Blindness right eye category 4, normal vision left eye

This code signifies severe visual impairment, specifically blindness in the right eye, where the patient retains normal vision in the left eye. It indicates a significant unilateral visual deficit, impacting depth perception and overall visual field.

Apply this code when documentation clearly states "blindness" or "no light perception" in the right eye, while the left eye is noted as having "normal vision" or 20/20 acuity. This is appropriate for initial encounters for this specific visual impairment.

• Ensure documentation specifies "right eye" blindness and "normal vision" in the "left eye" to accurately assign this laterality.
• Verify the "category 4" classification of blindness is explicitly stated or can be inferred from the visual acuity (e.g., no light perception).
• Do not confuse with codes for low vision or other categories of blindness; this code is specific to category 4 blindness in the right eye with normal left eye vision.
