Malignant neoplasm of cornea

This code signifies a cancerous growth originating in the cornea, the transparent outer layer at the front of the eye. This malignancy can manifest as various histological types, impacting vision and potentially spreading to adjacent ocular structures.

Assign this code when documentation clearly indicates a primary malignant neoplasm confined to the corneal tissue. Supporting documentation includes pathology reports confirming malignancy and the specific anatomical site, as well as ophthalmologist's notes detailing the tumor's location.

• Differentiate from benign corneal tumors or secondary malignancies metastatic to the cornea.
• Ensure the pathology report specifies "cornea" as the primary site, not just "eye."
• Consider sequencing with codes for associated symptoms or complications, such as vision impairment.
