ICD-10-CM Code H51.8

Other specified disorders of binocular movement

Version 2020 Billable Code

Valid for Submission

H51.8 is a billable code used to specify a medical diagnosis of other specified disorders of binocular movement. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code H51.8 might also be used to specify conditions or terms like a pattern vergence, ablepharon, abnormal lateral conjugate gaze, abnormal vertical conjugate gaze, anomaly of divergence, associated movements on eye movement - finding, etc

Short Description:Other specified disorders of binocular movement

Information for Patients

Eye Movement Disorders

When you look at an object, you're using several muscles to move both eyes to focus on it. If you have a problem with the muscles, the eyes don't work properly.

There are many kinds of eye movement disorders. Two common ones are

  • Strabismus - a disorder in which the two eyes don't line up in the same direction. This results in "crossed eyes" or "walleye."
  • Nystagmus - fast, uncontrollable movements of the eyes, sometimes called "dancing eyes"

Some eye movement disorders are present at birth. Others develop over time and may be associated with other problems, such as injuries. Treatments include glasses, patches, eye muscle exercises, and surgery. There is no cure for some kinds of eye movement disorders, such as most kinds of nystagmus.
