Low vision left eye category 2, normal vision right eye

This code signifies a patient presenting with low vision in their left eye, classified as category 2, while their right eye maintains normal visual acuity. Low vision category 2 typically corresponds to moderate visual impairment, often defined by specific ranges of visual acuity or visual field loss. This condition impacts daily activities and may require assistive devices.

Use this code when documentation clearly indicates low vision category 2 in the left eye and normal vision in the right eye, as determined by an ophthalmologist or optometrist. This is applicable for patients undergoing vision rehabilitation, receiving prescriptions for low vision aids, or being evaluated for their visual impairment. Supporting documentation should include visual acuity measurements (e.g., Snellen chart results) and a clear statement of the low vision category.

• Ensure the documentation explicitly states "low vision category 2" for the left eye and "normal vision" for the right eye.
• Do not confuse this with other low vision categories (e.g., H54.51 for category 1) or codes for blindness.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting care.
