Addressing Housing-Related Social Needs Through Medicaid: Lessons From North Carolina's Healthy Opportunities Pilots Program.

North Carolina Medicaid's Healthy Opportunities Pilots program is the country's first comprehensive program to evaluate the impact of paying community-based organizations to provide eligible Medicaid enrollees with an array of evidence-based services to address four domains of health-related social needs, one of which is housing. Using a mixed-methods approach, we mapped the distribution of severe housing problems and then examined the design and implementation of Healthy Opportunities Pilots housing services in the three program regions. Four cross-cutting implementation and policy themes emerged: accounting for variation in housing resources and needs to address housing insecurity, defining and pricing housing services in Medicaid, engaging diverse stakeholders across sectors to facilitate successful implementation, and developing sustainable financial models for delivery.
