Blindness right eye category 5, normal vision left eye

This code signifies a severe visual impairment in the right eye, classified as "category 5" blindness according to the World Health Organization (WHO) visual impairment scale, while the left eye maintains normal visual acuity. Category 5 blindness typically corresponds to no light perception or light perception only.

This code is appropriate for patients diagnosed with profound vision loss in their right eye, where the left eye's vision is unimpaired. Documentation must clearly specify the laterality of the blindness and confirm normal vision in the contralateral eye, often supported by Snellen chart readings or other visual acuity assessments.

• Ensure the documentation explicitly states "right eye" blindness and "normal vision left eye" to support this specific laterality.
• Do not confuse with codes for partial blindness or blindness in both eyes; this code is for unilateral, severe right eye blindness with a normal left eye.
• 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.
