Hepatic Lesion

Is the Hepatic Lesion ICD code billable? 

The most accurate ICD-10-CM code for Hepatic Lesion or liver lesion is K76.89: Other specified diseases of the liver. This billable code is widely used by healthcare professionals for diagnosis documentation, communication, and billing, especially when a liver lesion does not fall under a more specific category, such as malignancy or benign growth.

However, depending on the type of liver lesion, the ICD-10-CM coding can vary:

• K76.89 - Other specified diseases of the liver: Used for Hepatic Lesions not classified elsewhere, including cysts, nodules, or tumors. This is the most common default code for unspecified liver lesions.
• D13.4 – Benign neoplasm of liver, not elsewhere classified: Used for benign liver lesions such as focal nodular hyperplasia (FNH) or hepatic adenomas.
• D13.9 – Benign neoplasm of unspecified digestive organ: Used when benign liver tumors or cystic disease have unspecified characteristics.
• C22.0 – Liver cell carcinoma: Used for primary malignant liver tumors such as hepatocellular carcinoma (HCC).
• K75.0 – Abscess of liver: Used for infectious liver lesions caused by bacterial or parasitic infections.
• K76.3 – Infarction of liver: Used when liver tissue dies due to blood flow obstruction, such as hepatic vein thrombosis.
• D18.0 – Hemangioma of liver: Used for benign vascular liver lesions, typically incidental findings.
• K76.8 – Other specified diseases of liver: Used for other liver conditions not classified elsewhere.
• K76.82 – Hepatic encephalopathy: Used for neurological symptoms caused by chronic or advanced liver disease.
• R93.2 – Abnormal findings on imaging of liver and biliary tract: Used for imaging abnormalities that suggest a lesion before a confirmed diagnosis.

Clinical information

• Hepatic Lesions, also called liver lesions, refer to abnormal tissue growths in the liver. These may result from various conditions such as viral hepatitis, toxic liver disease, or amyloid degeneration of the liver. Lesions are broadly categorized as either benign liver lesions (e.g., focal nodular hyperplasia, hemangiomas) or malignant tumors like hepatocellular carcinoma.
• Common causes of Hepatic Lesions include chronic viral hepatitis (B or C), cirrhosis, long-term use of anabolic steroids or oral contraceptives, genetic mutations, and exposure to liver toxins.
• Symptoms of liver lesions, especially if malignant, may involve fatigue, abdominal pain, unexplained weight changes, loss of appetite, fever, and nausea. In some cases, liver lesions may remain asymptomatic and are detected only through imaging studies.
• Diagnostic evaluation often includes blood tests for liver function and tumor markers, imaging tests (ultrasound, CT, or MRI), and liver biopsy when malignancy or atypical features are suspected.
• Treatment depends on the underlying cause and nature of the lesion. For malignant tumors, treatment may involve surgical resection, liver transplantation, chemotherapy, embolization, ablation, or targeted therapy. In contrast, benign lesions may only require monitoring unless symptomatic.
