About coding orbit malformation
The ICD-10-CM code for orbit malformation is Q10.7 (Congenital malformation of orbit).
Within Q10 (congenital malformations of eyelid, lacrimal apparatus and orbit), Q10.7 is specifically for congenital malformation of orbit. Related codes cover congenital ptosis (Q10.0), congenital ectropion (Q10.1), congenital entropion (Q10.2), other congenital malformations of eyelid (Q10.3), absence and agenesis of lacrimal apparatus (Q10.4), congenital stenosis and stricture of lacrimal duct (Q10.5) and other congenital malformations of lacrimal apparatus (Q10.6).
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.
