ICD-10 Code K22.8 – Other specified diseases of esophagus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K22.8 – Other specified diseases of esophagus
What it is
K22.8 identifies esophageal disorders that are documented but do not fit a more specific ICD-10-CM category. Use it for named esophageal conditions when the record supports “other specified” disease of the esophagus.
Clinical signs
Clinical features vary; refer to documentation. Patients may have dysphagia, pain with swallowing, reflux-related symptoms, or other esophageal complaints, but the record should identify the condition as a specific esophageal disease.
When to use this code
Use K22.8 when the provider documents an esophageal disorder that is not indexed elsewhere and is not simply a symptom. It is appropriate when the diagnosis is clearly established, but a more specific code is unavailable. Check documentation if the note only describes nonspecific esophageal symptoms.
Do not use for
Do not use this code for common symptoms such as dysphagia, chest pain, or reflux without a documented diagnosis. If the condition has a more specific ICD-10-CM code, code that instead.
Coding tip
Verify the exact provider wording and confirm that the condition is a diagnosed esophageal disease, not just a symptom or an unspecified complaint.
