Blindness r eye category 4, blindness left eye category 5

This code signifies severe visual impairment in the right eye, classified as category 4 blindness, coupled with profound visual impairment in the left eye, classified as category 5 blindness. This indicates a significant bilateral visual deficit, with the left eye having even less functional vision than the right.

Apply this code when documentation clearly specifies the World Health Organization (WHO) visual impairment categories for both eyes. This is appropriate for patients with conditions such as advanced glaucoma, diabetic retinopathy, or macular degeneration that have progressed to these specific levels of bilateral blindness. Documentation should include visual acuity measurements and/or ophthalmologist's assessment explicitly stating the category of blindness for each eye.

• Ensure the laterality (right vs. left eye) and the specific blindness categories (4 and 5) are clearly documented for accurate code assignment.
• Do not confuse with codes for low vision or less severe categories of blindness; this code is specific to categories 4 and 5.
• Always sequence this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting care.
