Geographic Variation in Cardiovascular Procedure Use Among Medicare Fee-for-Service vs Medicare Advantage Beneficiaries

Study Questions:

The extent to which different payment models influence observed geographic variation in the use of invasive cardiac procedures is unknown. How do different financial incentives between Medicare Advantage (i.e., managed care plan for Medicare) and Medicare fee-for-service (FFS) reimbursement influence use of invasive cardiac procedures like coronary angiography and percutaneous coronary intervention (PCI)?
