Congressional Republicans are considering a budget reconciliation package that would significantly alter Medicaid and the Affordable Care Act (ACA). The proposed changes include work and reporting requirements for certain Medicaid enrollees, codifying changes to the ACA Marketplaces, and allowing states to impose new cost-sharing requirements. These changes are estimated to increase the number of uninsured people by at least 13.7 million by 2034, according to the Congressional Budget Office (CBO).

The Medicaid provisions in the proposal would reduce enrollment by at least 7.7 million people, primarily due to new work and reporting requirements, stricter eligibility renewal processes, and lower federal matching rates for states that cover immigrants. Additionally, the proposal would delay streamlined eligibility and enrollment processes, impose new verification requirements, and reduce retroactive coverage.

The codification of the ACA Marketplace Integrity and Affordability Proposed Rule would also lead to an estimated 1.8 million more uninsured people by 2034. This rule would shorten the open enrollment period, restrict special enrollment periods, and impose new documentation requirements for income verification.

Furthermore, the expiration of enhanced premium tax credits, which are set to expire at the end of 2025, would lead to an estimated 4.2 million more uninsured people. These tax credits have reduced premium payments by an average of $705 per year and have led to a significant increase in ACA Marketplace enrollment. Without these credits, enrollees’ out-of-pocket premium payments would increase by over 75% on average, with lower-income and older enrollees being disproportionately affected.

Overall, the proposed changes would lead to a significant increase in the uninsured rate, reversing years of progress in reducing the number of uninsured Americans. The CBO estimates that the uninsured rate would increase by about 30% if these changes go into effect. The proposed changes would also have a disproportionate impact on vulnerable populations, including low-income individuals, older adults, and people with disabilities.
