ICD10 code of Eosinophilic Gastroenteritis and ICD9 code

Eosinophilic Gastroenteritis is classified under ICD-10 code K52.81, while its historical ICD-9 billing code is 558.41. These codes are essential for healthcare providers to document this rare condition accurately for insurance and clinical record-keeping purposes.

What is Eosinophilic Gastroenteritis?

Eosinophilic Gastroenteritis is a rare, chronic inflammatory condition characterized by the infiltration of eosinophils—a type of white blood cell—into the walls of the gastrointestinal tract. Unlike standard digestive issues, Eosinophilic Gastroenteritis often presents as a complex allergic or immune-mediated response that can affect the stomach, small intestine, or large intestine, leading to significant abdominal pain, nausea, and weight loss.

How is Eosinophilic Gastroenteritis diagnosed?

Diagnosis of Eosinophilic Gastroenteritis typically requires a combination of clinical evaluation and tissue analysis. Physicians usually rely on the following methods to reach a definitive diagnosis:

• Endoscopy and Biopsy: The gold standard for identifying Eosinophilic Gastroenteritis, involving the collection of tissue samples to count eosinophils per high-power field (hpf).


• Blood Tests: Checking for peripheral eosinophilia, although it is not present in all cases.


• Exclusion of Other Diseases: Ruling out parasitic infections, inflammatory bowel disease (IBD), and celiac disease which can mimic Eosinophilic Gastroenteritis symptoms.

How does the community support those with Eosinophilic Gastroenteritis?

Living with a rare digestive disorder can be isolating, but you are not alone.
