ICD Code A08.11

ICD code A08.11 is used to classify and code a diagnosis of acute gastroenteropathy caused by the Norwalk agent, which is a type of norovirus. This condition typically involves inflammation of the stomach and intestines, leading to symptoms such as nausea, vomiting, diarrhea, and abdominal pain. The Norwalk agent is a common cause of viral gastroenteritis outbreaks, particularly in settings like cruise ships, schools, and nursing homes. Accurate coding of this condition is essential for healthcare providers to ensure proper documentation, treatment planning, and billing processes.

When considering the use of the ICD code for acute gastroenteropathy due to Norwalk agent, healthcare providers should evaluate the following diagnostic criteria and symptoms:

1. Sudden Onset of Symptoms: The patient experiences a rapid onset of gastrointestinal symptoms, typically within 12 to 48 hours after exposure.

2. Nausea and Vomiting: The patient presents with frequent episodes of nausea and vomiting, which are common initial symptoms.

3. Diarrhea: The patient has watery, non-bloody diarrhea, which may occur multiple times a day.

4. Abdominal Pain and Cramps: The patient reports abdominal discomfort, including cramping and pain.

5. Low-Grade Fever: The patient may have a mild fever, although it is not always present.

6. Dehydration Signs: The patient shows signs of dehydration, such as dry mouth, decreased urination, and dizziness, especially if fluid loss is significant.

7. Recent Exposure History: The patient has a history of recent exposure to contaminated food, water, or close contact with an infected individual, often in settings like cruise ships, schools, or nursing homes.

8. Short Duration of Illness: The symptoms typically resolve within 1 to 3 days, indicating a self-limiting condition.

9. Exclusion of Other Causes: Other potential causes of gastroenteritis, such as bacterial infections or other viral agents, have been ruled out through clinical evaluation and, if necessary, laboratory testing.

By assessing these criteria, healthcare providers can accurately determine the use of the ICD code for acute gastroenteropathy due to Norwalk agent.
