H16.409 is a billable diagnosis code used to specify a medical diagnosis of unspecified corneal neovascularization, unspecified eye. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
Unspecified diagnosis codes like H16.409 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.

Clinical Information
Corneal Neovascularization
new blood vessels originating from the corneal blood vessels and extending from the limbus into the adjacent corneal stroma. neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as trachoma, viral interstitial keratitis, microbial keratoconjunctivitis, and the immune response elicited by corneal transplantation.

Patient Education
Corneal Disorders
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
- Allergies
- Infections
- Injuries
- 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.
