Financial Burden of Revision Hip and Knee Arthroplasty at an Orthopedic Specialty Hospital: Higher Costs and Unequal Reimbursements

As demand for primary total joint arthroplasty (TJA) continues to grow, a proportionate increase in revision TJA (rTJA) is expected. It is essential to understand costs and reimbursement of rTJA as our country moves to bundled payment models. We aimed (1) to characterize implant and total hospital c...

Zusammenfassung:As demand for primary total joint arthroplasty (TJA) continues to grow, a proportionate increase in revision TJA (rTJA) is expected. It is essential to understand costs and reimbursement of rTJA as our country moves to bundled payment models. We aimed (1) to characterize implant and total hospital costs, (2) assess reimbursement, and (3) determine revenue for rTJA in comparison with primary TJA. The average implant and total hospital cost of all primary and rTJA procedures by diagnosis-related group (DRG) was calculated using time-driven activity-based costing at an orthopedic hospital from 2018 to 2020. Average reimbursement and payer type were assessed by DRG. Revenue was calculated by deducting average time-driven activity-based costing total costs from reimbursement. 13,946 arthroplasties were included in the study. Implant cost comprised 55.8% of total hospital costs for rTJA DRG 468, compared with 43.6% of total hospital costs for primary TJA DRG 470. Total hospital costs for DRG 468 were 61.1% more than DRG 470. Reimbursement for rTJA was 1.23x more than primary TJA. Private payers paid 23.2% more than Medicare for rTJA. Margin for DRG 468 was 1.5% less than primary DRG 470. rTJA requires more hospital resources and costs than primaries, yet hospital reimbursement may be inadequate with the additional expenditures necessary to provide optimal care. If hospitals cannot perform revision services under the current reimbursement model, patient access may be limited. Implant costs are a major contributor to overall rTJA cost. Strategies are needed to reduce revision implant costs to improve value of care. Level III, economic and decision analysis.
