Valid for Submission
H55.00 is a billable diagnosis code used to specify a medical diagnosis of unspecified nystagmus. The code H55.00 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H55.00 might also be used to specify conditions or terms like acquired nystagmus, essential tremor, eyelid nystagmus, hereditary essential tremor, idiopathic nystagmus , irregular nystagmus, etc.
Unspecified diagnosis codes like H55.00 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

- NYSTAGMUS PATHOLOGIC-. involuntary movements of the eye that are divided into two types jerk and pendular. jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction and is usually caused by central or peripheral vestibular dysfunction. pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. adams et al. principles of neurology 6th ed p272
- NYSTAGMUS PHYSIOLOGIC-. involuntary rhythmical movements of the eyes in the normal person. these can be naturally occurring as in end position end point end stage or deviational nystagmus or induced by the optokinetic drum nystagmus optokinetic caloric test or a rotating chair.
- NYSTAGMUS OPTOKINETIC-. normal nystagmus produced by looking at objects moving across the field of vision.
- NYSTAGMUS CONGENITAL-. nystagmus present at birth or caused by lesions sustained in utero or at the time of birth. it is usually pendular and is associated with albinism and conditions characterized by early loss of central vision. inheritance patterns may be x linked autosomal dominant or recessive. adams et al. principles of neurology 6th ed p275

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.
