About coding liver fibrosis
The ICD-10-CM code for liver fibrosis is K74.00 (Hepatic fibrosis, unspecified). The official index lists 9 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K74.00.
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.
