ICD-10 Code C22.7 – Other specified carcinomas of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C22.7 – Other specified carcinomas of liver
What it is
This code identifies a malignant carcinoma involving the liver that does not fit a more specific liver cancer code. Use it when the record clearly states another specified carcinoma of the liver.
Clinical signs
Clinical features vary; refer to documentation. Patients may have imaging or pathology findings consistent with liver carcinoma, but the exact tumor type is not otherwise classified in the record.
When to use this code
Use C22.7 when the provider documents a specified carcinoma of the liver and no more precise ICD-10-CM liver cancer code applies. It is appropriate when pathology, imaging, or the final diagnosis names a carcinoma subtype that is not otherwise indexed. Check documentation if the note is vague or only says “liver cancer.”
Do not use for
Do not use this code for hepatocellular carcinoma, intrahepatic bile duct cancer, or secondary malignant neoplasm of the liver. If the documentation does not specify a carcinoma type, check documentation.
Coding tip
Match the exact wording in the final diagnosis and verify that the carcinoma is primary to the liver before assigning C22.7.
