Haglin JM, Arthur JR, Deckey DG, et al. - This study was undertaken to investigate trends in Medicare reimbursement to hospitals for total joint arthroplasty (TJA) patients from 2011 to 2017. Between 2011 and 2017, researchers included a sum of 3,368,924 primary TJA procedures billed to Medicare by hospitals. The mean Medicare reimbursement to hospitals decreased for TJA from 2011 to 2017 during the study period. The data demonstrated that the average charge submitted by hospitals increased. These data are important for the advancement of more agreeable reimbursement models in arthroplasty care as alternative payment models continue to undergo assessment and development.
