Fibrosis and cirrhosis of liver (K74) ICD-10-CM
The K74 code range covers fibrosis and cirrhosis of liver with 13 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K74 range.
Clonorchiasis
Infection of the biliary passages with CLONORCHIS SINENSIS, also called Opisthorchis sinensis. It may lead to inflammation of the biliary tract, proliferation of biliary epithelium, progressive portal fibrosis, and sometimes bile duct carcinoma. Extension to the liver may lead to fatty changes and cirrhosis. (From Dorland, 27th ed)
Clonorchis sinensis
A species of trematode flukes of the family Opisthorchidae. Many authorities consider this genus belonging to Opisthorchis. It is common in China and other Asiatic countries. Snails and fish are the intermediate hosts.
Opisthorchiasis
Infection with flukes of the genus Opisthorchis.
About the K74 Code Range
The ICD-10 code K74 covers conditions related to fibrosis and cirrhosis of the liver, including a range of liver scarring diseases that impair normal liver function. These codes are used to classify various stages and causes of liver fibrosis and cirrhosis in medical records.
This section includes codes for hepatic fibrosis (K74.0), which describes scarring of the liver tissue, with subcategories like early fibrosis (K74.01) and advanced fibrosis (K74.02). It also covers hepatic sclerosis (K74.1) and combinations of fibrosis with sclerosis (K74.2). For cirrhosis related to bile duct damage, codes for primary biliary cirrhosis (K74.3), also known as autoimmune liver disease or primary biliary cholangitis, and secondary biliary cirrhosis (K74.4) are included. Biliary cirrhosis unspecified is coded under K74.5. The section further includes other and unspecified cirrhosis types (K74.6), with distinctions for unspecified (K74.60) and other specific cirrhosis forms (K74.69), covering conditions such as Laennec's cirrhosis, cryptogenic cirrhosis, and cirrhosis secondary to infections or metabolic disorders. These codes assist coders in accurately documenting liver scarring disorders, helping to identify conditions like non-alcoholic fatty liver disease, chronic hepatitis, and various autoimmune or parasitic etiologies.
