Glare sensitivity

This code describes photophobia, an abnormal intolerance to visual light that causes discomfort or pain. It is a symptom, not a disease, and can range from mild annoyance to severe pain, often leading to squinting, blinking, or eye closure.

Use this code when documentation explicitly states "glare sensitivity" or "photophobia" as a presenting symptom or a diagnosed condition. This code is appropriate when the patient experiences discomfort or pain in response to light, regardless of the underlying cause.

• Always code the underlying cause of the glare sensitivity if known and documented (e.g., migraine, conjunctivitis, corneal abrasion).
• Do not confuse with visual discomfort from bright lights without pain or true photophobia.
• This code can be a primary or secondary diagnosis depending on the clinical scenario and whether an underlying cause is identified.
