Burn of esophagus

This code signifies thermal or chemical injury to the esophageal lining, resulting in tissue damage. It encompasses burns caused by ingested hot liquids, caustic substances, or other agents that directly injure the esophagus. The severity can range from superficial mucosal damage to full-thickness necrosis.

Apply this code when documentation clearly indicates a burn injury to the esophagus, often following ingestion of a corrosive agent (e.g., lye, strong acids) or extremely hot food/drink. Supporting documentation would include endoscopy reports detailing esophageal injury, patient history of ingestion, and clinical signs/symptoms consistent with esophageal burn.

• Differentiate from other esophageal disorders like esophagitis (530.1x) or stricture (530.3) unless the burn is the direct cause.
• Always code the external cause of the burn (E-code) in addition to this diagnosis code to provide complete context.
• Specify the type of burn (e.g., chemical, thermal) if documented, as this can influence treatment and prognosis.
