Benign neoplasm of liver and biliary passages

This code signifies the presence of a non-cancerous growth originating in the liver or any part of the biliary system, such as the gallbladder or bile ducts. These benign tumors are typically slow-growing and do not metastasize to other parts of the body.

Use this code when documentation confirms a benign neoplasm of the liver (e.g., hepatic adenoma, focal nodular hyperplasia) or biliary passages (e.g., gallbladder polyp, bile duct adenoma). This diagnosis is often established through imaging studies (ultrasound, CT, MRI) and may be confirmed by biopsy.

• Differentiate carefully between benign and malignant neoplasms; malignant liver/biliary neoplasms have distinct codes.
• Ensure the documentation specifies the benign nature of the growth; "mass" or "lesion" alone is insufficient.
• Consider additional codes for any associated symptoms or complications, if documented.
