ICD-10 Code D31.2 – Benign neoplasm of retina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.2 – Benign neoplasm of retina
What it is
D31.2 identifies a noncancerous tumor of the retina. It is used when documentation confirms a benign retinal neoplasm, not a malignant or unspecified eye lesion.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a retinal mass or lesion seen on eye examination, with changes in vision if the lesion affects the visual axis or surrounding retina.
When to use this code
Use D31.2 when the provider documents a benign neoplasm specifically arising from the retina. This applies to confirmed retinal tumors described as benign on ophthalmic evaluation, imaging, or pathology if available. If the record only says “eye lesion” or does not specify the site, check documentation before coding.
Do not use for
Do not use this code for malignant retinal tumors or for neoplasms in other parts of the eye. Do not assign it when the lesion is unspecified or when documentation does not confirm a benign retinal origin.
Coding tip
Verify that the note names the retina and states the lesion is benign before assigning D31.2.
