Eosinophilic esophagitis
ICD-10 K20.0 is a billable code used to indicate a diagnosis of eosinophilic esophagitis.
Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition characterized by eosinophilic infiltration of the esophageal epithelium. Clinically, patients may present with symptoms such as dysphagia, food impaction, chest pain, and heartburn, which can mimic gastroesophageal reflux disease (GERD). The esophagus, the muscular tube connecting the throat to the stomach, becomes inflamed due to an allergic response, often triggered by food allergens or environmental factors. Disease progression can lead to esophageal remodeling, strictures, and impaired swallowing function if left untreated. Diagnosis typically involves endoscopy with biopsy to confirm eosinophilic infiltration, with a threshold of 15 eosinophils per high-power field being diagnostic. Additional considerations include ruling out other causes of eosinophilia and assessing for associated conditions such as asthma or allergic rhinitis. Management often includes dietary modifications, topical corticosteroids, and in some cases, systemic medications, emphasizing the need for a multidisciplinary approach to care.

K20.0 specifically covers eosinophilic esophagitis, which is characterized by eosinophilic infiltration in the esophagus. It is differentiated from other esophageal conditions by the presence of eosinophils in biopsy samples.
K20.0 should be used when eosinophilic esophagitis is diagnosed based on biopsy results showing eosinophilic infiltration, particularly when symptoms are not responsive to standard GERD treatments.
Documentation for K20.0 should include endoscopic findings, biopsy results indicating eosinophilia, symptom descriptions, and any relevant allergy testing results.
