domains/health/SDOH interventions show strong ROI but adoption stalls because Z-code documentation remains below 3 percent and no operational infrastructure connects screening to action.md

 England's social prescribing provides international counterpoint: 1.3M annual referrals with 3,300 link workers represents the operational infrastructure that US SDOH interventions lack. However, UK achieved scale without evidence quality - 15 of 17 economic studies were uncontrolled, 38% attrition, SROI ratios of £1.17-£7.08 but ROI only 0.11-0.43. This suggests infrastructure alone is insufficient without measurement systems.

+Community health worker programs demonstrate the same payment boundary stall: only 20 states have Medicaid State Plan Amendments for CHW reimbursement 17 years after Minnesota's 2008 approval, despite 39 RCTs showing $2.47 ROI. The billing infrastructure bottleneck is identical to Z-code documentation failure — SPAs typically use 9896x CPT codes but uptake remains slow because community-based organizations lack contracting infrastructure and Medicaid does not cover provider travel costs (the largest CHW overhead expense). 7 states have established dedicated CHW offices and 6 enacted new reimbursement legislation in 2024-2025, but the gap between evidence (strong) and operational infrastructure (absent) mirrors the SDOH screening-to-action gap.

 CMS BALANCE Model demonstrates policy recognition of the VBC misalignment by implementing capitation adjustment (paying plans MORE for obesity coverage) plus reinsurance (removing tail risk) rather than expecting prevention incentives to emerge from capitation alone. This is explicit structural redesign around the identified barriers.

+CHW reimbursement infrastructure demonstrates the same payment boundary stall in the SDOH domain: 20 states with approved SPAs after 17 years, with billing code uptake remaining slow even where reimbursement is technically available. The bottleneck is not policy approval but operational infrastructure — CBOs cannot contract with healthcare entities, transportation costs are not covered, and 'community care hubs' are emerging as coordination infrastructure. This parallels VBC's 60% touch / 14% risk gap: technical capability exists but the operational infrastructure to execute at scale does not.
