Corneal staphyloma, right eye

This code signifies a corneal staphyloma affecting the right eye. A corneal staphyloma is an ectasia (bulging) of the cornea, often lined with uveal tissue, resulting from thinning and weakening of the corneal layers, typically due to inflammation or trauma. This protrusion can lead to significant visual impairment and discomfort.

Use this code when documentation clearly indicates a diagnosis of corneal staphyloma specifically in the right eye. Supporting documentation would include ophthalmological examination findings detailing the location, size, and characteristics of the staphyloma, often confirmed by imaging such as anterior segment OCT.

• Ensure laterality is precisely documented; do not use this code if the staphyloma is in the left or both eyes.
• Distinguish from corneal ectasia without uveal involvement, which may be coded differently (e.g., keratoconus).
• Code any underlying cause of the staphyloma (e.g., corneal ulcer, trauma) as an additional diagnosis, following sequencing guidelines.
