Blindness left eye category 3, normal vision right eye

This code signifies complete or near-complete vision loss in the left eye, classified as category 3 blindness (e.g., visual acuity worse than 20/400 or visual field less than 10 degrees from fixation), while the right eye maintains normal visual acuity. It describes a unilateral severe visual impairment with the contralateral eye unaffected.

Apply this code when documentation clearly indicates profound blindness in the left eye, meeting the criteria for category 3 impairment, and explicitly states that the right eye has normal vision. This is typically used for patients undergoing evaluation or management for their unilateral severe vision loss.

• Ensure the documentation specifies "left eye" and confirms "normal vision right eye" to accurately assign this code.
• Verify the level of blindness (category 3) is explicitly stated or can be inferred from the documented visual acuity or visual field measurements.
• Do not confuse with codes for low vision or other categories of blindness; this code is specific to category 3 blindness in the left eye with normal vision in the right.
