ICD-10 Code H54.52A2 – Low vision left eye category 2, normal vision right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.52A2 – Low vision left eye category 2, normal vision right eye
What it is
This code identifies low vision in the left eye at category 2, while the right eye has normal vision. Use it when documentation specifies this laterality and severity.
Clinical signs
Clinical findings usually show reduced visual function in the left eye with preserved normal vision in the right eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents low vision limited to the left eye and states category 2 severity. It is appropriate for ophthalmology or optometry notes that clearly distinguish each eye’s vision status. Check documentation if laterality or category is not explicit.
Do not use for
Do not use this code if both eyes are affected, if the right eye is not normal, or if the record only says “vision loss” without category detail. Do not guess the severity.
Coding tip
Verify the eye laterality and low-vision category in the assessment before assigning H54.52A2.
