This study investigated self-reported sources of medication nonadherence, measuring both cost- and non\u2013cost-related medication nonadherence among community-dwelling Medicare Part D beneficiaries in 2022. A total of 13.7% of beneficiaries (4 589 843) reported some type of medication nonadherence; 7.5% reported medication nonadherence related to cost and 6.2% reported for non-cost reasons. Beneficiaries reporting food insecurity, poor functional status, and lack of understanding of the Part D benefit were more likely to report both types of medication nonadherence after adjustment for sociodemographic factors. Beneficiaries receiving the Low-Income Subsidy had lower odds of reporting cost-related but greater odds of reporting non\u2013cost-related medication nonadherence. These findings suggest that non\u2013cost-related sources of medication nonadherence, such as beneficiary preferences or beliefs, understanding of their health situation or insurance coverage, and ability to fill a prescription, are significant contributors to overall nonadherence. Non\u2013cost-related medication nonadherence should be considered alongside recent changes to the Part D benefit and in future Part D Centers for Medicare and Medicaid Services (CMS) Innovation Center models, such as the proposed Medicare $2 Drug List Model, in order to maximize the impact of these initiatives.<\/jats:p>","DOI":"10.1093\/haschl\/qxae152","type":"journal-article","created":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T08:55:20Z","timestamp":1732006520000},"source":"Crossref","is-referenced-by-count":0,"title":["Non\u2013cost-related
