Central corneal ulcer, unspecified eye

This code signifies an inflammatory lesion of the central cornea, characterized by tissue loss and often associated with infection. It represents a defect in the corneal epithelium and stroma, located in the central visual axis, without specifying the affected eye.

Apply this code when documentation indicates a central corneal ulcer but does not specify whether it affects the right or left eye. This is appropriate for initial encounters where laterality is undetermined or when the medical record explicitly states "unspecified eye."

• Avoid using this code if laterality (right or left eye) is documented; instead, choose the more specific H16.011 or H16.012.
• Always query the provider for laterality if not specified, as more specific codes are preferred for accurate data collection and reimbursement.
• Consider additional codes for the underlying cause of the ulcer (e.g., bacterial, fungal, viral) if identified and documented.
