Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code K36 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 |
|---|---|---|---|
| 393 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITH MCC | 06 | 1.6536 |
| 394 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITH CC | 06 | 0.9386 |
| 395 | OTHER DIGESTIVE SYSTEM DIAGNOSES WITHOUT CC/MCC | 06 | 0.6497 |
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.

Information for Patients
Appendicitis
The appendix is a small, tube-like organ attached to the first part of the large intestine. It is located in the lower right part of the abdomen. It has no known function. A blockage inside of the appendix causes appendicitis. The blockage leads to increased pressure, problems with blood flow, and inflammation. If the blockage is not treated, the appendix can burst and spread infection into the abdomen. This causes a condition called peritonitis.
The main symptom is pain in the abdomen, often on the right side. It is usually sudden and gets worse over time. Other symptoms may include
- Swelling in the abdomen
- Loss of appetite
- Nausea and vomiting
- Constipation or diarrhea
- Inability to pass gas
- Low fever
Not everyone with appendicitis has all these symptoms.
Appendicitis is a medical emergency. Treatment almost always involves removing the appendix. Anyone can get appendicitis, but it is more common among people 10 to 30 years old.
