ICD-10-CM Codes›K00–K95›K70-K77›K70

- Chronic Condition
K70.41 is a billable ICD-10-CM diagnosis code for alcoholic hepatic failure with coma. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 432 through 434. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 6 closely related codes. The code is restricted by the Medicare Code Editor to adult patients (age 15 through 124). Coders also document this condition as hepatic coma due to alcoholic liver failure. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Alcohol-related disorders, Coma; stupor; and brain damage, and Hepatic failure.
For Medicare Advantage risk adjustment, K70.41 maps to CMS-HCC Category 63 (Chronic Liver Failure/End-Stage Liver Disorders) under the V28 model, adding a risk factor of about 0.962 for a community, non-dual, aged beneficiary in payment year 2027.

Alcohol Use Disorder (AUD)
For most adults, moderate alcohol use is probably not harmful. Your risk of developing an alcohol use disorder (AUD) depends on how much, how often, and how quickly you drink alcohol. Alcohol misuse means that drinking causes distress and harm. Over time alcohol misuse can increase your risk of AUD.
