About coding sclera disease
The ICD-10-CM code for sclera disease is H15.9 (Unspecified disorder of sclera). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H15.9.
Within H15, choose H15.9 (Unspecified disorder of sclera) only when documentation doesn't support a more specific option: scleritis (H15.0), episcleritis (H15.1) and other disorders of sclera (H15.8).
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.
