Liver Lesions ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Liver Lesions?

Liver lesions are abnormal areas of tissue in the liver that can be caused by various conditions such as tumors, cysts, abscesses, or hemangiomas. Accurate coding of liver lesions is essential for medical documentation, billing, and research purposes. The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) provides specific codes to classify liver lesions based on their characteristics and underlying etiology. Here are six to ten commonly used ICD-10-CM codes for liver lesions, along with their clinical descriptions:

‍D13.9 - Benign neoplasm of unspecified digestive organ

This code is used for benign liver tumors or cysts with uncertain behavior or unspecified characteristics.

C22.0 - Liver cell carcinoma

It is assigned to primary malignant liver tumors that originate from hepatocytes. It includes hepatocellular carcinoma (HCC) and hepatoma.

D13.0 - Benign neoplasm of liver, not elsewhere classified

This code represents benign liver tumors, such as adenomas or focal nodular hyperplasia (FNH), which are non-cancerous growths.

K76.6 - Portal hypertension

This code indicates increased blood pressure in the portal vein system, often caused by liver cirrhosis or other liver diseases, leading to liver lesions like varices.

K76.7 - Hepatorenal syndrome

It is used for liver-associated kidney dysfunction characterized by reduced kidney function, typically occurring in advanced stages of liver disease.

K75.0 - Abscess of liver

This code is used for localized collections of pus within the liver, usually resulting from bacterial infections. It is associated with fever, abdominal pain, and liver enlargement.

K76.3 - Infarction of liver

This code is assigned to cases where a portion of liver tissue undergoes necrosis due to inadequate blood supply, often caused by a blood clot in the hepatic artery or portal vein.

D18.0 - Hemangioma of liver

This code represents benign liver lesions composed of clusters of blood vessels. Hemangiomas are usually asymptomatic and require monitoring rather than treatment.

K71.6 - Toxic liver disease with hepatic necrosis

This code is used for liver damage caused by exposure to toxic substances, leading to necrosis of liver cells. Examples include drug-induced liver injury or acute alcoholic hepatitis.

K76.8 - Other specified diseases of liver

This code covers a range of liver conditions not classified under the previously mentioned codes, such as liver fibrosis, granulomatous hepatitis, or hepatic lipidosis.

Which Liver Lesions ICD codes are Billable: 

D13.9 - Benign neoplasm of unspecified digestive organ

Yes. This code is billable as it represents benign liver tumors or cysts of unspecified characteristics requiring medical evaluation and management.

C22.0 - Liver cell carcinoma

Yes. This code is billable as it signifies primary malignant liver tumors, such as hepatocellular carcinoma (HCC), necessitating extensive medical interventions and ongoing care.

D13.0 - Benign neoplasm of liver, not elsewhere classified

Yes. This code is billable, representing specific benign liver tumors like adenomas or focal nodular hyperplasia (FNH) that may require medical surveillance or treatment.

K76.6 - Portal hypertension

No. This code is not billable as it represents a condition rather than a specific liver lesion. It indicates increased blood pressure in the portal vein system and is typically used for diagnostic or descriptive purposes.

K76.7 - Hepatorenal syndrome

No. This code is not billable as it represents a syndrome associated with liver disease rather than a distinct liver lesion. It is utilized for diagnostic or descriptive purposes.

K75.0 - Abscess of liver

Yes. This code is billable as it represents a localized collection of pus within the liver, requiring medical intervention, such as drainage or antibiotic treatment.

K76.3 - Infarction of liver

Yes. This code is billable as it indicates liver tissue necrosis due to inadequate blood supply, necessitating medical evaluation and treatment.

D18.0 - Hemangioma of liver

Yes. This code is billable as it represents benign liver lesions composed of blood vessels, which may require monitoring or intervention depending on the size or symptoms.

K71.6 - Toxic liver disease with hepatic necrosis

Yes. This code is billable as it represents liver damage caused by exposure to toxic substances, requiring medical management and monitoring.

K76.8 - Other specified diseases of the liver

Yes. This code is billable as it covers various specific liver conditions not classified under other codes, indicating the need for medical evaluation, treatment, or monitoring.

Clinical Information

• Liver lesions refer to abnormal areas of tissue in the liver that various conditions, such as tumors, cysts, abscesses, or hemangiomas, can cause.
• The clinical presentation of liver lesions may vary depending on their underlying etiology, size, and location.
• Common symptoms associated with liver lesions include abdominal pain or discomfort, hepatomegaly (enlarged liver), jaundice (yellowing of the skin and eyes), unexplained weight loss, fatigue, and changes in appetite.
• Diagnostic evaluation of liver lesions involves a combination of imaging studies such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and sometimes liver biopsy for definitive diagnosis.
• Treatment approaches for liver lesions depend on the underlying cause. They may include watchful waiting, medication, surgical removal, ablation techniques (such as radiofrequency or microwave ablation), embolization procedures, or liver transplantation.
• Liver lesions can have various etiologies, including primary liver cancer (hepatocellular carcinoma), metastatic cancer from other organs, benign liver tumors (such as adenomas or hemangiomas), liver cysts, liver abscesses, focal nodular hyperplasia (FNH), or other rare liver diseases.
• Managing liver lesions requires a multidisciplinary approach involving hepatologists, gastroenterologists, radiologists, surgeons, oncologists, and other healthcare professionals.
• Regular follow-up and monitoring are often necessary for individuals with liver lesions to assess their growth, changes in characteristics, or potential complications.
• Prognosis and outcomes for liver lesions vary depending on the specific diagnosis, stage of disease, and individual patient factors. Early detection, accurate diagnosis, and timely intervention can significantly impact treatment success and long-term outcomes.

• Liver tumors
• Hepatic lesions
• Liver masses
• Liver nodules
• Liver growths
