Other forms of nystagmus
Additional Information
Description
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
