About H57.89

H57.89 is the ICD-10-CM diagnosis code for other specified disorders of eye and adnexa. It belongs to category H57 (other disorders of eye and adnexa), block H55-H57 (other disorders of eye and adnexa) 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 H57.8, choose H57.89 (Other specified disorders of eye and adnexa) only when documentation doesn't support a more specific option: brow ptosis (H57.81) and foreign body sensation eye (ocular) (H57.8A).

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 was added in FY2019, effective October 1, 2018.
