BillableEosinophilic gastritis or gastroenteritis

What This Code Means
An allergic inflammation of the stomach and/or small intestine characterized by an abnormal accumulation of eosinophils (a type of white blood cell), causing abdominal pain, nausea, and sometimes vomiting.
Coding Tips
- •Confirm diagnosis with endoscopy and biopsy showing eosinophilic infiltration; document the eosinophil count when available
- •Distinguish between gastritis alone (K52.81) and gastroenteritis; ensure documentation specifies which organs are involved
