Blindness r eye category 4, low vision left eye category 2

This code signifies a patient presenting with complete blindness in their right eye, classified as category 4 visual impairment. Concurrently, the left eye exhibits low vision, specifically categorized as category 2 visual impairment. This bilateral condition indicates a significant disparity in visual acuity between the two eyes.

Apply this code when documentation clearly states blindness in the right eye (e.g., no light perception, NLP) and low vision in the left eye, with specific Snellen or equivalent acuity measurements supporting category 2. This is appropriate for patients with permanent, non-correctable vision loss meeting these criteria.

• Ensure the documentation specifies which eye is blind and which has low vision, along with the respective categories.
• Do not use this code if the visual impairment categories are different for either eye or if only one eye is affected.
• Verify the laterality is correctly assigned; H54.1142 is specific to right eye blindness and left eye low vision.
