Clinical Information

• Cholangitis

  inflammation of the biliary ductal system (bile ducts); intrahepatic, extrahepatic, or both.

• Cholangitis, Sclerosing

  chronic inflammatory disease of the biliary tract. it is characterized by fibrosis and hardening of the intrahepatic and extrahepatic biliary ductal systems leading to bile duct strictures, cholestasis, and eventual biliary cirrhosis.

• Liver Cirrhosis, Biliary

  fibrosis of the hepatic parenchyma due to obstruction of bile flow (cholestasis) in the intrahepatic or extrahepatic bile ducts (bile ducts, intrahepatic; bile ducts, extrahepatic). primary biliary cholangitis involves the destruction of small intra-hepatic bile ducts and decreased bile secretion. secondary biliary cholangitis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.

• Pericholangitis

  inflammation of the tissue surrounding the biliary ducts.

• Ascending Cholangitis

  acute infection of the bile ducts caused by bacteria ascending from the small intestine.

• Acute Cholangitis

  cholangitis that is both sudden in onset and of a relatively short duration.

• Chronic Cholangitis

  cholangitis that is persistent and long-standing.

K83.09 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
444	DISORDERS OF THE BILIARY TRACT WITH MCC	07	1.6332
445	DISORDERS OF THE BILIARY TRACT WITH CC	07	1.0868
446	DISORDERS OF THE BILIARY TRACT WITHOUT CC/MCC	07	0.8015

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.

Replacement Code

K8309 replaces the following previously assigned ICD-10-CM code(s):

• K83.0 - Cholangitis

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.
