About coding eyelid accessory
The ICD-10-CM code for eyelid accessory is Q10.3 (Other congenital malformations of eyelid).
Within Q10, choose Q10.3 (Other congenital malformations of eyelid) only when documentation doesn't support a more specific option: congenital ptosis (Q10.0), congenital ectropion (Q10.1), congenital entropion (Q10.2), absence and agenesis of lacrimal apparatus (Q10.4), congenital stenosis and stricture of lacrimal duct (Q10.5), other congenital malformations of lacrimal apparatus (Q10.6) and congenital malformation of orbit (Q10.7).
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.
