ICD-10 code for liver disorder

The ICD-10-CM code for liver disorder is K76.9 (Liver disease, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on K76.9.

Within K76, choose K76.9 (Liver disease, unspecified) only when documentation doesn't support a more specific option: fatty (change of) liver, not elsewhere classified (K76.0), chronic passive congestion of liver (K76.1), central hemorrhagic necrosis of liver (K76.2), infarction of liver (K76.3), Peliosis hepatis (K76.4), hepatic veno-occlusive disease (K76.5), portal hypertension (K76.6), hepatorenal syndrome (K76.7) and 1 more.

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) and DRG 443 (Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis without CC/MCC, relative weight 0.6885), 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.
