ICD-10 Code D31.11 – Benign neoplasm of right cornea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.11 – Benign neoplasm of right cornea
What it is
D31.11 identifies a noncancerous tumor of the right cornea. Use it when documentation states a benign corneal neoplasm limited to the right eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a visible corneal lesion, localized opacity, or surface irregularity noted on eye examination.
When to use this code
Use D31.11 when the provider documents a benign neoplasm specifically in the right cornea. This applies to outpatient, inpatient, and specialist notes when the diagnosis is confirmed or clearly stated.
Assign it only when laterality is documented and the lesion is not described as malignant, inflammatory, traumatic, or unspecified. Check documentation if the record does not clearly identify the cornea or the right eye.
Do not use for
Do not use this code for malignant eye tumors, corneal inflammation, ulcers, or traumatic corneal injuries. If the site or behavior is unclear, check documentation.
Coding tip
Confirm both benign behavior and right-sided corneal location before assigning D31.11.
