About coding cornea neovascularization
The ICD-10-CM code for cornea neovascularization is H16.40 (Unspecified corneal neovascularization). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H16.40.
Within H16.4, choose H16.40 (Unspecified corneal neovascularization) only when documentation doesn't support a more specific option: Ghost vessels (corneal) (H16.41), Pannus (corneal) (H16.42), localized vascularization of cornea (H16.43) and deep vascularization of cornea (H16.44).
To report this condition, pick the subcode that matches the documentation: H16.401 (right eye), H16.402 (left eye), H16.403 (bilateral) and H16.409 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
