Malignant neoplasm of gallbladder (C23)

The ICD-10 code C23 is specifically used to identify malignant neoplasm of the gallbladder, which refers to cancerous tumors originating in this organ. This code is essential for documenting gallbladder cancers in medical records and billing.

This code covers various types of primary gallbladder cancers, including those commonly known as carcinoma of the gallbladder and primary adenocarcinoma of the gallbladder. It also includes more specific forms such as primary squamous cell carcinoma of the gallbladder and extrahepatic biliary tract, and primary malignant mesenchymal neoplasms of the gallbladder. Recognizing these synonyms under C23 helps coders and clinicians correctly assign the code for conditions like local recurrence of malignant tumor of gallbladder or other malignancies linked to the biliary system. Hence, the ICD-10 code C23 represents all primary malignant tumors that arise directly from the gallbladder tissue, providing clear classification for diagnosis, treatment planning, and insurance purposes.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

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.
