Dyskinesia of esophagus

This code represents a motility disorder of the esophagus characterized by uncoordinated or abnormal contractions of the esophageal muscles. This dyskinesia can lead to impaired food transport from the pharynx to the stomach, often resulting in dysphagia, chest pain, or regurgitation. It encompasses various primary esophageal motility disorders, excluding achalasia and spasm.

Use this code when documentation specifies esophageal dyskinesia, uncoordinated esophageal contractions, or other non-specific esophageal motility disorders. This code is appropriate when diagnostic studies, such as esophageal manometry, confirm abnormal peristalsis or uncoordinated muscular activity without meeting criteria for other specific motility disorders.

• Differentiate from esophageal spasm (350.5) and achalasia (530.0), which have distinct ICD-9-CM codes.
• Ensure documentation clearly states "dyskinesia" or describes uncoordinated esophageal motility, rather than just general dysphagia.
• Consider additional codes for associated symptoms like dysphagia (787.2) or chest pain (786.50) if documented as separate conditions.
