Low vision right eye category 1, normal vision left eye

This code signifies a patient experiencing low vision in their right eye, classified as category 1 (moderate visual impairment), while their left eye maintains normal visual acuity. This unilateral impairment indicates a significant difference in visual function between the two eyes.

Use this code when documentation clearly states low vision category 1 in the right eye and normal vision in the left eye, often following a comprehensive ophthalmological examination. This is appropriate for patients whose best-corrected visual acuity in the right eye falls within the range for category 1 low vision (e.g., 20/70 to 20/200), and the left eye is 20/20 or better.

• Ensure the laterality (right eye) and the specific low vision category (category 1) are explicitly documented.
• Do not use this code if both eyes have low vision or if the left eye also has any degree of visual impairment.
• Always sequence this code after the underlying cause of the low vision, if known and documented.
