ICD-10 Code D31.10 – Benign neoplasm of unspecified cornea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.10 – Benign neoplasm of unspecified cornea
What it is
This code identifies a noncancerous tumor of the cornea when the exact corneal site is not documented. It indicates a benign growth on the clear front surface of the eye.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe a visible corneal mass, surface irregularity, or an incidental finding on eye examination.
When to use this code
Use D31.10 when the record clearly states a benign neoplasm of the cornea but does not specify whether it is central, peripheral, or another location. You may also use it when the provider documents a benign corneal tumor without further detail. Check documentation if the lesion is described as uncertain or if a different corneal condition is named.
Do not use for
Do not use this code for malignant, premalignant, inflammatory, or traumatic corneal lesions. If the diagnosis names a specific corneal site, code the more specific option instead.
Coding tip
Query for laterality or exact corneal location when the note is vague, because a more specific code may be available.
