Frequently Asked Questions

What are the common causes of corneal neovascularization?

Common causes include chronic inflammation, infection, and hypoxia due to contact lens wear or other ocular surface diseases.

How is corneal neovascularization treated?

Treatment options may include managing underlying conditions, using anti-VEGF injections, or surgical interventions such as corneal transplantation in severe cases.

Is H16.40 used for all types of corneal neovascularization?

H16.40 is used when the specific type of corneal neovascularization is not specified. If the type is known, a more specific code should be used.
