ICD-10 Code H54.51 – Low vision, right eye, normal vision left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.51 – Low vision, right eye, normal vision left eye
What it is
This code identifies reduced vision in the right eye while the left eye has normal vision. Use it when the record clearly documents unilateral low vision affecting the right eye only.
Clinical signs
Clinical features vary; refer to documentation. Typical records note decreased visual acuity or impaired visual function in the right eye, with normal vision in the left eye.
When to use this code
Use this code when the provider documents low vision limited to the right eye and states the left eye is normal. It is appropriate for ophthalmology or vision-assessment notes that specify unilateral impairment. Check documentation if laterality or degree of vision loss is unclear.
Do not use for
Do not use it when both eyes have reduced vision or when the chart does not specify the right eye. Do not assign it for unspecified visual loss; check documentation.
Coding tip
Verify laterality and the documented status of the left eye before you code.
