Malignant neoplasm of lower third of esophagus

This code signifies a cancerous tumor originating in the distal third of the esophagus, specifically the portion closest to the stomach. This malignancy is characterized by uncontrolled cell growth within the esophageal lining, impacting its function and potentially metastasizing.

Apply this code when documentation clearly indicates a primary malignant neoplasm located in the lower third of the esophagus. Supporting documentation includes pathology reports confirming malignancy and precise anatomical location, as well as physician notes detailing the tumor's site.

• Ensure the documentation specifies "lower third" or "distal" esophagus to differentiate from other esophageal segments.
• Do not use for benign neoplasms or carcinoma in situ; these have distinct codes.
• Sequence as the primary diagnosis when the esophageal malignancy is the reason for the encounter.
