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.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H47: its own notes plus those printed at Chapter 7. A note printed at a category, block or chapter applies to every code under it.

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury (trauma) of eye and orbit (S05.-)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71)

Notes

General instructions on how these codes are used.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes

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

What is the ICD-10 code for other disorders of optic [2nd] nerve and visual pathways?

H47 is the ICD-10-CM category for other disorders of optic [2nd] nerve and visual pathways, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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.
