Macular keratitis, right eye

This code signifies an inflammatory condition affecting the macula of the cornea in the right eye. Macular keratitis is characterized by a dense, opaque corneal infiltrate that can significantly impair vision. It often results from bacterial, fungal, or viral infections.

Apply this code when documentation specifies macular keratitis affecting the right eye. This diagnosis is typically made during an ophthalmological examination, often supported by slit-lamp findings and potentially corneal cultures. Ensure the laterality (right eye) is clearly documented.

• Differentiate from other forms of keratitis (e.g., punctate, filamentous) by ensuring "macular" is explicitly stated.
• Always confirm laterality; separate codes exist for the left eye (H16.112) and bilateral involvement (H16.113).
• Look for an underlying cause (e.g., bacterial, viral, fungal infection) and code it as an additional diagnosis if identified and documented.
