Federal Medicaid work requirements project 4.9-10.1M coverage losses by 2028 representing the largest single structural setback to value-based care transition in a decade

RWJF projects 4.9-10.1 million people will lose Medicaid coverage specifically from work requirements by 2028, compared to CBO's 11.8M total OBBBA Medicaid impact by 2034. This means work requirements alone account for 40-85% of projected Medicaid losses, making them the dominant coverage loss mechanism within OBBBA. State implementation variation is extreme: strictest states (CT, MA, MD, MN, MO, NY, VT, WI) project 60%+ enrollment declines, while least stringent states (ND, SD) project 18-19% declines. This is the largest single structural contraction of the insured pool since the pre-ACA era. For value-based care, this matters because VBC prevention models require multi-year enrollment stability to realize ROI—a 5-10M person coverage loss destroys the enrollment base needed for Medicaid managed care VBC contracts. Medicare Advantage covers ~50% of Medicare beneficiaries making VBC viable for elderly populations, and Medicaid managed care covers ~75% of Medicaid enrollees making VBC viable for low-income adults. A 10M+ Medicaid coverage loss shrinks the Medicaid managed care pool by 13-20%, worsening risk pool composition and unit economics for value-based contracts.

Nebraska's 25,000 at-risk estimate (36% of subject population) provides first calibration data for CBO's 4.9-10.1M national projection. State variation modeling shows 60%+ enrollment decline in strict-policy states (CT, MA, MD, MN, MO, NY, VT, WI) versus 18-19% in least stringent (ND, SD). Actual enrollment data will be observable Q3-Q4 2026 when first renewal cycles complete.

Chartis projects hospital operating margins will decline approximately 12% in expansion states if work requirements take effect. First documented OBBBA-attributable facility closure occurred in Virginia (3 rural clinics). Preemptive workforce reductions and state Medicaid rate cuts are occurring in 2026 before federal provisions fully phase in, front-loading the economic damage.

Peer-reviewed Lancet study projects that the 4.8M-10.1M coverage losses will translate to 7,049-9,252 excess deaths annually, plus 113,607 additional cases of uncontrolled diabetes, 135,135 cases of hypertension, and 37,800 cases of high cholesterol. This quantifies the clinical consequence of the VBC structural setback in mortality and morbidity terms.

Source: Urban Institute state-level OBBBA enrollment projections

Urban Institute modeling provides state-level granularity: expansion enrollment falls 37-68% (low mitigation), 30-54% (medium), or 18-33% (high mitigation) across all states. Every expansion state loses coverage—no state is protected. The 30% self-employed, 50-64 age cohort, and caregivers are highest-risk populations. 3 in 10 young adults in Medicaid expansion age range are vulnerable.

ASTHO confirms Urban Institute 4.9-10.1M projection for 2028, with variance driven by state administrative capacity (high-mitigation vs. low-mitigation scenarios). Nebraska implementing earliest (May 1, 2026), with federal effective date December 30, 2026. States may delay to December 31, 2028, creating 2.5-year implementation window that determines coverage loss magnitude.
