ICD-10 Code H47.391 – Other disorders of optic disc, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.391 – Other disorders of optic disc, right eye
What it is
This code identifies a disorder of the optic disc in the right eye that does not fit a more specific diagnosis. Use it when documentation states an unspecified or other optic disc abnormality limited to the right eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include optic disc abnormality on eye examination, such as swelling, pallor, or other structural change, but the record should support the right-eye location.
When to use this code
Use H47.391 when the clinician documents an optic disc disorder in the right eye and no more specific code applies. It is appropriate for ophthalmology or neurology notes that describe an atypical optic disc finding without a clearer diagnosis. Check documentation if the laterality or exact condition is unclear.
Do not use for
Do not use this code for optic disc disorders of the left eye, bilateral disease, or a more specific optic nerve or retinal diagnosis. If the note names a definite condition, code that condition instead.
Coding tip
Always verify laterality and whether the provider used “other” because a more specific optic disc code was not documented.
