Malignant neoplasm of thoracic esophagus

This code signifies a cancerous tumor originating in the middle section of the esophagus, specifically the thoracic portion. This malignancy involves uncontrolled growth of abnormal cells within the esophageal lining, potentially invading deeper tissues and metastasizing.

Assign this code when documentation clearly indicates a primary malignant neoplasm located in the thoracic esophagus. This diagnosis is typically confirmed through biopsy and imaging studies such as CT scans or endoscopy with tissue sampling.

• Ensure the documentation specifies "thoracic" esophagus; other esophageal locations have different codes.
• Do not use for benign neoplasms or carcinoma in situ of the esophagus.
• Sequence as the primary diagnosis when the patient is receiving treatment for this malignancy.
