Elevated Donor Specific Antibodies Following Heart Transplantation
A patient, who is status post heart transplant, is admitted due to elevated donor specific antibodies (DSAs) found on routine labs. The provider was concerned for acute rejection of the donor heart, and a diagnostic right heart catheterization and endomyocardial biopsy were performed. The findings were negative for acute cellular and antibody-mediated rejection (AMR). The patient received IVIG and Rituximab treatment for elevated DSAs. Should code R76.0, Raised antibody titer be assigned? What is the appropriate code assignment to capture an elevated DSA? ...

Article Overview
This Find-A-Code article explains how to approach diagnosis coding when elevated donor specific antibodies are identified after heart transplantation. It is intended for coding professionals and other revenue cycle users who need guidance on identifying the relevant diagnosis category, understanding the transplant-related clinical context, and distinguishing between similar nonspecific lab findings. The article also touches on the evaluation for rejection and the therapies given in response to the abnormal antibody finding.
Why This Topic Matters
Correctly capturing abnormal immunologic findings after transplant is important for accurate diagnosis coding and documentation of the clinical reason for evaluation and treatment. This topic is relevant for coders working with post-transplant encounters, laboratory abnormalities, and rejection workups.
