coding Guidelines

ICD-10-CM codes and guidelines are updated annually. Coding teams should verify the applicable code set for the date of service before claims are submitted.

Alcohol Use Disorder Documentation Requirements

Accurate alcohol use disorder documentation gives coders the information needed to select an appropriate diagnosis code.

Depending on the encounter, documentation may include:

• Provider-documented diagnosis
• Pattern and severity of alcohol use when clinically relevant
• Intoxication or withdrawal status
• Associated medical or behavioral conditions
• Alcohol-induced disorders when diagnosed
• Remission status when documented
• Assessment and treatment plan
• Medical necessity for the service
• Relevant clinical findings

Coders should not add specificity that the provider has not documented. Clear documentation also helps support claims during payer reviews or medical necessity assessments.

ICD-10-CM vs. CPT Codes for Alcohol Use Disorder

CPT and ICD-10-CM codes serve different purposes on a claim.

ICD-10-CM codes identify the patient’s diagnosis or condition. CPT codes describe the healthcare service performed by the provider.

For substance use treatment, the diagnosis code can help explain the clinical reason for a service, while the CPT code identifies the actual service provided. The codes should be supported by the medical record and applicable payer requirements.

Practices that need assistance with substance abuse coding and billing services may use professional medical coding support to review diagnosis and procedure code selection before claims are submitted.

Alcohol Use Disorder Billing and Claims Workflow

The process of coding for alcohol use disorder may be 100% accurate; however, this is just one piece of successful alcohol use disorder billing. An effective workflow will include each step from eligibility through reimbursement.

Verify Insurance Benefits

Verify eligibility, behavioral health benefits, limitations of coverage, prior authorization required, deductibles and any other pertinent plan requirements prior to provision of services whenever feasible.

Review Documentation and Codes

Review the provider’s documentation and verify that the diagnosis and procedure codes accurately represent the encounter.

Submit Clean Claims

Claims should contain accurate patient, provider, diagnosis, procedure, and payer information. Pre-submission claim review can help identify missing or inconsistent information.

Monitor Claim Adjudication

Track submitted claims and review payer responses promptly. Claims that are rejected or denied must be corrected or appealed according to the payer’s specifications and timelines.

Follow Up on Unpaid Claims

Track if the unpaid or underpaid claims are being monitored as part of the accounts receivables process. Follow up in a timely manner so they do not get aged.

Common Alcohol Use Disorder Coding and Billing Errors

Using an Unspecified Code Automatically

F10.90 may be appropriate in some circumstances, but it should not automatically be used when the provider has documented a more specific alcohol-related diagnosis.

Confusing Abuse and Dependence Codes

F10.1- and F10.2- represent different classifications. Coding teams should follow provider documentation and the official hierarchy when multiple terms are documented.

Coding From Symptoms Instead of the Diagnosis

Alcohol consumption, intoxication symptoms, or withdrawal symptoms do not automatically establish the final diagnosis. The code should be supported by provider documentation.

Missing Intoxication or Withdrawal Specificity

When a record indicates intoxication, withdrawal, delirium, or perceptual disturbance, the coder is required to assign the appropriate code in the F10 subcategory of the 7th character, as opposed to the default uncomplicated code.

Ignoring Remission Documentation

Remission codes should be assigned when supported by the provider’s documentation and applicable guidelines.

Diagnosis and Procedure Codes Do Not Align

The diagnosis must reflect the clinical necessity for the service being billed. When the diagnosis does not correspond with the billing code, questions, edits or denials may occur.

How Accurate Coding Supports Alcohol Use Disorder Reimbursement

Accurate alcohol use disorder claims depend on more than selecting an F10 code. The claim should connect the provider’s documented diagnosis with the service performed and the payer’s requirements.

A consistent coding and billing process can help practices:

• Reduce avoidable coding errors
• Support medical necessity
• Submit cleaner claims
• Identify documentation gaps
• Reduce unnecessary rework
• Track denials more effectively
• Improve reimbursement follow-up

Coding for behavioral health/substance use treatment providers should be integrated into the overall revenue cycle, not relegated as an administrative or miscellaneous function.

When Practices May Need Alcohol Use Disorder Billing Support

Substance use treatment practices often manage detailed documentation, behavioral health benefits, authorization requirements, diagnosis coding, claims, and payer-specific rules. As patient volume increases, handling each part internally can become difficult.

Physician-led practices may also consider physician billing services when they need support with coding, claims management, eligibility verification, and denial follow-up.

Practices might seek alcohol use disorder medical billing services, alcohol use disorder coding and billing services or substance abuse medical billing services for help with the coding, pre-authorization/eligibility verification, claim submission, denial management, payment posting and A/R follow-up.

Behavioral health services that Wisconsin providers give Similarly, mental health billing services may also be used when treating alcohol use disorder alongside other psychiatric/behavioral health service. Wisconsin Medical Billing specifically provides billing support for mental health practices, including coding, claims submission, authorization management, denial management, and payment posting.

Final Takeaway

The ICD 10 Code for Alcohol Use Disorder can be classified based on the diagnosing provider and the context of the situation. The F10 category encompasses alcohol abuse, alcohol dependence, unspecified alcohol use, intoxication, withdrawal, remission and alcohol-induced disorders.

Providers and coders should refrain from running an unspecified code or choosing a diagnosis based solely on symptoms. Vetting the provider’s documentation and the current ICD-10-CM guidelines, as well as related diagnoses and payer criteria, can facilitate claim accuracy.

Frequently Asked Questions

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

There is no single ICD-10-CM code for every Alcohol Use Disorder diagnosis. Common F10 codes include F10.10 for alcohol abuse, uncomplicated; F10.20 for alcohol dependence, uncomplicated; and F10.90 for alcohol use, unspecified, uncomplicated. More specific F10 codes apply when intoxication, withdrawal, remission, or alcohol-induced disorders are documented.

What is F10.20?

F10.20 represents alcohol dependence, uncomplicated. The code should be assigned when the provider’s documentation supports alcohol dependence without a separately specified intoxication, withdrawal, or alcohol-induced disorder represented by another F10 code.

What is F10.10?

F10.10 represents alcohol abuse, uncomplicated. Coding should follow the provider’s documented diagnosis and current ICD-10-CM guidelines.

What is the ICD-10 code for alcohol dependence in remission?

F10.21 represents alcohol dependence, in remission. Remission coding should be supported by provider documentation and the applicable ICD-10-CM guidelines.

What is the ICD-10 code for alcohol use, unspecified?

F10.90 represents alcohol use, unspecified, uncomplicated. Other F10.9- codes identify unspecified alcohol use with intoxication, withdrawal, remission, or alcohol-induced disorders.

What is the ICD-10 code for alcohol withdrawal?

There is not one universal alcohol withdrawal code. The applicable F10 code depends on the documented pattern of alcohol use and whether withdrawal is uncomplicated, involves delirium, includes perceptual disturbance, or is otherwise unspecified. For example, F10.230 represents alcohol dependence with withdrawal, uncomplicated.

Can alcohol use disorder be coded with another mental health condition?

Yes, when the provider documents an applicable alcohol-induced or coexisting condition and the ICD-10-CM classification supports reporting it. The specific coding depends on the documented relationship and applicable instructions.

Does an Alcohol Use Disorder diagnosis guarantee reimbursement?

No. An ICD-10-CM diagnosis does not guarantee payment. Reimbursement depends on medical necessity, documentation, coverage, authorization, payer requirements, correct coding, and the service billed.

How can practices reduce alcohol use disorder billing errors?

Practices can also reduce preventable errors by a maintaining clear documentation, reviewing a correct F10 classification, checking for the intoxication or withdrawal, verifying remission status, submitting a clean claim, monitoring the denials, and following the payer requirements.
