Coloboma of optic disc, unspecified eye

This code describes a congenital anomaly characterized by a localized defect or notch in the optic disc, resulting from incomplete closure of the embryonic fissure. This malformation can affect the optic nerve head, often appearing as an excavation or pit, and may be associated with visual field defects.

Use this code when documentation specifies a coloboma of the optic disc without further detail regarding the affected eye (e.g., "coloboma of optic disc noted"). This code is appropriate when the laterality is not specified in the clinical record.

• Always seek clarification from the provider if laterality (right, left, or bilateral) is not documented, as more specific codes exist.
• Do not confuse optic disc coloboma with optic nerve hypoplasia or optic atrophy, which are distinct conditions.
• Review the patient's history for any associated ocular or systemic anomalies, as colobomas can be part of broader syndromes.
