2026 ICD-10-CM Diagnosis Code H54.121 – Low vision right eye category 1, blindness left eye
What it is
This code identifies reduced vision in the right eye at category 1 level, with blindness in the left eye. Use it when the record clearly documents this specific combination of visual impairment.
Clinical signs
Findings usually include limited visual acuity in the right eye and no functional vision in the left eye. Clinical features vary; refer to documentation.
When to use this code
Use H54.121 when the provider documents low vision category 1 in the right eye and blindness in the left eye. It is appropriate for ophthalmology notes, problem lists, or assessments that state this exact laterality and severity. Check documentation if the record uses different visual categories or does not specify both eyes.
Do not use for
Do not use this code for unspecified visual loss, bilateral low vision, or blindness affecting the opposite eye pattern. Check documentation if the diagnosis is less specific.
Coding tip
Code only when both eye laterality and severity are clearly documented; otherwise, query the provider.
