Code Navigator:
R19.7 is a billable diagnosis code used to specify a medical diagnosis of diarrhea, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.
Unspecified diagnosis codes like R19.7 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.
They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.
CCSR Code: SYM006
Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Diarrhea
an increased liquidity or decreased consistency of feces, such as running stool. fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. diarrhea is not hyperdefecation or increased fecal weight.
Diarrhea Virus 1, Bovine Viral
a species of pestivirus causing systemic infections (bovine virus diarrhea-mucosal disease) in cattle and some other cloven-hoofed animals. there are several strains and two biotypes: cytopathic (rare) and non-cytopathic. infections range from clinically inapparent to severe, but do not correlate with biotypes.
Diarrhea Virus 2, Bovine Viral
a species of pestivirus causing systemic infections including bovine virus diarrhea-mucosal disease and bovine hemorrhagic syndrome in cattle and some other cloven-hoofed animals. there are several strains and two biotypes: cytopathic (rare) and non-cytopathic. the severity of disease appears to be strain dependent. cytopathogenic effects do not correlate with virulence as non-cytopathic bvdv-2 is associated only with hemorrhagic disease, bovine.
Diarrhea Viruses, Bovine Viral
a group of viruses in the genus pestivirus, causing diarrhea, fever, oral ulcerations, hemorrhagic syndrome, and various necrotic lesions among cattle and other domestic animals. the two species (genotypes), bvdv-1 and bvdv-2 , exhibit antigenic and pathological differences. the historical designation, bvdv, consisted of both (then unrecognized) genotypes.
Diarrhea, Infantile
diarrhea occurring in infants from newborn to 24-months old.
Dysentery
acute inflammation of the intestine associated with infectious diarrhea of various etiologies, generally acquired by eating contaminated food containing toxins, biological derived from bacteria or other microorganisms. dysentery is characterized initially by watery feces then by bloody mucoid stools. it is often associated with abdominal pain; fever; and dehydration.
Feces
excrement from the intestines, containing unabsorbed solids, waste products, secretions, and bacteria of the digestive system.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
Diarrhea
What is diarrhea?
Diarrhea is loose, watery stools (bowel movements). You have diarrhea if you have loose stools three or more times in one day. Acute diarrhea is diarrhea that lasts a short time. It is a common problem. It usually lasts about one or two days, but it may last longer. Then it goes away on its own.
Diarrhea lasting more than a few days may be a sign of a more serious problem. Chronic diarrhea -- diarrhea that lasts at least four weeks -- can be a symptom of a chronic disease. Chronic diarrhea symptoms may be continual, or they may come and go.
What causes diarrhea?
The most common causes of diarrhea include:
- Bacteria from contaminated food or water
- Viruses such as the flu, norovirus, or rotavirus . Rotavirus is the most common cause of acute diarrhea in children.
- Parasites, which are tiny organisms found in contaminated food or water
- Medicines such as antibiotics, cancer drugs, and antacids that contain magnesium
- Food intolerances and sensitivities, which are problems digesting certain ingredients or foods. An example is lactose intolerance.
- Diseases that affect the stomach, small intestine, or colon, such as Crohn's disease
- Problems with how the colon functions, such as irritable bowel syndrome
Some people also get diarrhea after stomach surgery, because sometimes the surgeries can cause food to move through your digestive system more quickly.
Sometimes no cause can be found. If your diarrhea goes away within a few days, finding the cause is usually not necessary.
Who is at risk for diarrhea?
People of all ages can get diarrhea. On average, adults In the United States have acute diarrhea once a year. Young children have it an average of twice a year.
People who visit developing countries are at risk for traveler's diarrhea. It is caused by consuming contaminated food or water.
What other symptoms might I have with diarrhea?
Other possible symptoms of diarrhea include:
- Cramps or pain in the abdomen
- An urgent need to use the bathroom
- Loss of bowel control
If a virus or bacteria is the cause of your diarrhea, you may also have a fever, chills, and bloody stools.
Diarrhea can cause dehydration, which means that your body does not have enough fluid to work properly. Dehydration can be serious, especially for children, older adults, and people with weakened immune systems.
When do I need to see a health care provider for diarrhea?
Although it is usually not harmful, diarrhea can become dangerous or signal a more serious problem. Contact your health care provider if you have:
- Signs of dehydration
- Diarrhea for more than 2 days, if you are an adult. For children, contact the provider if it lasts more than 24 hours.
- Severe pain in your abdomen or rectum (for adults)
- A fever of 102 degrees or higher
- Stools containing blood or pus
- Stools that are black and tarry
If children have diarrhea, parents or caregivers should not hesitate to call a health care provider. Diarrhea can be especially dangerous in newborns and infants.
How is the cause of diarrhea diagnosed?
To find the cause of diarrhea, your health care provider may:
- Do a physical exam
- Ask about any medicines you are taking
- Test your stool or blood to look for bacteria, parasites, or other signs of disease or infection
- Ask you to stop eating certain foods to see whether your diarrhea goes away
If you have chronic diarrhea, your health care provider may perform other tests to look for signs of disease.
What are the treatments for diarrhea?
Diarrhea is treated by replacing lost fluids and electrolytes to prevent dehydration. Depending on the cause of the problem, you may need medicines to stop the diarrhea or treat an infection.
Adults with diarrhea should drink water, fruit juices, sports drinks, sodas without caffeine, and salty broths. As your symptoms improve, you can eat soft, bland food.
Children with diarrhea should be given oral rehydration solutions to replace lost fluids and electrolytes.
Can diarrhea be prevented?
Two types of diarrhea can be prevented - rotavirus diarrhea and traveler's diarrhea. There are vaccines for rotavirus. They are given to babies in two or three doses.
You can help prevent traveler's diarrhea by being careful about what you eat and drink when you are in developing countries:
- Use only bottled or purified water for drinking, making ice cubes, and brushing your teeth
- If you do use tap water, boil it or use iodine tablets
- Make sure that the cooked food you eat is fully cooked and served hot
- Avoid unwashed or unpeeled raw fruits and vegetables
