Coloboma of optic disc, right eye

This code describes a congenital anomaly of the optic disc in the right eye, characterized by a localized excavation or defect due to incomplete closure of the embryonic fissure. This malformation can affect visual acuity and may be associated with other ocular or systemic abnormalities.

Use this code when documentation specifies a coloboma of the optic disc affecting the right eye. This diagnosis is typically made during an ophthalmologic examination and may be supported by findings from fundoscopy, optical coherence tomography (OCT), or other imaging studies.

• Ensure laterality is clearly documented; differentiate from left eye (H47.312) or bilateral (H47.313).
• Do not confuse with optic nerve hypoplasia or optic atrophy, which are distinct conditions.
• Code any associated visual disturbances or other ocular conditions separately.
