Abstract
BACKGROUND
The purpose of this study was to investigate whether decision-making regarding implant selection affects the reimbursement margins for the surgical fixation of ankle fractures.
METHODS
All ankle fractures treated between 2010 and 2017 within a single-insurer database were identified via Current Procedural Terminology codes by review of electronic medical record. Implant cost was determined via the implant record cross-referenced with the single contract institutional charge master database. The Time-Driven Activity-Based Costing (TDABC) technique was used to determine the costs of care during all activities throughout the 1-year episode of care. Statistical analysis consisted of multiple linear regression and goodness-of-fit analyses.
RESULTS
In all, 249 patients met inclusion criteria. Implant costs ranged from $173 to $3944, averaging $1342 ± $751. The TDABC-estimated cost of care ranged from $1416 to $9185, averaging $3869 ± $1384. Finally, the total reimbursed cost of care ranged between $1335 and $65 645, averaging $13 954 ± $9445. The implant costs occupied an estimated 34.7% of the TDABC-estimated cost of care per surgical encounter. Implant cost, as a percentage of the overall TDABC, was estimated as 36.2% in the inpatient setting and 33% in the outpatient setting, which was the second highest percentage behind surgical costs in both settings. We found a significant increase in net revenue of $1.93 for each dollar saved on implants in the outpatient setting, whereas the increase in net revenue per dollar saved of $1.03 approached significance in the inpatient setting.
CONCLUSION
There is a direct relationship between intraoperative decision-making, as evidenced by implant choices, and the revenue generated by surgical fixation of ankle fractures. Intraoperative decision-making that is cognitive of implant cost can facilitate adoption of institutional cost containment measures and prompt increased healthcare value.
