ICD-10 Code H47.319 – Coloboma of Optic Disc, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.319 – Coloboma of optic disc, unspecified eye
What it is
H47.319 identifies a congenital defect of the optic disc in which part of the disc is missing or excavated. Use it when the record states optic disc coloboma but does not specify the eye.
Clinical signs
Findings may include an abnormally large, pale, or excavated optic disc on eye examination. Visual acuity or field defects may be present, but clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents coloboma of the optic disc and laterality is not stated. It also fits notes describing a congenital optic disc coloboma without additional qualifying details. If the chart names a different ocular coloboma site, check documentation.
Do not use for
Do not use H47.319 for coloboma of the iris, lens, retina, or choroid. Do not assign it when the record specifies a different eye or when the finding is only a suspected optic nerve anomaly.
Coding tip
Confirm whether the provider documented the eye involved; if not, H47.319 is the unspecified-eye option.
