Unspecified keratitis

This code signifies inflammation of the cornea where the specific cause or type of inflammation has not been identified by the clinician. It represents a general diagnosis of corneal inflammation without further etiological or morphological detail.

Use this code when the medical record clearly indicates keratitis but lacks documentation specifying the infectious agent (e.g., bacterial, viral, fungal), the inflammatory process (e.g., ulcerative, punctate), or the underlying cause. This is often an interim diagnosis or used when diagnostic workup is incomplete or inconclusive.

• Avoid using this code if more specific documentation regarding the type or cause of keratitis is available (e.g., H16.0- for corneal ulcer, H16.1- for other superficial keratitis).
• Always query the provider for more specific information if possible, as a more precise diagnosis can impact treatment and reimbursement.
• Ensure the documentation supports the "unspecified" nature; if a specific type of keratitis is ruled out, but no other is identified, this code may be appropriate.
