Malignant neoplasm of right conjunctiva

This code signifies a primary cancerous tumor originating in the conjunctiva of the right eye. The conjunctiva is the transparent membrane that lines the eyelid and covers the white part of the eyeball. This malignancy can manifest in various histological types, such as squamous cell carcinoma or melanoma.

Apply this code when documentation confirms a primary malignant neoplasm affecting the right conjunctiva. This typically follows a biopsy and pathological confirmation of malignancy. Supporting documentation should include the laterality (right eye) and the definitive diagnosis of a primary malignant tumor.

• Differentiate between primary (C69.01) and secondary (C79.x) malignant neoplasms of the conjunctiva.
• Ensure the documentation clearly specifies "right" conjunctiva; if unspecified, query the provider.
• Code any associated symptoms or complications, such as pain or vision changes, as secondary diagnoses.
