Corneal ulcer with hypopyon, left eye

This code signifies an ulcerative lesion on the cornea of the left eye, accompanied by hypopyon. Hypopyon is a collection of white blood cells in the anterior chamber of the eye, indicating significant inflammation or infection. This condition is often severe and can lead to vision loss if not promptly treated.

This code is appropriate when documentation clearly specifies a corneal ulcer affecting the left eye, with the presence of hypopyon. Supporting documentation would include ophthalmologist notes detailing slit-lamp examination findings, laterality, and the observation of a purulent exudate in the anterior chamber.

• Ensure documentation explicitly states "hypopyon" in conjunction with the corneal ulcer; otherwise, a different corneal ulcer code without hypopyon may be more appropriate.
• Verify laterality (left eye) is clearly documented. If the ulcer is in the right eye or bilateral, a different code should be selected.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter, followed by any underlying infectious agents if identified.
