ICD-10 Code D31.41 – Benign neoplasm of right ciliary body (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.41 – Benign neoplasm of right ciliary body
What it is
This code identifies a noncancerous tumor of the ciliary body in the right eye. Use it when documentation specifies a benign neoplasm at that exact anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an ocular mass noted on exam or imaging, with possible visual disturbance or no symptoms at all.
When to use this code
Use D31.41 when the provider documents a benign neoplasm of the right ciliary body, including a confirmed diagnosis from ophthalmology or pathology. It is appropriate for encounters focused on evaluation, monitoring, or follow-up of that lesion. If the record only says “eye tumor” or the site is unclear, check documentation.
Do not use for
Do not use this code for malignant tumors, uncertain behavior, or lesions in a different part of the eye. If the documentation does not specify the right ciliary body, verify the exact location before coding.
Coding tip
Always confirm laterality and the exact ocular site in the note before assigning D31.41.
