Cost comparison between medicare and private insurance for robotic transhiatal esophagectomy.

Esophageal cancer is a significant health concern, with the robotic platform being increasingly adopted for transhiatal esophagectomy (THE). While literature exists regarding the cost of robotic THE and its benefits, there is limited data analyzing cost and concurrent hospital reimbursement based on payor or provider. This study aimed to compare hospital reimbursement after robotic THE for patients with Medicare versus private insurance. With IRB approval, a prospective study of 85 patients from 2012 to 2022 who underwent robotic THE was conducted. Private insurance was defined as coverage excluding Medicare, Medicaid, or self-pay. Statistical analyses involved Student's t test, Chi-square test, and Fisher's exact test, with p ≤ 0.05 considered statistically significant. Data are presented as median (mean ± standard deviation). Among the 85 patients, 64 had Medicare, and 21 had private insurance. Medicare patients exhibited more frequent history of prior abdominal or thoracic surgeries (41% vs 10%, p < 0.01). Both groups showed no differences in factors like sex, body mass index, ASA classification, operative duration, estimated blood loss, conversions to 'open', tumor size, and major postoperative complications (Clavien-Dindo ≥ III). Similarly, metrics such as hospital stay duration, in-hospital mortality, 30-day readmission, and various financial components including total and variable costs, hospital reimbursement, and net margin were consistent across both. Despite Medicare patients being older and often having a broader operative history, hospital costs and reimbursements did not differ from patients with private insurance post-robotic THE. The robotic platform appears to mitigate potential disparities in hospitalization costs and hospital reimbursement for THE between Medicare and private insurance.
