Acute gastroenteritis, also known as stomach flu or viral gastroenteritis, is characterized by infectious diarrhea. Learn about clinical documentation, medical coding, and healthcare best practices for diagnosing and managing acute gastroenteritis. This resource provides information for healthcare professionals on proper coding and documentation related to stomach flu and infectious diarrhea, supporting accurate clinical records and improved patient care.
Also known as
Other viral intestinal infections
Covers viral gastroenteritis and other specified intestinal infections.
Intestinal infectious diseases
Includes cholera, typhoid, and other bacterial and viral intestinal infections.
Symptoms and signs involving the digestive system and abdomen
Includes nausea, vomiting, diarrhea, and other abdominal symptoms.
Other noninfective gastroenteritis and colitis
Includes gastroenteritis and colitis not caused by infectious agents.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the gastroenteritis infectious?
Yes
Is pathogen specified?
No
Do NOT code as gastroenteritis. Consider other diagnoses (e.g., K52.9).
When to use each related code
| Description |
|---|
| Inflammation of the stomach and intestines, often viral. |
| Inflammation of the stomach lining, various causes. |
| Inflammation of the small intestine, often chronic. |
Coding acute gastroenteritis without specifying the pathogen (viral, bacterial, etc.) can lead to rejected claims or lower reimbursement.
Insufficient documentation of dehydration level (mild, moderate, severe) impacts accurate coding and severity-based reimbursement.
Symptoms suggesting alternative diagnoses (appendicitis, pancreatitis) require careful evaluation to avoid inaccurate gastroenteritis coding.
Q: What are the most effective differential diagnosis strategies for acute gastroenteritis in adults presenting with severe dehydration?
A: Differentiating acute gastroenteritis (AGE) from other conditions presenting with severe dehydration in adults requires a systematic approach. Consider the patient's history, including travel, recent antibiotic use, and dietary habits. Physical exam findings like fever, abdominal tenderness, and character of stools (bloody, watery, mucousy) offer crucial clues. Laboratory investigations, including complete blood count (CBC), stool cultures for bacterial pathogens and ova and parasites, and serum electrolytes to assess dehydration severity, are essential. For patients with severe dehydration presenting with persistent vomiting, consider checking serum amylase and lipase to rule out pancreatitis. In cases with bloody diarrhea, consider inflammatory bowel disease (IBD) or ischemic colitis and request further imaging studies like CT abdomen/pelvis if clinically indicated. Explore how integrating these strategies can improve diagnostic accuracy in complex AGE cases.
Q: How do I manage acute gastroenteritis in a pediatric patient with persistent vomiting and signs of moderate dehydration who refuses oral rehydration?
A: Managing a pediatric patient with acute gastroenteritis (AGE), persistent vomiting, and moderate dehydration who refuses oral rehydration solution (ORS) can be challenging. Begin by educating the parents/caregivers about the importance of rehydration. Try offering small, frequent sips of ORS, ice chips, or popsicles. If oral rehydration fails, consider administering intravenous (IV) fluids for rapid rehydration. Ondansetron can be helpful for controlling vomiting, making ORS administration more successful. Monitor the child’s vital signs and urine output closely for signs of improvement or worsening dehydration. If the child develops signs of severe dehydration, hospitalization may be necessary. Consider implementing a stepped approach to rehydration and explore how antiemetic medications can aid in successful ORS administration.

Patient presents with acute onset of gastroenteritis, clinically manifesting as stomach flu with symptoms consistent with infectious diarrhea. The patient reports experiencing nausea, vomiting, and watery diarrhea. Onset of symptoms began approximately [Number] hours/days prior to presentation. The patient denies bloody stools, fever, or severe abdominal pain. Physical examination reveals mild dehydration evidenced by dry mucous membranes. Abdomen is soft and non-tender with normoactive bowel sounds. Differential diagnoses considered include viral gastroenteritis, bacterial gastroenteritis, and food poisoning. Given the patient's presentation and lack of concerning findings, the diagnosis of acute gastroenteritis is most likely. Treatment plan includes oral rehydration therapy with electrolyte solutions, a bland diet, and symptomatic management of nausea and vomiting with antiemetics as needed. Patient education provided regarding proper hand hygiene and food safety to prevent transmission. Follow-up care recommended if symptoms worsen or persist beyond [Number] days. ICD-10 code A08.4 (viral intestinal infection) is the working diagnosis code, pending further evaluation. This diagnosis aligns with medical billing and coding guidelines for acute gastroenteritis.
