ICD-10 Code H47.023 – Hemorrhage in optic nerve sheath, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.023 – Hemorrhage in optic nerve sheath, bilateral
What it is
This code identifies bleeding within the optic nerve sheath affecting both eyes. Use it when documentation specifically states bilateral optic nerve sheath hemorrhage.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visual disturbance, optic disc changes, or imaging evidence of hemorrhage around both optic nerves.
When to use this code
Use H47.023 when the provider documents hemorrhage in the optic nerve sheath on both sides. It is appropriate for ophthalmology, neurology, or imaging reports that clearly localize the bleeding bilaterally.
If the record only mentions optic nerve bleeding without laterality, check documentation before coding. Assign the code only when bilateral involvement is explicit.
Do not use for
Do not use this code for retinal, vitreous, or intracranial hemorrhage. It is also not correct when the note does not confirm bilateral optic nerve sheath involvement.
Coding tip
Verify laterality and anatomic site in the source note; “optic nerve” alone is not enough for H47.023.
