ACA Marketplace changes are technical and numerous but consequential. While more attention has been focused on cuts to Medicaid, upcoming changes to the ACA Marketplaces could lead to just as many people losing health insurance coverage.
Every summer, health insurers submit rate filings to state regulators detailing expectations and justifying premium rate changes for ACA-regulated health plans for the coming year. With the enhanced premium tax credits set to expire at the end of 2025, consumers can expect increases in how much they pay for coverage.
This analysis illustrates how provisions included in the House budget reconciliation bill could expose Marketplace enrollees with unpredictable incomes to higher penalties when filing taxes if they underestimate their incomes. About one in four potential Marketplace shoppers had incomes that varied at least 20 percent from the beginning to the end of the year.
The budget resolution is unusual because it establishes different tracks for reconciliation in each chamber: House committees are instructed to increase deficits by $2.3 trillion, with major cuts to Medicaid; and Senate committees are instructed to increase deficits by what amounts to $5.8 trillion, without clear implications for Medicaid cuts.
This brief explores the magnitude of the potential federal Medicaid funding cuts under the House budget resolution. This brief puts the $880 billion in cuts in context by comparing the size of the cuts to states’ tax revenues, spending on education, and the number of Medicaid enrollees covered for that cost.
As Congressional Republicans and President Trump search for trillions of dollars in cuts to mandatory federal spending that could help offset the cost of extending expiring tax cuts, this brief analyzes current support from the federal government for health programs and services, including both spending and tax subsidies as context for those federal budget discussions.
In the face of reduced federal funding for Medicaid, states could be left with difficult choices – raise revenue or cut spending. Cuts to Medicaid could mean eliminating coverage for children, parents, working adults or those who might need long term care; limiting benefits; or cutting rates for plans or providers.
House Republicans are considering deficit reductions of $5.5 trillion, which includes $2.3 trillion cuts in Medicaid… Cuts of this magnitude would put states at financial risk, forcing them to raise new revenues or reduce Medicaid spending
A per capita cap in Medicaid may be a solution in search of a problem. However, if a cap substantially reduced federal Medicaid spending over time, it would put states at financial risk and force cuts to services and rates paid to physicians, hospitals, and nursing homes.
With Election Day just over a month away, here is a timeline of significant ACA moments.
