Lung transplantation and Affordable Care Act Medicaid expansion in the era of lung allocation score - a retrospective study.

This study evaluated the impact of Medicaid eligibility expansion (ME) on lung transplant (LT) listings and Medicaid coverage. Data on LT candidates aged 18-64 were obtained from the Scientific Registry of Transplant Recipients (N = 9153). The impact of ME was evaluated by comparing LT listings in 2011-2013 with listings in 2014-2016, as well as comparing states that had and had not adopted ME in 2014. LT listings increased by 7.7% nationally post-ME. In ME states, LT listings increased by 15.2%, whereas nonexpansion states decreased by 1.5%. LT candidates with Medicaid increased after ME nationally (8.3% vs. 9.9%, P = 0.006) and in ME states (9.7% vs. 11.5%, P = 0.036), but not in nonexpansion states (6.6% vs. 7.7%, P = 0.170). Following multivariable adjustment, LT listings in ME states had 58% greater odds for Medicaid compared to nonexpansion states (P < 0.001). Expansion of Medicaid provided greater healthcare access and increased LT listings, but only within states that adopted eligibility expansion.
