ICD-10 Code H53.6 – Night blindness (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.6 – Night blindness
What it is
H53.6 identifies night blindness, or reduced vision in dim light. Use it when the chart documents difficulty seeing at night or poor dark adaptation.
Clinical signs
Common findings include trouble navigating in low light, delayed adjustment from bright to dark settings, and poor night driving vision. Clinical features vary; refer to documentation.
When to use this code
Use H53.6 when the provider specifically documents night blindness as the diagnosis or assessment. It may also fit when the record clearly describes nyctalopia or impaired dark adaptation without a more specific underlying eye disorder coded instead.
Do not use for
Do not use this code for general blurred vision, complete blindness, or vision loss caused by a documented condition with a more specific code. Check documentation if the cause is unclear.
Coding tip
Assign H53.6 only when the record supports night blindness as the reported problem, and code any identified underlying eye disease separately when instructed.
