One of the most powerful tools that the federal government has used to increase access to care for rural populations is increased reimbursement for outpatient services. This study uses Medicare claims data to examine the basic patterns of use of the Medicare bonus program and addresses the following questions:
  • What proportion of eligible outpatient claims made to Medicare from designated Health Professional Shortage Areas (HPSAs) receive the permitted 10 percent bonus payment?
  • What is the distribution of bonus payments across physician specialties?
  • Are there major geographic variations in the pattern in which these bonus payments are made (i.e., where are the physicians generally based and where do the beneficiaries reside who obtain most of the bonus payments)?
  • Do the Health Service Areas that are more successful in receiving these bonus payments experience greater physician supply?
Although their urban counterparts are also being analyzed for policy and comparative purposes, emphasis is placed on rural physicians and rural Medicare beneficiaries. The project design consists of a retrospective analysis of Part B claims data for 1998 for the states of Alaska, Idaho, North Carolina, South Carolina and Washington. We are using data from our recent detailed physician supply and requirements work to determine the physician supply by discipline for the designated rural HPSAs. We are also correlating these data with our findings from the data analyses. Appropriate HCFA and AMA data are being linked to the claims files for analysis.
