About coding cornea transplant
The ICD-10-CM code for cornea transplant is Z94.7 (Corneal transplant status).
Within Z94 (transplanted organ and tissue status), Z94.7 is specifically for corneal transplant status. Related codes cover kidney transplant status (Z94.0), heart transplant status (Z94.1), lung transplant status (Z94.2), heart and lungs transplant status (Z94.3), liver transplant status (Z94.4), skin transplant status (Z94.5), bone transplant status (Z94.6), other transplanted organ and tissue status (Z94.8) and 1 more.
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.
