About H54.40

H54.40 is the ICD-10-CM diagnosis code for blindness, one eye, unspecified eye. It belongs to category H54 (blindness and low vision), block H53-H54 (visual disturbances and blindness) and chapter 7 (diseases of the eye and adnexa). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 369.02 (better eye: near-total vision impairment; lesser eye: not further specified), 369.05 (better eye: profound vision impairment; lesser eye: not further specified), 369.60 (profound impairment, one eye, impairment level not further specified) and 4 more.
