Unspecified corneal neovascularization, left eye

This code signifies the presence of new, abnormal blood vessel growth on the cornea of the left eye, where the specific cause or type of neovascularization is not documented. Corneal neovascularization can impair vision by causing corneal opacification and can be a sign of underlying ocular disease.

Use this code when the medical record clearly indicates corneal neovascularization in the left eye, but the ophthalmologist has not specified the etiology (e.g., infectious, inflammatory, traumatic). Documentation should mention "corneal neovascularization, left eye" without further detail regarding its nature.

• Do not use this code if the underlying cause of the corneal neovascularization is known and documented; instead, code the specific type.
• Ensure laterality is accurately documented and coded (left eye in this case).
• Consider querying the provider for more specific documentation if the cause is suspected but not explicitly stated.
