ICD-10 Code H47.311 – Coloboma of optic disc, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.311 – Coloboma of optic disc, right eye
What it is
H47.311 identifies a congenital coloboma affecting the optic disc in the right eye. It means part of the optic nerve head did not form completely during eye development.
Clinical signs
Findings may include an abnormal optic disc appearance on eye exam and reduced or variable visual acuity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents coloboma of the optic disc in the right eye, with or without associated visual impairment. It is appropriate for confirmed congenital defects noted on ophthalmic examination or imaging. Do not assign it for nonspecific optic disc abnormalities without documentation of coloboma.
Do not use for
Do not use this code for coloboma of the left eye, both eyes, or unspecified eye. Check documentation if the record only mentions optic nerve anomaly or congenital eye defect without naming optic disc coloboma.
Coding tip
Verify laterality in the ophthalmology note before coding, because the right eye is specific to H47.311.
