RESUMO
INTRODUCTION: Although previous studies have demonstrated inconsistencies between surgeon work and reimbursement, no previous study has calculated expected relative value units (RVUs) based on procedure-specific variables. Our study aimed to evaluate how measures of physician workload and surgical complexity correlate with the work RVUs (wRVUs) assigned to orthopaedic procedures and compare our predicted wRVUs with actual wRVUs. METHODS: The National Surgical Quality Improvement Program was used to identify orthopaedic surgeries with the highest procedural volume in 2019. For each Current Procedural Terminology (CPT) code, variables related to surgical complexity and postoperative management were retrieved. A multivariable linear regression was conducted, and R 2 values were calculated. RESULTS: A total of 229,792 cases from the top 20 CPT codes by frequency in 2019 were identified. Base RVU values ranged from 7.03 mRVUs for arthroscopic meniscectomy to 30.28 mRVUs for revision total hip arthroplasty. A total of 15 (75%) of the projected mRVUs were lower than the actual mRVU of the procedure. For the 5 (25%) procedures with mRVU projections higher than actual values, the largest differences were seen for CPT codes 29,888 (arthroscopic anterior cruciate ligament [ACL] repair; difference: 7.81), 22,630 (posterior arthrodesis of the lumbar interbody; difference: 7.75), and 27,487 (revision total knee arthroplasty; difference: 4.04). CONCLUSION: Our analysis demonstrates that current orthopaedic wRVUs do not appropriately compensate for objective measures of overall complexity as it relates to each procedure. Significant undercompensation in projected RVUs was noted for several high-volume orthopaedic procedures including arthroscopic ACL repair and revision total knee arthroplasty.
