Other inflammatory liver diseases (K75) ICD-10-CM
The K75 code range covers other inflammatory liver diseases with 10 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the K75 Code Range
The ICD-10 code section K75 covers a variety of other inflammatory liver diseases, including specific conditions like liver abscess, portal vein phlebitis, autoimmune hepatitis, and nonalcoholic steatohepatitis (NASH). These codes help identify and classify non-infectious and infectious inflammatory disorders of the liver.
This group of codes is used to document conditions such as liver abscess (K75.0), which is sometimes called bacterial liver abscess or pyogenic hepatic abscess, and phlebitis of the portal vein (K75.1), also known as portal vein thrombosis. It also includes nonspecific reactive hepatitis (K75.2) and granulomatous hepatitis (K75.3), which can be related to infections like schistosomiasis. The section specifies autoimmune conditions like autoimmune hepatitis (K75.4), which may be referred to as autoimmune liver disease or lupus hepatitis. Additionally, nonalcoholic steatohepatitis (NASH, K75.81) is included, often described as non-alcoholic fatty liver disease. Other less common inflammatory liver diseases fall under K75.8 and K75.89, while unspecified inflammatory liver conditions are coded as K75.9. Understanding these codes assists in accurate diagnosis and treatment documentation for inflammatory liver diseases.
