Short answer · Medically reviewed summary · Last updated: 2026-05-08
The primary diagnostic code for Eosinophilic esophagitis is ICD-10-CM K20.0, which specifically designates eosinophilic esophagitis. Under the older ICD-9-CM classification system, Eosinophilic esophagitis was typically coded as 530.13, reflecting its status as an eosinophilic condition of the esophagus. Why are medical codes for Eosinophilic esophagitis important? Accurate coding for Eosinophilic esophagitis is essential for ensuring appropriate insurance coverage for diagnostic endoscopies, biopsies, and the subsequent management of the disease.

ICD10 code of Eosinophilic esophagitis and ICD9 code
ICD-10 and ICD-9 codes for Eosinophilic esophagitis, with classification details for clinicians, coders and patients.
The primary diagnostic code for Eosinophilic esophagitis is ICD-10-CM K20.0, which specifically designates eosinophilic esophagitis. Under the older ICD-9-CM classification system, Eosinophilic esophagitis was typically coded as 530.13, reflecting its status as an eosinophilic condition of the esophagus.
Why are medical codes for Eosinophilic esophagitis important?
Accurate coding for Eosinophilic esophagitis is essential for ensuring appropriate insurance coverage for diagnostic endoscopies, biopsies, and the subsequent management of the disease. Because Eosinophilic esophagitis is a chronic, immune-mediated condition, having the correct ICD-10 code (K20.0) allows healthcare providers to track the long-term progression of the condition and justify specialized treatments, such as swallowed topical corticosteroids or elimination diets, within clinical databases.
How is Eosinophilic esophagitis confirmed?
A diagnosis of Eosinophilic esophagitis is confirmed through a combination of clinical symptoms and histological evidence. While ICD codes categorize the disease, the definitive diagnosis requires an upper endoscopy with esophageal biopsies showing a peak eosinophil count of at least 15 eosinophils per high-power field (eos/hpf). Currently, 164 individuals within the DiseaseMaps community have shared their experiences living with Eosinophilic esophagitis, highlighting the importance of standardized documentation in finding effective care pathways.
What should you know about clinical documentation?
When discussing your records with your gastroenterologist, it is helpful to understand how Eosinophilic esophagitis is documented. Key elements often included in medical charts alongside the ICD-10 code K20.0 include:
- Documentation of dysphagia (difficulty swallowing) or food impaction history.
- Results of esophageal biopsies confirming high eosinophil density.
- Records of associated allergic conditions, such as asthma or seasonal allergies, which are highly comorbid with Eosinophilic esophagitis.
- Response to dietary or pharmacological interventions.
Next steps
- Verify that your specialist is using the K20.0 code to ensure accurate tracking in your medical history.
- Consult with a board-certified gastroenterologist or an allergist/immunologist specializing in Eosinophilic esophagitis.
