Malignant neoplasm of right retina

This code signifies a primary cancerous tumor originating in the light-sensitive tissue at the back of the right eye. This malignancy typically affects the photoreceptor cells and can lead to significant vision impairment or loss if not treated.

Use this code for documented cases of primary malignant neoplasm specifically affecting the retina of the right eye. Supporting documentation should clearly state the diagnosis of a primary retinal malignancy and specify the right eye as the affected laterality.

• Ensure documentation explicitly states "primary" malignancy; metastatic lesions to the retina are coded differently.
• Verify laterality (right eye) is clearly documented to avoid miscoding.
• Differentiate from benign retinal neoplasms or other intraocular malignancies affecting different structures.
