About coding stem cells transplant
The ICD-10-CM code for stem cells transplant is Z94.84 (Stem cells transplant status).
Within Z94.8 (other transplanted organ and tissue status), Z94.84 is specifically for stem cells transplant status. Related codes cover bone marrow transplant status (Z94.81), intestine transplant status (Z94.82), pancreas transplant status (Z94.83) and other transplanted organ and tissue status (Z94.89).
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 814 (Reticuloendothelial and Immunity Disorders with MCC, relative weight 2.0729), DRG 815 (Reticuloendothelial and Immunity Disorders with CC, relative weight 1.0444) and DRG 816 (Reticuloendothelial and Immunity Disorders without CC/MCC, relative weight 0.7381), in MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
