About coding sclera blue
The ICD-10-CM code for sclera blue is Q13.5 (Blue 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 Q13.5.
Within Q13 (congenital malformations of anterior segment of eye), Q13.5 is specifically for Blue sclera. Related codes cover coloboma of iris (Q13.0), absence of iris (Q13.1), other congenital malformations of iris (Q13.2), congenital corneal opacity (Q13.3), other congenital corneal malformations (Q13.4), other congenital malformations of anterior segment of eye (Q13.8) and congenital malformation of anterior segment of eye, unspecified (Q13.9).
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.
