ICD-10 Code C69.11 – Malignant neoplasm of right cornea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.11 – Malignant neoplasm of right cornea
What it is
C69.11 identifies a malignant tumor arising in the right cornea, the clear front surface of the eye. Use it when the record specifies cancer of the right cornea.
Clinical signs
Clinical features vary; refer to documentation. Records may note a corneal mass, opacity, surface lesion, or abnormal growth confirmed as malignant by ophthalmic evaluation or pathology.
When to use this code
Use this code when the provider documents a primary malignant neoplasm of the right cornea. It is appropriate for confirmed cases, including biopsy-supported diagnoses or specialist assessments that clearly identify the right cornea as the site. Check documentation if laterality or primary site is unclear.
Do not use for
Do not use it for benign corneal lesions, unspecified eye site, or malignant disease in the left cornea or another ocular structure. If the record does not clearly state malignancy, check documentation.
Coding tip
Verify both laterality and anatomic site in the note before assigning C69.11.
