ICD-10 Code H54.50 – Low vision, one eye, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.50 – Low vision, one eye, unspecified eye
What it is
This code identifies reduced vision in one eye when the affected eye is not specified. Use it for documented low vision that does not meet blindness criteria and is limited to one eye.
Clinical signs
Patients may report blurred vision, difficulty reading, or trouble recognizing faces in one eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states low vision in one eye but does not name the right or left eye. It also fits when the provider documents unilateral low vision without further detail. If the note specifies the eye, code the laterality instead.
Do not use for
Do not use this code for blindness, normal vision, or low vision affecting both eyes. Do not guess the eye when the documentation is unclear; check documentation.
Coding tip
Confirm laterality in the ophthalmology note before assigning H54.50.
