Abstract
INTRODUCTION
Episode-based bundled payments were introduced by Medicare in 2013 as the Bundled Care Improvement Initiative (BPCI) in order to improve care coordination and cost efficiency. BPCI has been implemented for orthopedic, cardiac, and spine procedures, but has not yet been applied to cranial neurosurgical procedures. We project the cost of episode-based bundled payments for cranial neurosurgical procedures.
METHODS
We performed a large retrospective observational study using the MarketScan administrative database to project bundled payment costs for common cranial neurosurgical procedures. Operations were classified into 4 groups: craniotomy for unruptured aneurysm, craniotomy for meningioma, craniotomy for malignant glioma, and craniotomy for metastasis. We project 30-, 60-, and 90-d bundle payments for each category, and analyze the contributions of postdischarge costs to total bundle payments at each time point.
RESULTS
We identified 15 276 procedures that met our inclusion criteria. We observed significant variability between groups, with 90-d bundle projected costs ranging from $58,200 for craniotomy for meningioma to $102,073 for craniotomy for malignant glioma. We also found significant variability in projected bundled payments within each class of operation. On average, payment for the index hospitalization accounted for 85% of projected costs for a 30-d bundle and 70.5% of projected costs for a 90-d bundle. Multivariate analysis showed that medical comorbidities, adjuvant therapies, and payer status significantly contributed to projected cranial bundle costs.
CONCLUSION
For the first time in our knowledge, we report projected costs of 30-, 60-, and 90-d episode-based bundled payments for common elective vascular and tumor cranial operations. As previously identified in the orthopedic literature, there is significant cost variability in total bundle payments within each cranial procedure. Compared to spine and orthopedic procedures, postdischarge costs significantly impact total bundle payments in cranial neurosurgery.
