About Q14.3
Q14.3 is the ICD-10-CM diagnosis code for congenital malformation of choroid. It belongs to category Q14 (congenital malformations of posterior segment of eye), block Q10-Q18 (congenital malformations of eye, ear, face and neck) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Q14 (congenital malformations of posterior segment of eye), Q14.3 is specifically for congenital malformation of choroid. Related codes cover congenital malformation of vitreous humor (Q14.0), congenital malformation of retina (Q14.1), congenital malformation of optic disc (Q14.2), 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.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 743.53 (chorioretinal degeneration, congenital).
