ICD-10 Code H54.511A – Low vision right eye category 1, normal vision left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.511A – Low vision right eye category 1, normal vision left eye
What it is
This code identifies low vision in the right eye at category 1 severity, while the left eye has normal vision. Use it when documentation clearly distinguishes asymmetric visual impairment between the two eyes.
Clinical signs
Findings typically include reduced visual acuity in the right eye with preserved normal vision in the left eye. Clinical features vary; refer to documentation and the recorded eye-specific vision assessment.
When to use this code
Use this code when the provider documents category 1 low vision limited to the right eye and normal vision in the left eye. It is appropriate for ophthalmology or vision-loss assessments that specify laterality and severity. Check documentation if the record does not clearly state both eyes.
Do not use for
Do not use this code if low vision is bilateral, if the affected eye is different, or if the chart only says “poor vision” without eye-specific detail. Check documentation for the correct laterality and category.
Coding tip
Verify that the record supports both the right-eye category 1 loss and normal left-eye vision before assigning H54.511A.
