Abstract
BACKGROUND: We examined whether the recent reimbursement reductions on the bone mineral density (BMD) test affected BMD testing in female Medicare beneficiaries with or without supplemental private health insurance. METHODS: Retrospectively analyzing hospital administrative and clinical data on female Medicare beneficiaries (n=1320), we reviewed whether participants received BMD testing before (January 2004-December 2006) or after (January 2007-December 2009) reimbursement reductions for BMD testing. After adjusting for demographics and clinical characteristics, we performed Cox proportional hazard regression analyses of the BMD test including data from all study participants; we then performed separate regression analyses using data with or without supplemental private health insurance. RESULTS: In those without supplemental private health insurance (n=421), less frequent BMD testing occurred after reimbursement reductions for BMD testing (hazard ratio [HR] 0.67, 95% confidence intervals [CI] 0.34-0.98; p=0.03). By contrast, in the overall participants (n=1320) and those with supplemental private health insurance (n=899), the number of BMD tests did not change significantly after reimbursement reductions for BMD testing. CONCLUSIONS: We found a significant association between reimbursement reductions and decrease in BMD tests in female Medicare beneficiaries without supplemental private health insurance.
