Clinical InformationClinical
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)

Patient EducationClinical
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.

Questions About D01.5Overview
Is D01.5 (Carcinoma in situ of other and unspecified digestive organs) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report carcinoma in situ of liver, gallbladder and bile ducts on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D01.5 group to?
When carcinoma in situ of liver, gallbladder and bile ducts is the principal diagnosis on an inpatient stay, it groups to MS-DRG 435, 436, 437, with relative weights from 0.8533 to 1.8367 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of D01.5?
Under the General Equivalence Mappings, carcinoma in situ of liver, gallbladder and bile ducts converts to ICD-9-CM 230.8 (ca in situ liver/biliary). The mapping is a direct match.
