Malignant neoplasm of eyeball, except conjunctiva, cornea, retina, and choroid

This code signifies a primary cancerous tumor originating in the eyeball, specifically excluding the conjunctiva, cornea, retina, and choroid. This includes malignancies affecting structures like the sclera, ciliary body, iris, or vitreous body.

Apply this code when documentation confirms a primary malignant neoplasm of the globe, with specific exclusion of the conjunctiva, cornea, retina, and choroid. Common scenarios include melanoma of the iris or ciliary body, or other rare primary sarcomas of the sclera.

• Ensure the pathology report or physician documentation explicitly states "malignant neoplasm" and specifies the eyeball as the primary site, excluding the listed structures.
• Differentiate from secondary malignant neoplasms of the eyeball, which would be coded differently.
• Carefully review documentation to rule out involvement of the conjunctiva, cornea, retina, or choroid, as these have specific codes.
