ICD-10 Code H47.021 – Hemorrhage in optic nerve sheath, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.021 – Hemorrhage in optic nerve sheath, right eye
What it is
This code identifies bleeding within the optic nerve sheath on the right side. Use it when the documentation specifically states hemorrhage in the right optic nerve sheath.
Clinical signs
Clinical features vary; refer to documentation. Findings may include optic nerve-related visual disturbance or exam evidence of hemorrhage around the right optic nerve sheath.
When to use this code
Use H47.021 when the provider documents hemorrhage in the optic nerve sheath of the right eye. It is appropriate for ophthalmology, neurology, or imaging-based diagnoses that clearly localize the bleeding to the right side.
If the note only mentions optic nerve abnormality without hemorrhage or laterality, check documentation before coding. Code the documented condition exactly as stated.
Do not use for
Do not use this code for unspecified optic nerve sheath hemorrhage or for left-eye or bilateral involvement. Do not assign it for other optic nerve disorders without documented hemorrhage.
Coding tip
Verify both the hemorrhage and the right-eye laterality in the record before assigning H47.021.
