Abstract
STUDY DESIGN: Retrospective Cohort Study.
OBJECTIVE: To explore the differences in Medicare reimbursement for lumbar fusion performed at an orthopaedic specialty hospital (OSH) and a tertiary referral center and to elucidate drivers of Medicare reimbursement differences.
SUMMARY OF BACKGROUND DATA: To provide more cost-efficient care, appropriately selected patients are increasingly being transitioned to OSHs for lumbar fusion procedures. There are no studies directly comparing reimbursement of lumbar fusion between tertiary referral centers (TRC) and OSHs.
METHODS: Reimbursement data for a tertiary referral center and an orthopaedic specialty hospital were compiled through the Centers for Medicare and Medicaid Services. Any patient with lumbar fusions between January 2014 and December 2018 were identified. OSH patients were matched to TRC patients by demographic and surgical variables. Outcomes analyzed were reimbursement data, procedure data, 90-day complications and readmissions, operating room times, and length of stay (LOS).
RESULTS: A total of 114 patients were included in the final cohort. The tertiary referral center had higher post-trigger ($13,554 vs. $8,541, P < 0.001) and total episode ($49,973 vs. $43,512, P < 0.010) reimbursements. Lumbar fusion performed at an OSH was predictive of shorter OR time (β=0.77, P < 0.001), shorter procedure time (β=0.71, P < 0.001), and shorter LOS (β=0.53, P < 0.001). There were no significant differences in complications (9.21% vs. 15.8%, P =0.353) or readmission rates (3.95% vs. 7.89%, P =0.374) between the 2 hospitals; however, our study is underpowered for complications and readmissions.
CONCLUSION: Lumbar fusion performed at an OSH, compared with a tertiary referral center, is associated with significant Medicare cost savings, shorter perioperative times, decreased LOS, and decreased utilization of post-acute resources.
