2024 ICD-10-CM Diagnosis Code C22.0

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Adult hepatocellular carcinoma
• Combined hepatocellular carcinoma and cholangiocarcinoma
• Fibrolamellar hepatocellular carcinoma
• Liver cell carcinoma
• Metastatic hepatocellular carcinoma
• Pediatric hepatocellular carcinoma
• Primary combined hepatocellular carcinoma and cholangiocarcinoma
• Primary fibrolamellar hepatocellular carcinoma
• Primary liver cell carcinoma

Clinical Information

• Metastatic Hepatocellular Carcinoma

  a hepatocellular carcinoma that has spread to another anatomic site.

C22.0 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
435	MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH MCC	07	1.7599
436	MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH CC	07	1.1007
437	MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITHOUT CC/MCC	07	0.8311

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert C22.0 to ICD-9-CM

• ICD-9-CM Code: 155.0 - Mal neo liver, primary
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Filter table of neoplasms:

Neoplasm, neoplastic	Malignant Primary	Malignant Secondary	CaInSitu	Benign	Uncertain Behavior	Unspecified Behavior
»Neoplasm, neoplastic   »hepatoma	C22.0	C78.7	D01.5	D13.4	D37.6	D49.0

Patient Education

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 :

• Having hepatitis B or C
• Heavy alcohol use
• Having cirrhosis, or scarring of the liver
• Having hemochromatosis, an iron storage disease
• Obesity and diabetes

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.
