Significant Duplicative Spending on Coronary Revascularization Procedures among VA and Medicare Dual Enrollees
More than one million Veterans are dually enrolled in a Medicare Advantage (MA) plan and the VA healthcare system. The federal government prepays private MA plans to cover Veterans; thus, if a dually-enrolled Veteran receives an MA-covered service at VA, the government is making two payments for the same service. Moreover, Medicare plans are prohibited by law from making payments for services already paid for by another government entity; thus, VA cannot collect reimbursements from MA plans for Medicare-covered services. This retrospective cohort study sought to describe where dually-enrolled VA-MA Veterans receive coronary revascularization and the associated costs. Among dually-enrolled Veterans (n=18,874) with at least one VA encounter who received coronary revascularization from January 1, 2010 to December 31, 2013, investigators examined the number of coronary artery bypass graft (CABG) surgeries and percutaneous coronary interventions (PCI) performed through VA and MA, and the associated VA costs. In addition, patient factors associated with receiving care through VA were assessed.
- A significant share of VA healthcare users, concurrently enrolled in a Medicare Advantage plan, received coronary revascularization procedures through VA, incurring significant duplicative federal healthcare spending of nearly $215 million from 2010 through 2013.
- Over the study period, 4,115 patients (22%) received either CABG or PCI through VA, 14,281 (75%) through MA, and 478 (3%) through both payers. Among this cohort, younger, non-white Veterans living in urban and rural counties were more likely to receive CABG or PCI through VA, whereas distance to a VA hospital did not independently influence the choice of VA versus MA for coronary revascularization.
- The growing number of Medicare beneficiaries opting into Medicare Advantage is likely to lead to an increase in duplicative billing. Given the financial pressures facing both Medicare and VA, government officials should consider policy solutions to mitigate duplicative federal spending.
- Investigators lacked detailed clinical information.
- Outside of fee-basis care, VA expenditures were estimated because VA does not assign costs nor charge for individual services.
