Low vision r eye category 1, blindness left eye category 4

This code signifies a patient presenting with low vision in their right eye, classified as category 1, and more severe vision impairment in their left eye, classified as category 4 blindness. This indicates a significant disparity in visual acuity between the two eyes, with the left eye experiencing profound vision loss.

Use this code when documentation clearly specifies low vision in the right eye (e.g., best-corrected visual acuity between 20/70 and 20/200) and blindness in the left eye (e.g., best-corrected visual acuity worse than 20/400 or visual field constricted to 10 degrees or less). This code is appropriate for reporting the specific visual impairment levels in each eye as determined by an ophthalmologist or optometrist.

• Ensure the medical record explicitly states the visual acuity or visual field measurements for each eye to support the specific categories.
• Do not confuse with codes for unspecified low vision or blindness, or codes where the vision impairment is symmetrical.
• Always sequence this code after the underlying cause of the low vision and blindness, if known (e.g., diabetic retinopathy, glaucoma).
