Blindness r eye category 3, blindness left eye category 4

This code signifies a severe visual impairment where the right eye is classified as having blindness category 3 and the left eye as having blindness category 4. This indicates a significant difference in the degree of vision loss between the two eyes, with the left eye experiencing a more profound level of blindness according to the WHO classification of visual impairment.

This code is appropriate for patients diagnosed with bilateral blindness where the specific categories of visual impairment for each eye are documented as category 3 for the right eye and category 4 for the left eye. Documentation must clearly specify the laterality and the corresponding WHO blindness category for each eye, often based on visual acuity measurements and visual field assessments.

• Ensure the medical record explicitly states "blindness category 3" for the right eye and "blindness category 4" for the left eye, not just general terms like "severe vision loss."
• Do not confuse with codes for unilateral blindness or codes where the blindness categories for each eye are different from 3 and 4.
• Always review the provider's documentation for the specific WHO blindness category assigned to each eye to ensure accurate code selection.
