Noncitizen immigrants, particularly those who are undocumented, face significant barriers to accessing health coverage and care and are significantly more likely than citizens to be uninsured.

This analysis examines early indicators of how the expiration of enhanced premium tax credits has affected effectuated enrollment levels (i.e., enrollment among people who have paid their premiums), plan selections, and out-of-pocket costs in 2026, drawing on plan selection and effectuated enrollment data from the Centers for Medicare & Medicaid Services (CMS) and state-based Marketplace (SBM) Open Enrollment reports, as well as KFF survey data and individual market enrollment estimates from Wakely Consulting Group.
The average Affordable Care Act (ACA) Marketplace deductible experienced the steepest increase in history—growing by 37% or over $1,000, from $2,759 in 2025 to $3,786 in 2026 as enhanced premium tax credits expired, according to a new KFF analysis. After the enhanced tax credits ended, many Marketplace shoppers shifted toward lower-premium, higher-deductible plans.
