Eosinophilic gastritis or gastroenteritis
ICD-10 K52.81 is a billable code used to indicate a diagnosis of eosinophilic gastritis or gastroenteritis.
Eosinophilic gastritis or gastroenteritis is characterized by the infiltration of eosinophils in the gastric or intestinal mucosa, leading to inflammation. Clinically, patients may present with symptoms such as abdominal pain, nausea, vomiting, diarrhea, and weight loss. The condition can affect any part of the gastrointestinal tract but is most commonly seen in the stomach and small intestine. The pathophysiology involves an abnormal immune response, often triggered by food allergens, medications, or infections. Disease progression can vary; some patients may experience acute episodes, while others may have chronic symptoms. Diagnosis typically involves endoscopic evaluation with biopsy to confirm eosinophilic infiltration, along with exclusion of other gastrointestinal disorders. Laboratory tests may also be conducted to identify potential allergens or underlying conditions contributing to eosinophilia. Accurate diagnosis is crucial for effective management, which may include dietary modifications, corticosteroids, or other immunosuppressive therapies.

K52.81 specifically covers eosinophilic gastritis and gastroenteritis, which are conditions characterized by eosinophilic infiltration in the gastric or intestinal mucosa. It is essential to differentiate these conditions from other forms of gastritis or gastroenteritis that do not involve eosinophils.
K52.81 should be used when there is confirmed eosinophilic infiltration in the gastrointestinal tract, as evidenced by biopsy. It is important to differentiate it from other gastrointestinal disorders such as non-eosinophilic gastritis (K29.70) or eosinophilic colitis (K52.82) based on the location and histological findings.
Documentation for K52.81 should include a comprehensive clinical history, symptom descriptions, results from endoscopic evaluations, and biopsy findings confirming eosinophilic infiltration. Additional laboratory tests identifying potential allergens may also support the diagnosis.
