Punctate keratitis, unspecified eye

This code signifies an inflammatory condition of the cornea characterized by multiple, discrete, small lesions or erosions on its surface. These lesions are typically superficial and can be caused by various factors, including viral infections, dry eye, or exposure to irritants. The "unspecified eye" designation indicates that the laterality of the condition is not documented.

Apply this code when the medical record clearly documents punctate keratitis without specifying whether it affects the right, left, or both eyes. This is appropriate when the physician's diagnosis is "punctate keratitis" and no further laterality information is provided.

• Avoid using this code if laterality (right, left, or bilateral) is documented; instead, use the more specific codes (H16.141, H16.142, H16.143).
• Ensure the documentation supports the "punctate" nature of the keratitis, distinguishing it from other forms of keratitis.
• Always query the provider for laterality if it's missing, as a more specific code may be available.
