ICD-10 Code H47.093 – Other disorders of optic nerve, not elsewhere classified, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.093 – Other disorders of optic nerve, not elsewhere classified, bilateral
What it is
H47.093 identifies a bilateral optic nerve disorder that does not fit a more specific ICD-10 category. Use it when documentation confirms both optic nerves are affected and the diagnosis remains nonspecific.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced visual acuity, visual field defects, or abnormal optic nerve appearance on exam or imaging.
When to use this code
Use this code when the provider documents an unspecified or other optic nerve disorder involving both eyes. It is appropriate when the record supports bilateral optic nerve involvement but does not name a more specific diagnosis. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for unilateral optic nerve disorders or for conditions with a more specific ICD-10 diagnosis. If the chart describes glaucoma, optic neuritis, or another named disorder, code that condition instead.
Coding tip
Verify that the documentation states bilateral involvement; laterality drives the code choice here.
