ICD-10 Code H54.4 – Blindness, one eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.4 – Blindness, one eye
What it is
H54.4 identifies blindness in one eye, meaning vision is absent or functionally absent in a single eye. Use it when the record clearly documents unilateral blindness.
Clinical signs
Findings may include no light perception, severe visual loss, or longstanding loss of vision in one eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents blindness affecting only one eye and does not specify a more detailed cause code. It may apply to congenital or acquired unilateral blindness if the note supports the diagnosis. Confirm laterality and whether the other eye has normal or reduced vision.
Do not use for
Do not use H54.4 for partial vision loss, low vision, or bilateral blindness. If the record identifies a specific underlying disorder or injury, code that condition as directed by documentation.
Coding tip
Check whether the chart states blindness, visual impairment, or another eye disorder, because the wording determines whether H54.4 is appropriate.
