Specific Coding for Malignant neoplasm of liver and intrahepatic bile ducts

Non-specific codes like C22 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for malignant neoplasm of liver and intrahepatic bile ducts:

  • BILLABLE CODE - Use C22.0 for Liver cell carcinoma
  • BILLABLE CODE - Use C22.1 for Intrahepatic bile duct carcinoma
  • BILLABLE CODE - Use C22.2 for Hepatoblastoma
  • BILLABLE CODE - Use C22.3 for Angiosarcoma of liver
  • BILLABLE CODE - Use C22.4 for Other sarcomas of liver
  • BILLABLE CODE - Use C22.7 for Other specified carcinomas of liver
  • BILLABLE CODE - Use C22.8 for Malignant neoplasm of liver, primary, unspecified as to type
  • BILLABLE CODE - Use C22.9 for Malignant neoplasm of liver, not specified as primary or secondary

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients


Bile Duct Cancer

Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.

Bile duct cancer is rare. It can happen in the parts of the bile ducts that are outside or inside the liver. Cancer of the bile duct outside of the liver is much more common. Risk factors include having inflammation of the bile duct, ulcerative colitis, and some liver diseases.

Symptoms can include

Tests to diagnose bile duct cancer may include a physical exam, imaging tests of the liver and bile ducts, blood tests, and a biopsy.

Treatments include surgery, radiation therapy, and chemotherapy.

Liver Cancer

Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons. Primary liver cancer starts in the liver. Metastatic liver cancer starts somewhere else and spreads to your liver.

Risk factors for primary liver cancer include

Symptoms can include a lump or pain on the right side of your abdomen and yellowing of the skin. However, you may not have symptoms until the cancer is advanced. This makes it harder to treat. Doctors use tests that examine the liver and the blood to diagnose liver cancer. Treatment options include surgery, radiation, chemotherapy, or liver transplantation.
