About K76.6

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

Use an additional code for any associated complications, such as: portal hypertensive gastropathy (K31.89).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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 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 572.3 (portal hypertension).
