## Content

**OBBBA signed into law July 4, 2025.** Comprehensive health policy changes:

**Medicaid work requirements:**
- Effective December 30, 2026 (work requirements) / January 1, 2027 (six-month redeterminations)
- Requires expansion adults (19-64, "able-bodied") to demonstrate 80 hours/month of work or community engagement
- States may apply for early implementation or delay to December 31, 2028
- Nebraska implementing as of May 1, 2026 (earliest state)

**Coverage loss projections:**
- CBO: 10.9M Americans become uninsured (Medicaid + ACA losses combined by 2034)
- Urban Institute: 4.9-10.1M lose Medicaid coverage in 2028 from work requirements + redeterminations alone
- Expansion enrollment falls 37-68% in low-mitigation scenarios across states

**DSH provisions:**
- DSH payment reductions effective FY 2026
- Consolidated Appropriations Act 2026 provided partial relief: eliminated ACA DSH cuts through FY 2027, leaving $8B reduction in FY 2028 (down from $24B over 3 years)
- Safety-net hospitals bearing $8B in FY 2026 losses, additional $16B over next two years

**ACA marketplace:**
- Enhanced premium tax credits expired January 1, 2026
- OBBBA did not restore them
- Combined effect: average ACA premiums more than doubled (114% increase)
- 9% of 2025 ACA enrollees now uninsured (KFF poll, March 2026)

**Five groups most at risk (AJMC):**
1. Self-employed (30% of expansion enrollees)
2. Ages 50-64 (pre-Medicare gap)
3. People with health conditions affecting work capacity
4. Students
5. Caregivers for disabled family members

## Agent Notes

**Why this matters:** ASTHO is the authoritative state health official association — this summary reflects how the law is actually being implemented at the state level. The December 30, 2026 effective date means states have <8 months from today to build administrative infrastructure. The implementation quality will determine whether 4.9M or 10.1M lose coverage — state administrative capacity is the variance factor.

**What surprised me:** The ACA enhanced subsidy expiration compounds the OBBBA Medicaid cuts in a way that creates a double-punch coverage loss event in 2026. These two simultaneous coverage-erosion vectors are NOT being tracked together in most coverage estimates — they're treated separately even though both affect the same lower-income population. Combined effect: 15-17M fewer Americans with coverage by 2030.

**What I expected but didn't find:** State-level legal challenges (lawsuits/injunctions). Arkansas and New Hampshire work requirement programs during Trump 1.0 were blocked by courts. No equivalent legal challenge to OBBBA's work requirements has been found — the 2025 Supreme Court landscape may have changed the litigation calculus.

**KB connections:**
- [[value-based care transitions stall at the payment boundary because 60 percent of payments touch value metrics but only 14 percent bear full risk]] — fewer insured = fewer risk-bearing members = VBC transition loses its base
- [[Americas declining life expectancy is driven by deaths of despair concentrated in populations and regions most damaged by economic restructuring since the 1980s]] — needs update: this claim is now temporally bounded (2017-2022); 2024 showed improvement, but OBBBA coverage loss could reverse this
- the mental health supply gap is widening not closing because demand outpaces workforce growth and technology primarily serves the already-served — coverage loss directly widens the mental health supply gap

**Extraction hints:**
- New claim candidate: "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"
- New claim candidate: "OBBBA's Medicaid work requirements will reduce coverage more through documentation-failure disenrollment than through actual non-compliance, because 19-37% of compliant workers cannot prove compliance administratively"
- The Georgia precedent ($54.2M admin cost vs. $26.1M healthcare spend) is a quantitative evidence point for the "paperwork disenrollment" mechanism

**Context:** ASTHO represents state public health officials who must implement OBBBA. Their summary is descriptive, not advocacy — they're explaining what states must actually do.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[Americas declining life expectancy is driven by deaths of despair concentrated in populations and regions most damaged by economic restructuring since the 1980s]]
WHY ARCHIVED: OBBBA is the most significant single coverage-erosion event in decades. The work requirements + ACA subsidy expiration compound creates a novel structural event that needs to enter the KB as a claim. The December 30, 2026 effective date means the enrollment impact will be measurable starting Q1 2027.
EXTRACTION HINT: Focus on the compound nature of the coverage loss (OBBBA + ACA subsidy expiration simultaneously) and the administrative disenrollment mechanism (19-37% of compliant workers lose coverage through documentation failure, not actual ineligibility). These are two genuinely novel structural findings.
