Malignant neoplasm of postcricoid region of hypopharynx

This code signifies a cancerous tumor originating in the postcricoid region, which is the lower part of the hypopharynx situated behind the cricoid cartilage. This is a specific type of head and neck cancer affecting the pharynx.

Use this code when documentation clearly indicates a primary malignant neoplasm located in the postcricoid area of the hypopharynx. This diagnosis is typically established through biopsy and imaging studies.

• Ensure the documentation specifies "postcricoid region" within the hypopharynx; do not use for other hypopharyngeal subsites.
• Confirm the neoplasm is primary and malignant; do not use for benign lesions or metastatic disease to this site.
• Consider sequencing with codes for treatment modalities (e.g., radiation, chemotherapy, surgery) as appropriate.
