Central corneal ulcer, right eye

This code signifies an ulcerative lesion located in the central portion of the cornea of the right eye. This condition involves a break in the corneal epithelium and can extend into the corneal stroma, often leading to significant vision impairment. It is typically caused by infection (bacterial, viral, fungal, or parasitic) or severe dry eye.

Apply this code when documentation clearly indicates a corneal ulcer affecting the central part of the right eye. This diagnosis is supported by ophthalmological examination findings such as a visible corneal defect, stromal infiltration, and often associated with pain, photophobia, and decreased visual acuity.

• Ensure laterality is accurately documented and selected; this code is specific to the right eye.
• Distinguish from peripheral corneal ulcers (H16.02-) and other corneal disorders like keratitis without ulceration.
• Always look for an underlying cause (e.g., infectious agent) to code secondary diagnoses if identified.
