Malignant neoplasm of cervical esophagus

This code signifies a cancerous tumor originating in the cervical portion of the esophagus. This is the uppermost section of the esophagus, located in the neck, extending from the pharynx to the thoracic inlet. The malignancy can be of various histological types, such as squamous cell carcinoma or adenocarcinoma.

Assign this code when documentation explicitly states a malignant neoplasm located in the cervical esophagus. This diagnosis is typically confirmed by biopsy and imaging studies, such as endoscopy with biopsy, CT scan, or MRI. Use this code for primary malignant tumors, not metastatic disease to the cervical esophagus.

• Differentiate from malignant neoplasms of other esophageal segments (e.g., thoracic, abdominal) which have distinct codes.
• Ensure documentation specifies "cervical" esophagus; otherwise, a more general esophageal malignancy code may be appropriate.
• Code the specific histological type of the neoplasm as an additional diagnosis if known and documented.
