ICD-10 Code H55.03 – Visual deprivation nystagmus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H55.03 – Visual deprivation nystagmus
What it is
Visual deprivation nystagmus is an involuntary rhythmic eye movement that develops when normal visual input is reduced or absent. Use this code for the documented diagnosis, not for nonspecific eye shaking.
Clinical signs
Typical findings include repetitive, uncontrolled ocular oscillation and reduced visual fixation. Clinical features vary; refer to documentation.
When to use this code
Use H55.03 when the record specifically identifies visual deprivation nystagmus, including cases linked to impaired visual input such as severe media opacity or other deprivation states. Code it when the provider documents the condition as the diagnosis. Check documentation if the note only describes nystagmus without cause.
Do not use for
Do not use this code for other nystagmus types, such as congenital, vestibular, or unspecified nystagmus. Do not assign it when visual deprivation is not documented.
Coding tip
Match the code to the provider’s stated nystagmus type and avoid assuming deprivation as the cause.
