Background: The purpose of this study was to evaluate changes in open carpal tunnel release (OCTR) and endoscopic carpal tunnel release (ECTR) utilization, reimbursement, and patient demographics in the Medicare population from 2013 to 2021 at national and regional levels.
Materials and methods: The Medicare Physician & Other Practitioners database from 2013 to 2021 was queried to extract all instances of OCTR and ECTR. Utilization per 10,000 beneficiaries, inflation-adjusted reimbursement, and patient characteristics were extracted for OCTR and ECTR each year. Data were stratified by region based on US Census guidelines. Kruskal-Wallis tests and multivariable linear regressions were performed.
Results: From 2013 to 2021, national utilization per 10,000 beneficiaries increased by 6% for OCTR and by 50% for ECTR. In 2021, the Midwest had the greatest utilization of OCTR (29 of 10,000) and the lowest utilization of ECTR (7 of 10,000). Inflation-adjusted reimbursement declined for both OCTR and ECTR during the study period (10.3% and 11.8%, respectively), with the South having the lowest reimbursement for both procedures. The severity of patient comorbidity profiles and dual Medicare-Medicaid enrollees decreased for both procedures as well.
Conclusion: Both OCTR and ECTR utilization have increased, while inflation-adjusted reimbursement has decreased. Patient populations encompassed fewer dual Medicare-Medicaid enrollees, indicating surgeons may be more selective in operative indications. These findings should be addressed to ensure the economic sustainability of carpal tunnel release procedures and equitable access to quality hand care for all patients with Medicare.
