ICD-10 Code H54.0X43 – Blindness right eye category 4, blindness left eye category 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.0X43 – Blindness right eye category 4, blindness left eye category 3
What it is
This code identifies severe visual loss in both eyes, with the right eye classified as blindness category 4 and the left eye as blindness category 3. Use it when documentation specifies these bilateral vision categories.
Clinical signs
Clinical features vary; refer to documentation. Records may describe profound visual impairment, limited ability to perceive detail, and major functional restriction from reduced binocular vision.
When to use this code
Use this code when the provider documents blindness category 4 in the right eye and category 3 in the left eye. It is appropriate for ophthalmology, vision rehabilitation, or problem-list documentation that states these exact categories. Check documentation if laterality or category is unclear.
Do not use for
Do not use it if the record only says low vision, unspecified blindness, or a different category combination. If the documentation does not clearly identify both eyes and their categories, check documentation.
Coding tip
Verify the eye-specific categories separately before assigning H54.0X43.
