title: Reimbursement trends for outpatient interventional radiology procedures: comparison of hospital and freestanding physician office sites of service.
abstract: OBJECTIVE
  The aim of this study was to compare trends in reimbursement rates between hospital outpatient departments and freestanding physician offices for commonly performed interventional radiology procedures from 2006 through 2010.
  
  
  METHODS
  Using final rules data from the 2006 and 2008 Hospital Outpatient Prospective Payment System for Medicare and Medicare Physician Fee Schedule, reimbursement rates were calculated for a sample of procedures commonly performed by interventional radiologists in the outpatient setting. Hospital and freestanding reimbursement rates for 2006, 2008, and 2010 (projected) were adjusted for inflation to 2008 dollars and weighted by relative procedure frequency using Medicare Part B claims data. Reimbursements for the entire sample of procedures were compared year to year, by site of service, and by payment system. Individual procedure reimbursements were also trended.
  
  
  RESULTS
  In 2006, reimbursements for the entire procedure sample were 6% less in hospital outpatient departments than in freestanding offices. In 2008 and 2010, they are projected to be 3% and 23% greater, respectively, in hospital outpatient departments than in freestanding offices. Over the 4-year interval, reimbursements are projected to fall by 36% in freestanding offices and by 16% in hospital outpatient departments. Reimbursements to hospitals for facility costs are projected to decrease by 14%. Reimbursements to physicians for work done in hospital outpatient departments are projected to decrease by 23%.
  
  
  CONCLUSIONS
  Substantial reductions in calculated outpatient interventional radiology practice expenses being phased in between 2006 and 2010 under the Medicare Physician Fee Schedule seem to be dramatically reducing reimbursements for interventional procedures performed on outpatients, especially in freestanding offices. The impact of these practice expense reductions on interventional radiology seems to far outweigh that of the Deficit Reduction Act and other recent Medicare reimbursement changes.
