About coding bone transplant
The ICD-10-CM code for bone transplant is Z94.6 (Bone transplant status). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z94.6.
Within Z94 (transplanted organ and tissue status), Z94.6 is specifically for bone 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), corneal transplant status (Z94.7), 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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
