Alcohol Use Disorder Guidelines

Definition and Classification

• Alcohol use disorder is classified as a spectrum with mild, moderate, and severe classifications by the American Psychiatric Association's DSM-5, which can be mapped to ICD-10 codes, with severe alcohol use disorder generally mapping to F10.2 (Dependence syndrome) 1, 2
• The ICD-10 classification system codes alcohol-related disorders primarily under the F10 category, including F10.1 - Harmful use of alcohol, F10.2 - Alcohol dependence syndrome, F10.0 - Acute alcohol intoxication, and F10.3-F10.9 - Various alcohol-induced conditions 2

Diagnosis and Screening

• The AUDIT (Alcohol Use Disorders Identification Test) is the gold standard screening tool for identifying alcohol use disorders 1
• The CAGE questionnaire is a simpler screening tool, but has lower sensitivity for hazardous drinking and should be used in conjunction with other screening tools 2
• Positive screenings should lead to appropriate coding and intervention, using ICD-10 codes to support documentation of alcohol-related behaviors and consequences 2

Coding and Remission Criteria

• The World Health Organization recommends using the F10.21 code to indicate alcohol dependence in remission, rather than F10.10 (harmful use) or Z codes (history of) 1
• For a patient to be considered in remission from alcohol use disorder, they must have previously met the criteria for alcohol dependence but currently do not meet the criteria except possibly for craving, and no longer exhibit the characteristic withdrawal syndrome, tolerance to alcohol, failure to fulfill major role obligations due to alcohol, or use alcohol in physically hazardous situations 1
• F10.1 - Harmful use of alcohol is the most appropriate code for patients who drink despite recurrent social, interpersonal, and legal problems as a result of alcohol use 2
• F10.2 - Alcohol dependence syndrome should be used when physiological dependence is present with significant problems in the person's life 2

Documentation and Treatment

• Clinicians should clearly document the patient's previous dependence, duration of abstinence or controlled drinking, ongoing symptoms, and relapse prevention strategies when coding for alcohol use disorder in remission 1
• Accurate coding has important implications for treatment planning, insurance coverage, epidemiological data collection, and patient stigmatization 1
• The American Academy of Family Physicians and other medical organizations recommend using current classification systems and avoiding outdated terminology to ensure accurate coding and effective treatment 2
