While disparities in access to reconstruction persist, a comprehensive analysis comparing state-based outcomes and national patterns in breast reconstruction as a result of Medicaid expansion has never been examined. In this study, we investigated how breast reconstruction rates changed as a result of Medicaid expansion and compared these state-based findings to national counterparts. Patient data from the Healthcare Cost and Utilization Project among states that chose to expand Medicaid were compared with those from states that did not expand. The difference-in-differences estimate of expansion to nonexpansion states was 7.05 (p = 0.10) for implant-based reconstruction, -11.56 (p = 0.01) for autologous reconstruction, and -7.08 (p = 0.18) for overall reconstruction. Comparing rates of nonexpansion states to national trends yielded estimates of -0.06 (p = 0.04), 0.06 (p = 0.01), and 0.004 (p = 0.90) for implant-based, autologous, and overall breast reconstruction, respectively. Similarly, comparing rates of expansion states to national trends yielded estimates of 0.02 (p = 0.38), -0.05 (p = 0.03), and -0.02 (p = 0.44) for implant-based, autologous, and overall breast reconstruction, respectively. In this study on national health policy, Medicaid expansion was associated with a significant increase in autologous rates while state-specific trends alone did not appear to predict the national outcomes of sweeping legislative changes that were differentially applied among states.
