Clinical Information

• Ampulla of Vater

  a dilation of the duodenal papilla that is the opening of the juncture of the common bile duct and the main pancreatic duct, also known as the hepatopancreatic ampulla.

• Acalculous Cholecystitis

  inflammation of the gallbladder wall in the absence of gallstones.

• Biliary Dyskinesia

  a motility disorder characterized by biliary colic, absence of gallstones, and an abnormal gallbladder ejection fraction. it is caused by gallbladder dyskinesia and/or sphincter of oddi dysfunction.

• Cholecystitis

  inflammation of the gallbladder; generally caused by impairment of bile flow, gallstones in the biliary tract, infections, or other diseases.

• Gallbladder

  a storage reservoir for bile secretion. gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the cystic duct to the duodenum, for degradation of dietary lipid.

• Gallbladder Diseases

  diseases of the gallbladder. they generally involve the impairment of bile flow, gallstones in the biliary tract, infections, neoplasms, or other diseases.

• Gallbladder Emptying

  a process whereby bile is delivered from the gallbladder into the duodenum. the emptying is caused by both contraction of the gallbladder and relaxation of the sphincter mechanism at the choledochal terminus.

• Gallbladder Neoplasms

  tumors or cancer of the gallbladder.

• Hep G2 Cells

  a human liver tumor cell line used to study a variety of liver-specific metabolic functions.

• Hepatoblastoma

  a malignant neoplasm occurring in young children, primarily in the liver, composed of tissue resembling embryonal or fetal hepatic epithelium, or mixed epithelial and mesenchymal tissues. (stedman, 25th ed)

• Hemangioendothelioma

  a neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). they affect men and women about equally and rarely develop in childhood. (from stedman, 25th ed; holland et al., cancer medicine, 3d ed, p1866)

• Hemangioendothelioma, Epithelioid

  a tumor of medium-to-large veins, composed of plump-to-spindled endothelial cells that bulge into vascular spaces in a tombstone-like fashion. these tumors are thought to have "borderline" aggression, where one-third develop local recurrences, but only rarely metastasize. it is unclear whether the epithelioid hemangioendothelioma is truly neoplastic or an exuberant tissue reaction, nor is it clear if this is equivalent to kimura's disease (see angiolymphoid hyperplasia with eosinophilia). (segen, dictionary of modern medicine, 1992)

• Angiolymphoid Hyperplasia with Eosinophilia

  solitary or multiple benign cutaneous nodules comprised of immature and mature vascular structures intermingled with endothelial cells and a varied infiltrate of eosinophils, histiocytes, lymphocytes, and mast cells.

D37.6 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.

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.

Patient Education

Bile Duct Diseases

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.

Different diseases can block the bile ducts and cause a problem with the flow of bile:

• Gallstones, which can increase pressure in the gallbladder and cause a gallbladder attack. The pain usually lasts from one to several hours.
• Cancer
• Infections
• Birth defects, such as biliary atresia. It is the most common reason for liver transplants in children in the United States.
• Inflammation, which can cause scarring. Over time, this can lead to liver failure.

Gallbladder Diseases

Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.

Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the bile ducts. That is usually a gallstone. Gallstones form when substances in bile harden. Rarely, you can also get cancer in your gallbladder.

Many gallbladder problems get better with removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways of reaching your small intestine.

Liver Diseases

Your liver is the largest organ inside your body. It helps your body digest food, store energy, and remove poisons.

There are many kinds of liver diseases:

• Diseases caused by viruses, such as hepatitis A, hepatitis B, and hepatitis C
• Diseases caused by drugs, poisons, or too much alcohol. Examples include fatty liver disease and cirrhosis.
• Liver cancer
• Inherited diseases, such as hemochromatosis and Wilson disease

Symptoms of liver disease can vary, but they often include swelling of the abdomen and legs, bruising easily, changes in the color of your stool and urine, and jaundice, or yellowing of the skin and eyes. Sometimes there are no symptoms. Tests such as imaging tests and liver function tests can check for liver damage and help to diagnose liver diseases.
