ICD-10 Code H54.1142 – Blindness right eye category 4, low vision left eye category 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.1142 – Blindness right eye category 4, low vision left eye category 2
What it is
This code identifies severe visual impairment in both eyes: the right eye meets blindness category 4, while the left eye has low vision category 2. Use it when documentation specifies these eye-by-eye vision categories.
Clinical signs
Patients typically have marked loss of visual acuity and functional vision, with the degree differing between eyes. Clinical features vary; refer to documentation and the recorded vision categories.
When to use this code
Use this code when the provider documents blindness category 4 in the right eye and low vision category 2 in the left eye. It is appropriate for ophthalmology notes, problem lists, or assessments that clearly state both eye categories. Check documentation if the laterality or category is incomplete.
Do not use for
Do not use this code for unspecified visual loss, milder low vision, or blindness affecting only one eye. Do not assign it when the chart does not clearly document both eye categories.
Coding tip
Match the code to the exact eye-specific categories documented; if one eye’s category is missing, you need more documentation.
