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). The diagnosis code A00.9 is grouped in the following groups for version MS-DRG V36.0 applicable from 10/01/2018 through 09/30/2019.
- 371 - MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITH MCC
- 372 - MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITH CC
- 373 - MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITHOUT CC/MCC

Information for Patients
Cholera
Cholera is a bacterial infection that causes diarrhea. The cholera bacterium is usually found in water or food that has been contaminated by feces (poop). Cholera is rare in the US. You may get it if you travel to parts of the world with poor water and sewage treatment. Outbreaks can also happen after disasters. The disease is not likely to spread directly from person to person.
Cholera infections are often mild. Some people don't have any symptoms. If you do get symptoms, they usually start 2 to 3 days after infection. The most common symptom is watery diarrhea.
In some cases, the infection can be severe, causing lots of watery diarrhea, vomiting, and leg cramps. Because you quickly lose body fluids, you are at risk for dehydration and shock. Without treatment, you could die within hours. If you think that you might have cholera, you should get medical care right away.
Doctors diagnose cholera with a stool sample or rectal swab. Treatment is the replacement of the fluid and salts that you lost through the diarrhea. This is usually with a rehydration solution that you drink. People with severe cases may need an I.V. to replace the fluids. Some of them may also need antibiotics. Most people who get fluid replacement right away will recover.
There are vaccines to prevent cholera. One of them is available for adults in the U.S. Very few Americans need it, because most people do not visit areas that have an active cholera outbreak.
There are also simple steps you can take to help to prevent cholera infection:
- Use only bottled or purified water for drinking, washing dishes, making ice cubes, and brushing your teeth
- If you do use tap water, boil it or use iodine tablets
- Wash your hands often with soap and clean water
- Make sure that the cooked food you eat is fully cooked and served hot
- Avoid unwashed or unpeeled raw fruits and vegetables

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
- Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
