ICD-10 Code H54.62 – Unqualified Visual Loss, Left Eye, Normal Vision Right Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.62 – Unqualified visual loss, left eye, normal vision right eye
What it is
This code identifies visual loss in the left eye when the right eye has normal vision. It does not specify the cause or degree of impairment, only the laterality and the fact that the opposite eye is normal.
Clinical signs
Clinical features vary; refer to documentation. You may see reduced visual acuity or reported blindness in the left eye, with preserved normal vision in the right eye.
When to use this code
Use this code when the record clearly states unqualified visual loss in the left eye and normal vision in the right eye. It is appropriate when the provider does not document a more specific diagnosis, such as low vision, blindness category, or an underlying eye disorder.
Do not use for
Do not use it if the documentation specifies a different eye, bilateral visual loss, or a more detailed visual impairment code. Check documentation if the cause, severity, or laterality is unclear.
Coding tip
Code only what is documented, and query for specificity if the note does not clearly confirm left-eye loss with normal right-eye vision.
