H16.009 is a billable ICD-10 code used to specify a medical diagnosis of unspecified corneal ulcer, unspecified eye. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like H16.009 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Bacterial corneal ulcer
- Corneal erosion
- Corneal non-healing epithelial ulcer
- Corneal ulcer
- Corneal ulcer caused by Acanthamoeba
- Corneal ulcer due to vitamin A deficiency
- Dystrophic corneal ulcer
- Infective corneal ulcer
- Inflammatory corneal ulcer
- Limbal guttering
- Limbal guttering with ulceration
- Neuropathic corneal ulcer
- Protozoal corneal ulcer
- Serpiginous ulcer
- Viral corneal ulcer
- Corneal Ulcer-. loss of epithelial tissue from the surface of the cornea due to progressive erosion and necrosis of the tissue; usually caused by bacterial, fungal, or viral infection.

Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.
Problems with the cornea include:
- Refractive errors
- Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material
Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.
