Cell therapy
About 38228: Autologous CAR T-cell administration
Report this service for administering a patient’s own genetically modified T cells as CAR T-cell therapy, rather than for collecting or preparing the cells.
This code identifies the administration step of autologous chimeric antigen receptor (CAR) T-cell therapy. A patient’s T lymphocytes are collected and modified for treatment, then the resulting cell product is administered back to that patient. Hematologists, oncologists, and other clinicians involved in cellular therapy typically oversee the infusion in a hospital or specialized treatment setting. The code is specific to CAR T-cell administration, not conventional chemotherapy or hematopoietic stem-cell transplantation.
Select the code for the actual administration of the autologous CAR T-cell product. Collection and preparation activities occur at different stages and are represented by separate codes in the CAR T sequence when applicable. Documentation should identify the autologous CAR T product and record that it was administered, including the date and supporting infusion documentation. CMS assigns physician work, practice expense, and malpractice relative values to the service; no additional payment rule is listed in the supplied CMS facts.
