Punctate keratitis, right eye

This code signifies an inflammatory condition of the cornea characterized by scattered, pinpoint lesions or erosions on the corneal surface of the right eye. These lesions are typically visible upon slit lamp examination and can be caused by various factors, including viral infections, dry eye, or medication toxicity.

Apply this code when documentation specifies punctate keratitis affecting the right eye. This diagnosis is often supported by ophthalmological examination findings detailing corneal epithelial defects or staining patterns consistent with punctate lesions in the specified eye.

• Ensure laterality is clearly documented as right eye; separate codes exist for left and bilateral involvement.
• Distinguish from other forms of keratitis, such as ulcerative or interstitial, which have different ICD-10-CM codes.
• Look for underlying causes (e.g., viral conjunctivitis, dry eye syndrome) that may require additional coding.
