Malignant neoplasm of postcricoid region

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

This code is appropriate for documenting a confirmed diagnosis of a malignant neoplasm located in the postcricoid area. Documentation supporting its use typically includes pathology reports confirming malignancy and the specific anatomical site, as well as physician notes detailing the tumor's location.

• Ensure documentation clearly specifies "postcricoid region" to differentiate from other hypopharyngeal sites.
• Do not confuse with malignancies of the pyriform sinus or posterior wall of the hypopharynx, which have distinct codes.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any relevant secondary diagnoses.
