Corneal abscess, right eye

This code signifies a localized collection of pus within the corneal stroma of the right eye, typically caused by bacterial, fungal, or protozoal infection. It represents a severe and potentially sight-threatening inflammatory condition of the cornea.

Apply this code when documentation clearly indicates a diagnosis of corneal abscess affecting the right eye. Supporting documentation would include ophthalmological examination findings such as a white or yellowish infiltrate in the cornea, associated with pain, photophobia, and reduced vision.

• Always specify laterality (right, left, bilateral, or unspecified) for corneal conditions.
• Distinguish from corneal ulcer (H16.0-) which may or may not involve an abscess.
• Code any underlying infectious organism (e.g., B95-B97) as an additional diagnosis if identified.
