2024 ICD-10-CM Diagnosis Code K83.5

Approximate Synonyms

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

• Acquired choledochal cyst
• Acquired cystic dilatation of common bile duct
• Acquired dilation of bile duct
• Choledochal cyst
• Cyst of bile duct
• Cyst of biliary tract
• Cyst of intrahepatic bile ducts
• Cystic dilatation of common bile duct
• Liver cyst

Clinical Information

• Choledochal Cyst

  a congenital anatomic malformation of a bile duct, including cystic dilatation of the extrahepatic bile duct or the large intrahepatic bile duct. classification is based on the site and type of dilatation. type i is most common.

• Bile Duct Mucinous Cystic Neoplasm with an Associated Invasive Carcinoma|Bile Duct Cystadenocarcinoma|Bile Duct MCN with an Associated Invasive Carcinoma|Bile duct cystadenocarcinoma|Biliary Cystadenocarcinoma|Cystadenocarcinoma of Bile Duct|Cystadenocarcinoma of the Bile Duct

  a mucinous cystic neoplasm that arises from the intrahepatic or extrahepatic bile ducts and it is associated with an invasive carcinomatous component.

• Biliary Cyst

  a cystic dilatation that occurs in any part of the biliary tree.

• Choledochal Cyst

  cystic dilatation of the hepatic duct or bile duct.

K83.5 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.

Convert K83.5 to ICD-9-CM

• ICD-9-CM Code: 576.8 - Dis of biliary tract NEC
  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.

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.
