Q15.8Other specified congenital malformations of eye

Q15.8 is the ICD-10-CM diagnosis code for other specified congenital malformations of eye. It belongs to category Q15 (other congenital malformations 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 Q15, choose Q15.8 (Other specified congenital malformations of eye) only when documentation doesn't support a more specific option: congenital glaucoma (Q15.0) and congenital malformation of eye, unspecified (Q15.9).

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 743.8 (other specified anomalies of eye).
