Mandated Benefits for Diabetes Education and the Availability of Accredited Programs and Certified Diabetes Educators

States have the latitude to mandate coverage of diabetes self-management education (DSME) services for privately insured and Medicaid patients. The impact of these mandates on the supply of DSME resources is unknown. This study compared changes in the supply of DSME programs and program sites accredited by the American Association for Diabetes Educators (AADE) and certified diabetes educators (CDE) between states that did and did not mandate benefits for DSME. Using a unique combination of legal and programmatic data sources, the authors employed fixed effects regression models with clustered robust standard errors to compare changes in the supply of AADE-accredited DSME programs, program sites, and CDEs in states that mandated benefits with states that did not. Given the variation in state mandates, models also estimated the impact of "flexible" reimbursement provisions on the supply of resources among adopting states. The supply of DSME resources has increased over time, but results indicate that mandated benefits were not a significant driver of these changes in the supply. The impact of flexible reimbursement provisions varied. Interestingly, provisions of the Affordable Care Act were associated with an increased supply of resources. Results suggest that extending benefits to previously insured patients does not increase the supply of DSME resources, but a rapid increase in patients entering the health system does encourage growth.
