Regional differences in reimbursement, volume, and patient characteristics exist for rotator cuff repairs: a temporal...

Prior studies have demonstrated declining reimbursement and changing procedural utilization across multiple orthopedic subspecialties, yet a comprehensive examination of this has not been performed for rotator cuff repair (RCR), particularly at a geographic level. The purpose of this study was to evaluate changes in reimbursement, utilization, and patient populations for open and arthroscopic RCRs from 2013 to 2021 at a national and regional level.

The Medicare Physician and Other Practitioners database from years 2013 to 2021 were queried to extract all episodes of open chronic RCR, open acute RCR, and arthroscopic RCR. Utilization was measured as procedural volume per 10,000 Medicare beneficiaries. Inflation-adjusted reimbursement, utilization, surgeon information, and patient characteristics were extracted for each procedure for each year. Data was stratified geographically based on US Census regions and rural-urban commuting codes. Kruskal-Wallis tests and linear regressions were performed to compare geographical areas.

Between 2013 and 2021, arthroscopic RCR utilization increased by 9.4% (11.0/10,000-12.0/10,000), while open chronic RCR utilization decreased by 58.8% (2.0/10,000-0.8/10,000). During that time, average inflation-adjusted reimbursement declined by 10.0% and 11.3% for arthroscopic and open chronic RCR, respectively. The increase in utilization and decrease in reimbursement was greatest in the Midwest. In 2021, arthroscopic RCR utilization was 12.0/10,000, while average reimbursement was $846.87, nationally. Utilization was highest in the South (14.5/10,000) and lowest in the Northeast (8.1/10,000) (P < .001). Alternatively, reimbursement was highest in the Northeast ($904.60) and lowest in the South ($830.80) (P < .001). The proportion of patients who were male, Medicaid eligible, or non-White was highest in the West (P < .001). Patients in the West also had the fewest comorbidities. Increased patient comorbidities, when controlling patient demographics, were associated with lower reimbursement nationally and within the Northeast (P < .001).

Geographical discrepancies in RCR utilization and reimbursement exist. The South consistently demonstrates the highest utilization of RCR, while also having the lowest reimbursement. Alternatively, the Northeast has the lowest utilization but the highest reimbursement. Increased patient population comorbidities were associated with reduced RCR reimbursement for surgeons in the Northeast, but not in other regions.
