ICD-10 Code H53.69 – Other Night Blindness (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.69 – Other night blindness
What it is
H53.69 identifies night blindness that is documented as other or unspecified in the record. Use it when the chart states impaired vision in low light, but does not name a more specific cause.
Clinical signs
Typical findings include difficulty seeing in dim light, trouble adapting from bright to dark environments, or reduced vision at dusk. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents night blindness, nyctalopia, or poor dark adaptation without a more specific diagnosis. It also fits when the cause is not yet established in the note. If the record names an underlying eye disease, code that condition instead when instructed.
Do not use for
Do not use H53.69 for general blurred vision, visual field loss, or decreased vision without low-light difficulty. Check documentation if the symptom is better explained by a specific retinal, corneal, or vitamin-related disorder.
Coding tip
Look for the exact wording “night blindness” or “nyctalopia” and code the more specific cause first if one is documented.
