Congenital dilatation of esophagus

This code represents a congenital anomaly characterized by an abnormal and persistent widening or distension of the esophagus from birth. This condition is distinct from acquired esophageal dilations and often presents with symptoms related to impaired food passage.

Use this code when documentation clearly indicates a diagnosis of congenital esophageal dilatation. This typically involves findings from imaging studies (e.g., barium swallow, endoscopy) confirming the congenital nature and extent of the esophageal widening.

• Differentiate from acquired esophageal dilatation (e.g., due to achalasia or stricture) which would be coded elsewhere.
• Ensure documentation specifies "congenital" to support the use of this code.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
