K70.41Alcoholic hepatic failure with coma

K70.41 is the ICD-10-CM diagnosis code for alcoholic hepatic failure with coma. It belongs to category K70 (alcoholic liver disease), block K70-K77 (diseases of liver) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within K70.4 (alcoholic hepatic failure), K70.41 is specifically for alcoholic hepatic failure with coma. Related codes cover without coma (K70.40).

Use an additional code to identify: alcohol abuse and dependence (F10.-).

As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 432 (Cirrhosis and Alcoholic Hepatitis with MCC, relative weight 1.9828), DRG 433 (Cirrhosis and Alcoholic Hepatitis with CC, relative weight 1.0397) and DRG 434 (Cirrhosis and Alcoholic Hepatitis without CC/MCC, relative weight 0.6413), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 571.3 (alcoholic liver damage, unspecified) and 572.2 (hepatic encephalopathy).
