Background:
This study compared trends in use, predictive factors, and reimbursement of endoscopic carpal tunnel release (ECTR) withthose of open carpal tunnel release (OCTR) from 2010 to 2021 using a national administrative database.
Methods:
ECTR and OCTR patients were identified in the PearlDiver M151Ortho data set. Numeric and proportional utilization of these procedures was characterized for each year of study. Multivariate analysis was conducted to identify predictive factors for having ECTR performed. The average 90-day reimbursement of ECTR and OCTR was determined.
Results:
From 2010 through 2021, 441,023 ECTR and 1,767,820 OCTR procedures were identified. The proportional use of ECTR compared with OCTR rose from 2010 (15.7% of procedures) to 2021 (26.1%). Independent predictors of having ECTR performed rather than OCTR included geographic variation (compared with having surgery in the Midwest, Northeast odds ratio [OR], 1.53; West OR, 1.62; and South OR, 1.66), having Medicare or commercial insurance (compared with commercial, Medicare OR, 0.94, and Medicaid OR, 0.69), female sex, and fewer comorbidities. The average 90-day reimbursement for ECTR was $3,114.82, compared with $3,087.62 for OCTR.
Discussion:
As of 2021, over one-fourth of carpal tunnel releases are done endoscopically. Several factors independently predict whether patients receive ECTR or OCTR.
