MedicalResearch.com Interview with: Daniel Polsky PhD Executive Director, Leonard Davis Institute of Health Economics Professor of Medicine and Health Care Management Perelman School of Medicine and the Wharton School University of Pennsylvania Medical Research: What is the background for this study? What are the main findings? Dr. Polsky: The Medicaid Fee bump, a provision of the Affordable Care Act (ACA), raised Medicaid payments to Medicare levels in 2013 and 2014 for selected services and providers expired on January 1, 2015 before policymakers had much empirical evidence about its effects.   The federally funded increase in reimbursements was aimed at expanding access to primary care for the growing number of Medicaid enrollees. The reimbursement increase expired at the end of 2014 in most states.  We found that this policy worked to increase the number of providers offering primary care appointments to Medicaid patients.  The Medicaid pay bump was associated with a 7.7 percentage points increase in new patient appointment availability without longer wait times.   This increase in availability was largest in the states where primary care physicians received the largest increase in their Medicaid reimbursements.
