  • Description:

    Asthma affects more than 25 million Americans, including 4.2 million children. The burden of asthma disproportionately affects people enrolled in Medicaid, among other disparate groups. Improved availability and accessibility of guidelines-based treatments and services may ensure positive health outcomes for people with asthma. In this article, we provide an update to the American Lung Association’s Asthma Guidelines-Based Care Coverage Project (the Project) to determine the extent of asthma care coverage and associated barriers in Medicaid programs for all 50 states, the District of Columbia, and Puerto Rico, and examine improvements in coverage since 2017.


    Findings from the Project, representing coverage from 2016–2017, were first published in Preventing Chronic Disease in 2018. The Project was updated in 2021 to reflect the National Asthma Education and Prevention Program guidelines 2020 Expert Panel Report-3 updates, which were finalized in December 2020. It now tracks coverage for 8 areas of guidelines-based care and 7 barriers to care in Medicaid programs by reviewing publicly available plan documents and engaging with Medicaid programs to review and confirm findings.


    Results from the Project, which reflect coverage in 2021–2022, show an increase in comprehensive coverage in Medicaid programs over the last 5 years. However, coverage remains inconsistent across programs, and barriers to accessing asthma care still exist.


    Although substantial improvement has been made to coverage, certain gaps and barriers to care must be addressed for patients to fully benefit from guidelines-based care to manage their asthma and improve health outcomes.
