ICD-10 Code K22.4 – Dyskinesia of esophagus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K22.4 – Dyskinesia of esophagus
What it is
K22.4 identifies dyskinesia of the esophagus, a disorder of abnormal esophageal muscle movement. It means the esophagus does not contract or relax in the usual coordinated way, which can affect swallowing.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include dysphagia, chest discomfort, regurgitation, or abnormal motility on esophageal testing.
When to use this code
Use K22.4 when the provider documents esophageal dyskinesia, abnormal esophageal motility, or a named motility disorder of the esophagus. Code it when the diagnosis is established and supported by the record. Check documentation if the note only describes symptoms without a specific motility diagnosis.
Do not use for
Do not use this code for nonspecific dysphagia, reflux alone, or esophageal obstruction without documented dyskinesia. If the record points to another esophageal disorder, code that condition instead.
Coding tip
Look for the provider’s exact motility diagnosis and avoid assigning K22.4 from test results alone unless the interpretation supports dyskinesia.
