Unspecified corneal neovascularization, right eye

This code represents the presence of new, abnormal blood vessel growth in the cornea of the right eye, where the specific type or cause of the neovascularization is not documented. Corneal neovascularization can impair vision and is often a response to chronic inflammation, infection, or hypoxia.

Use this code when documentation indicates corneal neovascularization in the right eye, but the ophthalmologist has not specified the underlying cause or a more precise type (e.g., ghost vessels, pannus). This code is appropriate when the medical record lacks the detail to assign a more specific code within the H16.4 subcategory.

• Always attempt to query for a more specific type of corneal neovascularization if possible, as more detailed codes exist (e.g., H16.41- for ghost vessels).
• Ensure laterality is clearly documented as "right eye" to support this specific code.
• If the cause of the neovascularization is known and documented, code the underlying condition first, if applicable, and then the corneal neovascularization.
