Unspecified superficial keratitis, left eye

This code signifies inflammation of the superficial layers of the cornea in the left eye, where the specific type or cause of the keratitis is not documented. It indicates a general corneal surface inflammation without further diagnostic specificity.

Use this code when the physician's documentation clearly states "superficial keratitis, left eye" but does not specify the etiology (e.g., punctate, filamentary, bacterial, viral). This code is appropriate when the exact nature of the corneal inflammation is unknown or not yet determined.

• Avoid using this code if a more specific type of superficial keratitis (e.g., H16.112 for punctate keratitis, left eye) is documented.
• Always review the entire encounter note for any clues that might lead to a more specific diagnosis.
• Query the provider if the documentation is ambiguous and a more precise diagnosis could be obtained.
