ICD-10 Code D13.4 – Benign neoplasm of liver (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D13.4 – Benign neoplasm of liver
What it is
D13.4 identifies a noncancerous growth in the liver. It is used when documentation confirms a benign hepatic neoplasm rather than a malignant tumor or secondary cancer.
Clinical signs
Clinical features vary; refer to documentation. Many cases are found incidentally on imaging, while others may be described as a liver mass, focal lesion, or benign tumor with no evidence of invasion.
When to use this code
Use D13.4 when the record states a benign neoplasm of the liver, such as a confirmed nonmalignant hepatic tumor. Apply it when pathology, imaging, or specialist documentation supports a benign diagnosis. If the provider documents uncertainty, check documentation before coding.
Do not use for
Do not use this code for malignant liver tumors, metastatic disease, or unspecified liver masses without a benign diagnosis. If the chart only says “liver lesion” or “mass,” check documentation.
Coding tip
Code D13.4 only when the provider clearly documents benign liver neoplasm; otherwise, query for specificity.
