ICD-10: H55.09

ICD-10 code H55.09 refers to "Other forms of nystagmus," which is categorized under the broader classification of nystagmus and other irregular eye movements. This code is used in clinical settings to document and bill for conditions that involve abnormal eye movements not classified under more specific types of nystagmus.

Understanding Nystagmus

Nystagmus is characterized by involuntary, repetitive eye movements that can affect vision and balance. These movements can be horizontal, vertical, or rotary, and they may occur in various patterns. Nystagmus can be congenital (present at birth) or acquired later in life due to various factors, including neurological disorders, inner ear problems, or certain medications.

Types of Nystagmus

1. Congenital Nystagmus: Often present from birth, this type typically stabilizes in early childhood and may not significantly impair vision.
2. Acquired Nystagmus: This form develops later in life and can be associated with various medical conditions, including:
   - Neurological disorders (e.g., multiple sclerosis)
   - Inner ear diseases (e.g., vestibular disorders)
   - Alcohol or drug intoxication
   - Certain medications

Clinical Presentation

Patients with nystagmus may experience symptoms such as:
- Blurred or fluctuating vision
