ICD-10 Code K22.7 – Barrett’s Esophagus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K22.7 – Barrett’s esophagus
What it is
K22.7 identifies Barrett’s esophagus, a change in the lining of the lower esophagus caused by chronic reflux. You use it when documentation confirms Barrett’s metaplasia.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the diagnosis is confirmed by endoscopy and biopsy showing intestinal metaplasia in the esophagus.
When to use this code
Use K22.7 when the record states Barrett’s esophagus, Barrett’s mucosa, or Barrett’s metaplasia. Code it based on confirmed provider documentation, even if the patient has few or no symptoms. If the note only mentions reflux or esophagitis without Barrett’s, this code is not supported.
Do not use for
Do not use K22.7 for uncomplicated gastroesophageal reflux disease or nonspecific esophagitis. Check documentation if Barrett’s is suspected but not confirmed.
Coding tip
Look for biopsy-confirmed Barrett’s or explicit provider diagnosis before assigning K22.7.
