ICD-10 Code H54.0X4 – Blindness right eye, category 4 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.0X4 – Blindness right eye, category 4
What it is
This code identifies severe visual loss in the right eye, classified as blindness category 4. Use it when documentation specifies the right eye and the level of impairment matches this category.
Clinical signs
Clinical features vary; refer to documentation. Records may note profound loss of vision in the right eye, including inability to perceive useful vision, with the left eye status documented separately.
When to use this code
Use H54.0X4 when the provider documents blindness in the right eye and specifies category 4. It is appropriate for ophthalmology notes, problem lists, and claims when the diagnosis is clearly stated. Do not infer laterality or severity from vague wording; check documentation.
Do not use for
Do not use this code for unspecified visual loss, low vision, or blindness in both eyes. If the record does not confirm the right eye and category 4, check documentation.
Coding tip
Confirm both laterality and severity before assigning H54.0X4; incomplete eye documentation often requires a different code.
