Code Classification

  • Diseases of the eye and adnexa
    (H00–H59)
    • Disorders of optic nerve and visual pathways
      (H46-H47)
      • Other disorders of optic [2nd] nerve and visual pathways
        (H47)

H47.4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of disorders of optic chiasm. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Disorders of optic chiasm

Non-specific codes like H47.4 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for disorders of optic chiasm:

  • Use H47.41 for Disorders of optic chiasm in (due to) inflammatory disorders - BILLABLE CODE

  • Use H47.42 for Disorders of optic chiasm in (due to) neoplasm - BILLABLE CODE

  • Use H47.43 for Disorders of optic chiasm in (due to) vascular disorders - BILLABLE CODE

  • Use H47.49 for Disorders of optic chiasm in (due to) other disorders - BILLABLE CODE

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:

  • Glaucoma is a group of diseases that are the leading cause of blindness in the United States. Glaucoma usually happens when the fluid pressure inside the eyes slowly rises and damages the optic nerve.
  • Optic neuritis is an inflammation of the optic nerve. Causes include infections and immune-related illnesses such as multiple sclerosis. Sometimes the cause is unknown.
  • Optic nerve atrophy is damage to the optic nerve. Causes include poor blood flow to the eye, disease, trauma, or exposure to toxic substances.
  • Optic nerve head drusen are pockets of protein and calcium salts that build up in the optic nerve over time

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.
