2025 ICD-10-CM code A08.1
Acute gastroenteropathy due to Norwalk agent and other small round viruses.
Medical necessity for services related to A08.1 is established by the presence of symptoms and signs consistent with acute gastroenteritis caused by Norwalk virus or other small round viruses.The severity of symptoms, such as dehydration, may necessitate medical intervention like intravenous fluids.Laboratory testing can be medically necessary to confirm the diagnosis and guide treatment decisions, especially in outbreaks or severe cases.
Clinicians diagnose this condition based on reported symptoms, patient history, and a physical examination.Lab tests, such as blood, stool, or vomit analysis, can help confirm the diagnosis by identifying viral antigens and ruling out bacterial or parasitic causes. Treatment focuses on rehydration, often through oral or intravenous fluids.Antibiotics are not effective against viral infections. Patient education on preventative measures, such as proper handwashing and food hygiene, is also important.
In simple words: This code indicates an infection in your stomach and intestines caused by the Norwalk virus (also known as Norovirus) or a similar virus.These infections are often spread through contaminated food or water, or by close contact with an infected person. Symptoms can include diarrhea, vomiting, stomach pain, and sometimes fever.
This code represents an acute inflammation of the stomach and intestines caused by the Norwalk virus (Norovirus) or other similar small round structured viruses. These viruses are typically transmitted through contaminated food or water, or via person-to-person contact.
Example 1: A 5-year-old child presents with vomiting, diarrhea, and abdominal pain after attending a birthday party where several other children experienced similar symptoms. The physician suspects Norovirus and orders a stool sample for testing., A 25-year-old adult experiences sudden onset of nausea, vomiting, and watery diarrhea after consuming raw oysters.Dehydration develops, requiring intravenous fluid replacement., Several residents of a nursing home develop symptoms consistent with acute gastroenteritis.Infection control measures are implemented to prevent further spread of the suspected Norovirus outbreak.
Documentation should include signs and symptoms, such as vomiting, diarrhea, abdominal pain, nausea, and fever. Details regarding the onset and duration of symptoms, as well as any potential exposure to contaminated food or water or contact with infected individuals, are crucial. Results of laboratory tests, if performed, should be documented, including stool tests and blood work to rule out other causes.The patient's hydration status and any administered treatments, such as oral or intravenous rehydration, should also be noted.
