Low vision r eye category 1, low vision left eye category 1

This code indicates bilateral low vision where the visual impairment in both the right and left eyes falls into category 1. Category 1 low vision is defined by a best-corrected visual acuity of less than 20/70 to 20/200, or a corresponding visual field loss to 20 degrees or less, but better than 10 degrees, in the better eye. It signifies a moderate level of visual impairment impacting daily activities.

Use this code when a patient presents with documented low vision in both eyes, and the ophthalmologist or optometrist has specifically categorized the impairment in each eye as category 1. This is typically supported by visual acuity measurements and/or visual field testing results that meet the criteria for category 1 low vision in both the right and left eyes.

• Ensure documentation clearly specifies the visual acuity or visual field for each eye and explicitly states "category 1" for both.
• Do not use this code if the low vision categories differ between the right and left eyes; a more specific code indicating different categories per eye would be appropriate.
• This code describes the level of low vision; always code the underlying cause of the low vision (e.g., macular degeneration, diabetic retinopathy) first.
