Benign neoplasm of cornea

This code identifies a non-cancerous growth or tumor affecting the transparent outer layer of the eye, the cornea. These benign lesions are typically slow-growing and do not metastasize, but can impact vision depending on their size and location.

Apply this code when documentation clearly indicates a benign corneal neoplasm, such as a dermoid, papilloma, or nevus. Supporting documentation should include ophthalmological examination findings, and often, a pathology report confirming benignity.

• Ensure the documentation explicitly states "benign" to differentiate from malignant corneal neoplasms.
• Do not use for inflammatory or degenerative corneal conditions; these have distinct ICD-9-CM codes.
• If the specific type of benign neoplasm is known (e.g., corneal dermoid), consider if a more specific ICD-9-CM code exists, though 224.4 is often appropriate for unspecified benign corneal tumors.
