ICD-10 Code H54.413A – Blindness right eye category 3, normal vision left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H54.413A – Blindness right eye category 3, normal vision left eye
What it is
This code identifies severe vision loss in the right eye, with normal vision in the left eye. It is used when the right eye meets category 3 blindness criteria and the opposite eye is not impaired.
Clinical signs
Documented findings usually show profound vision loss or no useful vision in the right eye. The left eye should be described as having normal vision; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents blindness in the right eye at category 3 and normal vision in the left eye. It may apply after ophthalmic examination, visual acuity testing, or specialist assessment confirms the laterality and severity. You should code from the provider’s recorded diagnosis, not infer from symptoms alone.
Do not use for
Do not use this code for partial vision loss, bilateral blindness, or unspecified visual impairment. If the record does not clearly state right-eye category 3 blindness with normal left-eye vision, check documentation.
Coding tip
Verify laterality and the documented vision category before assigning H54.413A.
