About Z94.7
Z94.7 is the ICD-10-CM diagnosis code for corneal transplant status. It belongs to category Z94 (transplanted organ and tissue status), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
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 V42.5 (cornea replaced by transplant).
