ICD-10 Code H47.393 – Other disorders of optic disc, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.393 – Other disorders of optic disc, bilateral
What it is
H47.393 identifies a bilateral optic disc disorder that does not fit a more specific diagnosis. Use it when documentation describes abnormal optic discs in both eyes, but the exact cause is not stated.
Clinical signs
Findings may include optic disc swelling, pallor, or other disc abnormalities seen on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a nonspecific disorder of the optic disc affecting both eyes. It is appropriate when the record confirms bilateral disc involvement but does not support a more specific optic nerve or retinal diagnosis. Check documentation if the cause is unclear.
Do not use for
Do not use this code for unilateral optic disc disorders or for conditions with a more specific documented diagnosis. Do not assign it when the record only mentions suspected findings without confirmation.
Coding tip
Code the bilateral specificity only when the documentation clearly states both optic discs are involved.
