About coding Keratoglobus
The ICD-10-CM code for Keratoglobus is H18.79 (Other corneal deformities). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H18.79.
Within H18.7, choose H18.79 (Other corneal deformities) only when documentation doesn't support a more specific option: unspecified corneal deformity (H18.70), corneal ectasia (H18.71), corneal staphyloma (H18.72) and Descemetocele (H18.73).
To report this condition, pick the subcode that matches the documentation: H18.791 (right eye), H18.792 (left eye), H18.793 (bilateral) and H18.799 (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.
