About K74.00

K74.00 is the ICD-10-CM diagnosis code for hepatic fibrosis, unspecified. It belongs to category K74 (fibrosis and cirrhosis 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 K74.0, choose K74.00 (unspecified) only when documentation doesn't support a more specific option: early fibrosis (K74.01), advanced fibrosis (K74.02) and moderate fibrosis (K74.0A).

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 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.

It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It was added in FY2021, effective October 1, 2020.
