About coding one eye blindness
The ICD-10-CM code for one eye blindness is H54.40 (Blindness, one eye, unspecified eye). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H54.40.
Within H54.4, choose H54.40 (unspecified eye) only when documentation doesn't support a more specific option: right eye, normal vision left eye (H54.41) and left eye, normal vision right eye (H54.42).
Code first: any associated underlying cause of the blindness.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
