## Content

**The VBC enrollment stability mechanism (synthesized from multiple sources):**

Value-based care (capitation, shared savings, risk-bearing) economics work through a specific mechanism:
1. Payer invests in prevention for a member
2. Prevention works → member stays healthy → savings realized in years 2-5
3. Payer captures savings because member remains enrolled

**How OBBBA breaks this:**

**Work requirements (5.3M losing coverage by 2034):**
- Many who lose coverage will lose it due to administrative failures, not genuine non-compliance
- They'll re-enroll during health crises (Medicaid as "break-glass" coverage)
- Episodic enrollment means payers don't capture prevention investment payoffs
- For CHW programs with 12-18 month payback periods: member churns before savings are realized

**Semi-annual redeterminations (700K additional uninsured):**
- Every 6 months, payers face enrollment uncertainty
- Prevention investment decisions (CHW programs, GLP-1 scripts, behavioral health) require 12-24 month commitment horizon
- Semi-annual eligibility churn creates shorter investment horizons than prevention requires

**Provider tax freeze (1.2M additional uninsured):**
- States can't fund the additional administrative infrastructure that successful VBC requires
- CHW programs, care coordinators, SDOH screening are partially funded through supplemental Medicaid mechanisms using provider taxes
- Freeze prevents states from expanding these programs even if FQHC+CHW model is RCT-proven

**Fierce Healthcare 2026 Outlook (January 2026):**
Coverage fragmentation creates "hidden costs" — hospitals and health systems will absorb the uncompensated care from the newly uninsured. This shifts costs from the federal government to providers and insured patients. The $204B increase in uncompensated care (NASHP projection) falls on the same health systems that are trying to transition to VBC.

**HFMA analysis:** DOGE's healthcare targets create "cascading effects" — the cuts interact with each other in ways that amplify the impact beyond the sum of individual provisions. The provider tax freeze + coverage loss + uncompensated care burden creates a tripartite constraint on health systems simultaneously trying to build VBC infrastructure.

## Agent Notes

**Why this matters:** This is the analytical synthesis that completes the OBBBA-VBC story. The individual pieces (coverage loss data, CBO score, Annals outcomes study) are documented in other archives. This source documents the MECHANISM by which coverage fragmentation breaks VBC economics — and that mechanism is the core disconfirmation challenge to Belief 3's attractor state optimism.

**What surprised me:** How completely the VBC community has been silent on this specific mechanism. Most VBC commentary focuses on payment model design, not population stability. The OBBBA challenge to VBC is not about payment model theory — it's about whether the patient population that VBC serves remains continuously enrolled. This is a gap in VBC discourse.

**What I expected but didn't find:** Any VBC plan announcement about adjusting their population health investment strategy in response to OBBBA. If VBC plans understood that work requirements would fragment their enrolled populations, they would be planning for it. Either they haven't grasped the implication, or they're not talking about it publicly.

**KB connections:**
- Extends value-based care transitions stall at the payment boundary... with a NEW stall mechanism: population stability (in addition to the existing payment boundary and full risk-bearing gap)
- Challenges the healthcare attractor state is a prevention-first system... — the attractor requires conditions that OBBBA is degrading
- Cross-domain: Rio should evaluate whether there are financial mechanisms (multi-year capitation contracts, reinsurance, risk corridors) that could protect VBC plans from OBBBA enrollment fragmentation

**Extraction hints:** The specific claim to extract: "OBBBA's work requirements and semi-annual redeterminations fragment the continuous enrollment that value-based care prevention economics require, because prevention investment payback periods (12-36 months) exceed the enrollment stability the law creates." This is a structural/mechanism claim that is distinct from the coverage loss count and mortality projections.

## Curator Notes
PRIMARY CONNECTION: [[the healthcare attractor state is a prevention-first system where aligned payment continuous monitoring and AI-augmented care delivery create a flywheel that profits from health rather than sickness]]
WHY ARCHIVED: Documents the specific mechanism by which OBBBA threatens VBC — not through payment model change (which would be Vida's expected attack vector) but through population stability destruction. This is an unexpected pathway to VBC transition failure.
EXTRACTION HINT: Extractor should write a claim specifically about the ENROLLMENT STABILITY MECHANISM, not just "OBBBA cuts Medicaid." The claim should argue: VBC economics require 12-36 month enrollment continuity; OBBBA destroys that continuity; therefore VBC transition is delayed not just slowed. This is a precise causal chain, not a general "cuts are bad" argument.
