ICD-10 Code D31.3 – Benign neoplasm of choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.3 – Benign neoplasm of choroid
What it is
This code identifies a noncancerous tumor of the choroid, the vascular layer beneath the retina. Use it when documentation specifically states a benign choroidal neoplasm.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an incidental choroidal lesion on eye exam, pigment changes, or imaging evidence of a stable, benign-appearing mass.
When to use this code
Use D31.3 when the provider documents a benign neoplasm of the choroid, including cases found during ophthalmic evaluation or imaging. Code it for confirmed benign choroidal tumors, not for suspected lesions without a final diagnosis. If the record is unclear, check documentation.
Do not use for
Do not use this code for malignant choroidal tumors, metastatic disease, or nonspecific retinal findings. If the lesion is not documented as benign, check documentation.
Coding tip
Confirm the exact anatomic site in the note, because choroid, retina, and other ocular structures use different ICD-10 codes.
