About coding eye adnexa distortion
The ICD-10-CM code for eye adnexa distortion is Q15.8 (Other specified congenital malformations of eye).
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.
