About coding eye complication

The ICD-10-CM code for eye complication is H57.9 (Unspecified disorder of eye and adnexa). The official index lists 18 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H57.9.

Within H57, choose H57.9 (Unspecified disorder of eye and adnexa) only when documentation doesn't support a more specific option: anomalies of pupillary function (H57.0), ocular pain (H57.1) and other specified disorders of eye and adnexa (H57.8).

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.
