About K76.82

K76.82 is the ICD-10-CM diagnosis code for hepatic encephalopathy. It belongs to category K76 (other diseases of liver), 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 K76.8 (other specified diseases of liver), K76.82 is specifically for hepatic encephalopathy. Related codes cover Hepatopulmonary syndrome (K76.81), intestinal failure-associated liver disease (K76.83) and other specified diseases of liver (K76.89).

Don't report K76.82 together with the conditions in its Excludes1 note: acute and subacute hepatic failure with coma (K72.01), alcoholic hepatic failure with coma (K70.41), chronic hepatic failure with coma (K72.11) and hepatic failure with coma (K72.91).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 441 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with MCC, relative weight 1.8219), DRG 442 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CC, relative weight 0.9602), DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2023, effective October 1, 2022.
