What is a nystagmus test?

These nystagmus tests document and measure the inability of the eyes to maintain a static position as a result of peripheral, CNS (Central Nervous System) or congenital abnormality. The tests are conducted with the eyes open and closed and in “eyes forward” as well as “eyes right” and “eyes left” positions.

What is horizontal nystagmus?

Nystagmus is a condition where the eyes move rapidly and uncontrollably. They can move: side to side (horizontal nystagmus) up and down (vertical nystagmus) in a circle (rotary nystagmus)

What is Latent nystagmus?

Latent nystagmus is a binocular horizontal oscillation that becomesapparent when 1 eye is covered. First described by Faucon in 1872,8 latent nystagmus develops when congenital esotropiaprecludes frontal binocular vision early in infancy.

What is congenital nystagmus?

Abstract. Infantile nystagmus (IN), previously known as congenital nystagmus, is an involuntary to-and-fro movement of the eyes that persists throughout life. IN is one of three types of early-onset nystagmus that begin in infancy, alongside fusion maldevelopment nystagmus syndrome and spasmus nutans syndrome.

What causes nystagmus?

Nystagmus is caused by a miscommunication between the eye and the brain and affects the way our brains interpret movement signals from the eye. Nystagmus is typically caused by brain injuries and is a result of brain damage. This eye condition may be referred to as “dancing eyes” because of the repetitive eye movement.

What is nystagmus physiology?

Physiological nystagmus is a form of involuntary eye movement that is part of the vestibulo-ocular reflex (VOR), characterized by alternating smooth pursuit in one direction and saccadic movement in the other direction.

What is downbeat nystagmus?

Downbeat nystagmus (DBN) is the most common form of acquired involuntary ocular oscillations overriding fixation. It is characterised by slow upward drifts and fast downward phases.

What is the ICd-9 GEM?

The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

What is the ICd 10 code for vestibular dysfunction?

379.54 is a legacy non-billable code used to specify a medical diagnosis of nystagmus associated with disorders of the vestibular system. This code was replaced on September 30, 2015 by its ICD-10 equivalent.

What causes jerk nystagmus?

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.

What is eye movement?

A disorder characterized by involuntary movements of the eyeballs. Eye movement reflex stabilizing the retinal image of a visual stimulus to compensate for head or stimulus movement. Also, eye movement defects resulting from neurological, muscular, or genetic disorders.

Is H55.0 a reimbursement code?

Nystagmus. H55.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. The 2021 edition of ICD-10-CM H55.0 became effective on October 1, 2020. This is the American ICD-10-CM version of H55.0 - other international versions of ICD-10 H55.0 may differ.

What is the basic vestibular evaluation?

Basic vestibular evaluation, includes spontaneous nystagmus test with eccentric gaze fixation nystagmus, with recording, positional nystagmus test, minimum of 4 positions, with recording, optokinetic nystagmus test, bidirectional foveal and peripheral stimulation, with recording, and oscillating tracking test, with recording.

What is a spontaneous nystagmus test?

These nystagmus tests document and measure the inability of the eyes to maintain a static position as a result of peripheral , CNS (Central Nervous System) or congenital abnormality . The tests are conducted with the eyes open and closed and in “eyes forward” as well as “eyes right” and “eyes left” positions.

What is a sinusoidal axis rotational test?

This is a computerized test of the Vestibulo-Ocular Reflex (VOR), the neural mechanism that keeps a visual image registered on the fovea during head movement. It evaluates the three functional components of the VOR system: the peripheral end organ, the vestibular nuclei of the brain stem and the higher central vestibular connections. The test is accomplished by having the patient (with goggles on) move their head in both the horizontal and vertical plane at increasing velocities while the VOR system measures head velocity. From this data, the computer computes three characteristics of the VOR: gain (ratio of eye velocity to head velocity, phase (the number of degrees by which the eye “misses” the target), and asymmetry (a comparison of gain moving right with gain moving left). This information is useful for evaluating patients with balance disorders. Refer to article titled, “VAT Explanation & Justification.”
