Fibrosis and cirrhosis of liver (K74) ICD-10-CM
The K74 code range covers fibrosis and cirrhosis of liver with 14 ICD-10-CM diagnosis codes. 11 of them are billable and valid for claim submission in fiscal year 2027, 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.
Advanced Liver Fibrosis
Septal or bridging fibrosis that results in the disruption of normal blood flow and liver function, and extends across hepatic lobules with significant porto-portal or porto-central bridging. Progression may lead to the formation of nodules that distort the liver architecture, which is termed cirrhosis.
Cirrhosis
A disorder characterized by replacement of the liver parenchyma with fibrous tissue and regenerative nodules. It is usually caused by alcoholism, hepatitis B, and hepatitis C. Complications include the development of ascites, esophageal varices, bleeding, and hepatic encephalopathy.
Hepatic Sclerosis
A thickening of the liver parenchyma. Hepatic sclerosis, fibrosis and cirrhosis may exist along a continuum.
Liver Cirrhosis, Biliary
FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cholangitis involves the destruction of small intra-hepatic bile ducts and decreased bile secretion. Secondary biliary cholangitis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.
Liver Fibrosis
A condition in which the liver parenchyma is replaced by fibrous tissue. It may progress to cirrhosis of the liver.
Primary Biliary Cholangitis
An autoimmune inflammatory disorder characterized by destruction of the small intrahepatic bile ducts. It affects predominantly females and it may lead to cirrhosis and liver failure. Patients have antimitochondrial and antinuclear antibodies in the peripheral blood.
Secondary Biliary Cirrhosis
Biliary cirrhosis due to obstruction of the extrahepatic ducts.
About the K74 Code Range
Liver fibrosis, liver sclerosis, and cirrhosis are grouped in this category of liver diseases. Hepatic means liver.
K74.0 covers liver fibrosis, with subdivisions for early, moderate, advanced, and unspecified fibrosis. K74.1 identifies liver sclerosis alone, while K74.2 identifies fibrosis with sclerosis. Biliary cirrhosis is divided into primary K74.3, secondary K74.4, and unspecified K74.5. K74.6 covers other and unspecified cirrhosis of the liver.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added K74.0A.
