ICD-10 Code H47.399 – Other disorders of optic disc, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.399 – Other disorders of optic disc, unspecified eye
What it is
This code identifies a documented disorder of the optic disc when the eye is not specified. Use it for optic disc abnormalities that do not fit a more specific diagnosis. Check documentation.
Clinical signs
Findings may include optic disc swelling, pallor, cupping, or other abnormal disc appearance on exam. Clinical features vary; refer to documentation.
When to use this code
Use H47.399 when the clinician documents an optic disc disorder but does not identify the affected eye. It also fits cases where the record describes an optic disc abnormality without a more precise subtype. Code only what is documented.
Do not use for
Do not use this code for a clearly specified optic disc disorder or when the affected eye is documented elsewhere. Avoid it if the note supports a different optic nerve or retinal diagnosis.
Coding tip
Before assigning H47.399, confirm that the record supports an optic disc disorder and that laterality is truly unspecified.
