ICD-10 Code D31.92 – Benign neoplasm of unspecified part of left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.92 – Benign neoplasm of unspecified part of left eye
What it is
This code identifies a noncancerous growth in an unspecified part of the left eye. Use it when the record confirms a benign neoplasm but does not name the exact ocular structure.
Clinical signs
Clinical features vary; refer to documentation. Benign eye tumors may be found on examination, imaging, or ophthalmology evaluation, and they are typically described as localized, nonmalignant lesions.
When to use this code
Use D31.92 when the provider documents a benign neoplasm of the left eye and the exact site is not specified. It also fits when the note says the lesion is in the left eye but does not identify conjunctiva, eyelid, cornea, or another structure. If the record gives a more specific location, code that site instead.
Do not use for
Do not use this code for malignant eye tumors, inflammatory lesions, or traumatic masses. If documentation identifies a different eye structure or a non-neoplastic condition, choose the more accurate code.
Coding tip
Check the ophthalmology note for the exact anatomic site before assigning an unspecified-eye code.
