Assessing the Promise and Risks of Income-Based Third-Party Payment Programs

Consumers' concerns about affordability limit participation in ACA marketplaces. Funded by local hospital systems and run by independent nonprofits, third-party payment (TPP) programs improve affordability for low-income consumers by paying premium costs not covered by tax credits.

To assess the potential of TPP to make marketplace coverage more affordable, without harming insurance risk pools.

Interviews in May and June 2016 with program administrators, hospital systems, carriers, and consumer groups in five localities and the Washington State marketplace.

The most effective local program reached 1,148 people, or 25 percent of all eligible marketplace enrollees. Other local programs served between 202 and 934 consumers; the Washington State program reached 1,133. Findings suggest that without TPP, numerous beneficiaries would have remained uninsured. Hospitals funding these programs reported net financial benefits, with declines in uncompensated care exceeding program costs. Carriers reported no adverse selection in these carefully designed programs.

Widespread adoption of TPP could help additional low-income consumers obtain marketplace coverage. Hospitals' financial gains from TPP programs make replication more feasible. However, broader policies, such as increased premium tax credits and cost-sharing reductions, are likely needed for major nationwide improvements to affordability.
