Sudden visual loss, right eye

This code describes the acute onset of partial or complete vision loss in the patient's right eye. This condition is typically characterized by a rapid decrease in visual acuity, often occurring within minutes to hours. It signifies an urgent ophthalmological concern requiring prompt evaluation.

Use this code when documentation clearly indicates a sudden, unexplained decrease in vision specifically affecting the right eye. Supporting documentation should include the patient's history of present illness detailing the acute onset of visual disturbance and findings from an ophthalmological examination confirming the right eye involvement.

• Ensure laterality is explicitly documented as "right eye" to support this specific code.
• Distinguish from gradual vision loss or chronic conditions; "sudden" is key for this code.
• Always look for an underlying cause (e.g., retinal artery occlusion, optic neuropathy) and code it as a primary diagnosis if identified and supported by documentation.
