370.9
ICD-9-CMThis code represents inflammation of the cornea, the transparent front part of the eye, when the specific type or cause of the inflammation is not documented. It indicates a general diagnosis of corneal inflammation without further detail regarding its etiology or presentation.
Use this code when the medical record clearly states "keratitis" but lacks information about its specific type (e.g., bacterial, viral, fungal, ulcerative, punctate). It is appropriate when the provider has not yet determined or documented the precise nature of the corneal inflammation.
