ICD Code C22.7

ICD code C22.7 is other specified carcinomas of the liver, referring to liver cancers that are not classified under more common types like hepatocellular carcinoma or intrahepatic bile duct carcinoma.

1. Presence of a malignant neoplasm originating in the liver that does not meet criteria for hepatocellular carcinoma or intrahepatic cholangiocarcinoma

2. Histopathological confirmation of a carcinoma subtype in the liver that is specifically classified as “other specified” by the pathologist

3. Imaging studies (CT, MRI, or ultrasound) demonstrating a primary liver mass with features inconsistent with the most common liver carcinoma types

4. Exclusion of metastatic carcinoma to the liver from another primary site

5. Clinical presentation may include right upper quadrant abdominal pain, unexplained weight loss, jaundice, hepatomegaly, or abnormal liver function tests

6. No evidence of cirrhosis or viral hepatitis as the sole underlying etiology for the liver lesion

7. Documentation in the medical record specifying the carcinoma subtype as “other specified” rather than “unspecified” or a more common liver carcinoma type
