Blindness r eye category 5, blindness left eye category 4

This code indicates severe visual impairment in both eyes, specifically blindness in the right eye (defined as no light perception or light perception with inaccurate projection) and severe low vision in the left eye (defined as visual acuity worse than 20/400 to 20/1000, or visual field less than 10 degrees but greater than 5 degrees). It describes a patient with significantly different levels of visual function between their two eyes.

Use this code for patients diagnosed with bilateral blindness where the right eye meets the criteria for Category 5 blindness and the left eye meets the criteria for Category 4 blindness, as per the ICD-10-CM classification of visual impairment. Documentation must clearly specify the visual acuity or visual field measurements for each eye, confirming these distinct categories of impairment.

• Ensure the documentation explicitly states the visual acuity or visual field for each eye to accurately assign the correct blindness category.
• Do not confuse with codes for unilateral blindness or codes where both eyes fall into the same blindness category.
• Always review the full ICD-10-CM visual impairment table to confirm the specific criteria for each category (0-9) before assigning.
