About K76.5

K76.5 is the ICD-10-CM diagnosis code for hepatic veno-occlusive disease. 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 (other diseases of liver), K76.5 is specifically for hepatic veno-occlusive disease. Related codes cover 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), portal hypertension (K76.6), hepatorenal syndrome (K76.7), other specified diseases of liver (K76.8) and 1 more.

Don't report K76.5 together with the conditions in its Excludes1 note: Budd-Chiari syndrome (I82.0).

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.

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 573.8 (other specified disorders of liver).
