2022 ICD-10-CM Code C23
Malignant neoplasm of gallbladder
Code Classification
C23 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of gallbladder. The code C23 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C23 might also be used to specify conditions or terms like carcinoma of gallbladder, gallbladder tnm finding, gallbladder tnm finding, gallbladder tnm finding, gallbladder tnm finding , local recurrence of malignant tumor of gallbladder, etc.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: gallbladder .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoma of gallbladder
- Gallbladder TNM finding
- Gallbladder TNM finding
- Gallbladder TNM finding
- Gallbladder TNM finding
- Local recurrence of malignant tumor of gallbladder
- Malignant mesenchymal neoplasm of gallbladder
- Malignant tumor of gallbladder
- Metastasis from malignant tumor of gallbladder
- Primary adenocarcinoma of gallbladder
- Primary malignant neoplasm of gallbladder
- pT1: Tumor invades lamina propria or muscle layer
- pT1a: Tumor invades lamina propria
- pT1b: Tumor invades muscle layer
- pT2: Tumor invades perimuscular connective tissue; no extension beyond serosa or into liver
- pT3: Tumor perforates the serosa
- pT4: Tumor invades main portal vein or hepatic artery or invades two or more extrahepatic organs or structures
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C23 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 435 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH MCC | 07 | 1.7528 |
| 436 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITH CC | 07 | 1.1202 |
| 437 | MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITHOUT CC/MCC | 07 | 0.8945 |
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
The code C23 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.
| Neoplasm, neoplastic | Malignant Primary |
Malignant Secondary |
CaInSitu | Benign | Uncertain Behavior |
Unspecified Behavior |

Information for Patients
Gallbladder Cancer
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.
Cancer of the gallbladder is rare. It is more common in women and Native Americans. Symptoms include
- Jaundice (yellowing of the skin and whites of the eyes)
- Pain above the stomach
- Fever
- Nausea and vomiting
- Bloating
- Lumps in the abdomen
It is hard to diagnose gallbladder cancer in its early stages. Sometimes doctors find it when they remove the gallbladder for another reason. But people with gallstones rarely have gallbladder cancer. Because it is often found late, it can be hard to treat gallbladder cancer. Treatment options include surgery, chemotherapy, radiation, or a combination.
