H16.40 - Unspecified corneal neovascularization
| ICD-10: | H16.40 |
| Short Description: | Unspecified corneal neovascularization |
| Long Description: | Unspecified corneal neovascularization |
| Status: | Not Valid for Submission |
| Version: | ICD-10-CM 2022 |
| Code Classification: |
H16.40 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of unspecified corneal neovascularization. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.
Unspecified diagnosis codes like H16.40 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.
Specific Coding for Unspecified corneal neovascularization
Non-specific codes like H16.40 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for unspecified corneal neovascularization:
- BILLABLE CODE - Use H16.401 for Unspecified corneal neovascularization, right eye
- BILLABLE CODE - Use H16.402 for Unspecified corneal neovascularization, left eye
- BILLABLE CODE - Use H16.403 for Unspecified corneal neovascularization, bilateral
- BILLABLE CODE - Use H16.409 for Unspecified corneal neovascularization, unspecified eye

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.
