H47 is a non-billable ICD-10-CM category code for other disorders of optic [2nd] nerve and visual pathways, so it cannot be submitted on claims. Use a more specific code from this category instead, such as H47.011, H47.012, H47.013, and H47.019.

Patient EducationClinical

Optic Nerve Disorders

The optic nerve is a bundle of more than 1 million nerve fibers that carry visual messages. You have one connecting the back of each eye (your retina) to your brain. Damage to an optic nerve can cause vision loss. The type of vision loss and how severe it is depends on where the damage occurs. It may affect one or both eyes.

Questions About H47Overview

Is H47 (Other disorders of optic [2nd] nerve and visual pathways) a billable code?

No. This is a category header that groups the codes for other disorders of optic [2nd] nerve and visual pathways, and headers cannot be submitted on claims. Claims for other disorders of optic [2nd] nerve and visual pathways need a more specific code from this category, such as H47.011, H47.012, and H47.013.
