Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code C49.A4 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 |
---|---|---|---|
374 | DIGESTIVE MALIGNANCY WITH MCC | 06 | 2.0679 |
375 | DIGESTIVE MALIGNANCY WITH CC | 06 | 1.2049 |
376 | DIGESTIVE MALIGNANCY WITHOUT CC/MCC | 06 | 0.8952 |
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
C49A4 replaces the following previously assigned ICD-10 code(s):

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C49.A4 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Gastrointestinal stromal tumor
A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine. This type of tumor is thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells. Affected individuals can develop one or more tumors. GISTs are usually found in adults between ages 40 and 70; rarely, children and young adults develop this type of tumor.
Small tumors may cause no signs or symptoms. However, some people with GISTs may experience pain or swelling in the belly area (abdomen), nausea, vomiting, loss of appetite, or weight loss. Sometimes, tumors cause bleeding into the gastrointestinal tract, which may lead to low red blood cell counts (anemia) and, consequently, weakness and tiredness. Bleeding into the intestines may cause black and tarry stools, and bleeding into the throat or stomach may cause vomiting of blood.
Affected individuals with no family history of GIST typically have only one tumor (called a sporadic GIST). People with a family history of GISTs (called familial GISTs) often have multiple tumors and additional signs or symptoms, including noncancerous overgrowth (hyperplasia) of other cells in the gastrointestinal tract and patches of dark skin on various areas of the body. Some affected individuals have a skin condition called urticaria pigmentosa (also known as maculopapular cutaneous mastocytosis), which is characterized by raised patches of brownish skin that sting or itch when touched.
A rare form of GIST, called succinate dehydrogenase (SDH)-deficient GIST, tends to occur in childhood or young adulthood and affects females more commonly than males. In this form, tumors are almost always in the stomach. Individuals with an SDH-deficient GIST have a high risk of developing other types of tumors, particularly noncancerous tumors in the nervous system called paragangliomas and noncancerous lung tumors called pulmonary chondromas. When GISTs occur in combination with paragangliomas, the condition is known as Carney-Stratakis syndrome; the combination of GISTs, paragangliomas, and pulmonary chondromas is known as Carney triad; and the combination of GISTs and pulmonary chondroma is known as incomplete Carney triad.
