About coding sclera ossification
The ICD-10-CM code for sclera ossification is H15.89 (Other disorders of sclera).
Within H15.8, choose H15.89 (Other disorders of sclera) only when documentation doesn't support a more specific option: Equatorial staphyloma (H15.81), localized anterior staphyloma (H15.82), staphyloma posticum (H15.83), scleral ectasia (H15.84) and ring staphyloma (H15.85).
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.
