Surgical and Transcatheter Mitral Valve Therapy: Medicare Utilization and Reimbursement

BACKGROUND We aimed to examine trends in the utilization and reimbursement of surgical and transcatheter mitral valve therapies and their changing relationship. METHODS A query of administrative data on US Medicare beneficiaries undergoing mitral valve therapy was conducted from 2015 to 2020 using the Centers for Medicare and Medicaid Services Part B National Summary Data File. Inflation adjustment was to the 2020 Consumer Price Index. Trend analysis was quantified with growth rate and simple linear regression calculations. RESULTS The annual number of all mitral valve procedures remained constant. Transcatheter mitral valve therapies increased by 313% with an increase of 1552 cases per year ( P < .001), whereas surgical mitral valve therapies decreased by 31.4% with a decline of 1446 procedures per year ( P [ .004). As a proportion of all mitral valve therapies, surgical therapies decreased from 91.8% to 65.0%. Annual Medicare reimbursements for transcatheter and surgical mitral valve therapies mirrored the annual procedural trends. For transcatheter mitral valve therapies, per -case reimbursement decreased by 14.1% ($1283.18 to $1102.88), and for surgical mitral valve therapies, per -case reimbursement decreased by 3.8% ($1480.65 to $1424.57). CONCLUSIONS Medicare utilization of mitral valve therapies has been stable in recent years, with growth of transcatheter volumes offset by a decrease in surgical volumes. This suggests that transcatheter therapy availability has not expanded the pool of patients with access to therapy. Nonetheless, case reimbursements decreased for both modalities.
