What ICD-10 Codes are Used for Acute Gastroenteritis
Here's a list of the three Acute Gastroenteritis ICD Codes commonly used for billing and coding:
- A08.11: Acute gastro enteropathy due to Norwalk agent
Norwalk agent refers to noroviruses, a group of viruses known for causing acute gastroenteritis.
- A08.19: Acute gastro enteropathy due to other small round viruses
Though the Norwalk agent is a small round virus, one can only use this code for other similarly shaped viruses that aren't the Novovirus, like the calicivirus.
- K52.9: Noninfective gastroenteritis and colitis, unspecified
According to the synonyms, practitioners can use this code if noninfective organisms cause acute gastroenteritis.
Do note that a patient may still have acute gastroenteritis. However, it’s caused by other viruses. If so, please refer to the other specific ICD codes under A08: Viral and other specified intestinal infections.
