Malignant neoplasm of choroid

This code signifies a cancerous tumor originating in the choroid, the vascular layer of the eye located between the retina and the sclera. It represents a primary malignancy of this specific ocular structure.

Apply this code when documentation clearly states a diagnosis of malignant neoplasm of the choroid, often identified through ophthalmoscopy, imaging studies (e.g., ultrasound, MRI), and confirmed by biopsy. This code is appropriate for initial diagnosis and ongoing treatment of the primary tumor.

• Ensure documentation specifies "malignant" and "choroid" to differentiate from benign tumors or malignancies of other ocular structures.
• Do not use for secondary metastatic tumors to the choroid; a separate code for the primary site and secondary malignancy of the eye would be appropriate.
• Consider sequencing rules for neoplasms, typically coding the primary malignancy first, unless treatment is directed at a secondary site.
