About Z94.0

Z94.0 is the ICD-10-CM diagnosis code for kidney 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), Z94.0 is specifically for kidney transplant status. Related codes cover 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), corneal transplant status (Z94.7), other transplanted organ and tissue status (Z94.8) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 008 (Simultaneous Pancreas, Islet Cell and Kidney Transplant, relative weight 5.5146), DRG 019 (Simultaneous Pancreas, Islet Cell and Kidney Transplant with Hemodialysis, relative weight 7.5493), DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in Pre-MDC and MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), 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 V42.0 (kidney replaced by transplant).
