  • NON-BILLABLE CODE - H46.0 for Optic papillitis
  • BILLABLE CODE - Use H46.00 for Optic papillitis, unspecified eye
  • BILLABLE CODE - Use H46.01 for Optic papillitis, right eye
  • BILLABLE CODE - Use H46.02 for Optic papillitis, left eye
  • BILLABLE CODE - Use H46.03 for Optic papillitis, bilateral
  • NON-BILLABLE CODE - H46.1 for Retrobulbar neuritis
  • BILLABLE CODE - Use H46.10 for Retrobulbar neuritis, unspecified eye
  • BILLABLE CODE - Use H46.11 for Retrobulbar neuritis, right eye
  • BILLABLE CODE - Use H46.12 for Retrobulbar neuritis, left eye
  • BILLABLE CODE - Use H46.13 for Retrobulbar neuritis, bilateral
  • BILLABLE CODE - Use H46.2 for Nutritional optic neuropathy
  • BILLABLE CODE - Use H46.3 for Toxic optic neuropathy
  • BILLABLE CODE - Use H46.8 for Other optic neuritis
  • BILLABLE CODE - Use H46.9 for Unspecified optic neuritis

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code H46:


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Information for Patients


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.

There are many different types of optic nerve disorders, including:

Contact your health care provider if you are having vision problems. Tests for optic nerve disorders may include eye exams, ophthalmoscopy (an examination of the back of your eye), and imaging tests. Treatment depends on which disorder that you have. With some optic nerve disorders, you may get your vision back. With others, there is no treatment, or treatment may only prevent further vision loss.
