Over 14.8 million person-months, Medicare Advantage beneficiaries had lower transplant rates than those in traditional Medicare (2.51 vs 4.60 per 1000 person-months; adjusted rate ratio [aRR], 0.71; 95% CI, 0.69-0.72). Absolute differences were widest among the youngest beneficiaries (aged 18-44 years) and were stable across calendar years (aRRs: 0.71 [95% CI, 0.68-0.73] in 2021; 0.70 [95% CI, 0.68-0.73] in 2022; and 0.70 [95% CI, 0.68-0.72] in 2023).
