OBBBA Medicaid work requirements and concurrent ACA subsidy expiration create a compound coverage loss event of 15-17M Americans by 2030 — the largest single reversal of health coverage expansion since before the ACA

OBBBA's Medicaid work requirements take effect December 30, 2026, requiring expansion adults (19-64, 'able-bodied') to demonstrate 80 hours/month of work or community engagement. CBO projects 10.9M Americans become uninsured by 2034 from combined Medicaid and ACA losses. Urban Institute projects 4.9-10.1M lose Medicaid coverage in 2028 from work requirements and six-month redeterminations alone. Simultaneously, enhanced ACA premium tax credits expired January 1, 2026, and OBBBA did not restore them. This caused average ACA premiums to more than double (114% increase), with 9% of 2025 ACA enrollees now uninsured (KFF March 2026 poll). The critical insight: these two coverage-erosion vectors affect overlapping populations (under 400% FPL) but are tracked separately in most coverage estimates. The compound effect creates 15-17M fewer Americans with coverage by 2030 — the largest single reversal of health coverage expansion since before the ACA. The December 30, 2026 effective date means enrollment impact will be measurable starting Q1 2027, with state administrative capacity determining whether losses track toward the 4.9M or 10.1M end of the range.
