About coding optic disc congenital coloboma
The ICD-10-CM code for optic disc congenital coloboma is Q14.2 (Congenital malformation of optic disc). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q14.2.
Within Q14 (congenital malformations of posterior segment of eye), Q14.2 is specifically for congenital malformation of optic disc. Related codes cover congenital malformation of vitreous humor (Q14.0), congenital malformation of retina (Q14.1), congenital malformation of choroid (Q14.3), other congenital malformations of posterior segment of eye (Q14.8) and congenital malformation of posterior segment of eye, unspecified (Q14.9).
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.
