The Diabetes Interventions Addressing Barriers to Enrollment, Technology, and Education Services (DIABETES) Act seeks to enhance access to critical diabetes care for Medicare beneficiaries. It addresses significant gaps in current Medicare coverage, particularly concerning advanced diabetes technologies and essential self-management education. The bill acknowledges the growing prevalence and high costs associated with diabetes, emphasizing the need for improved access to tools like continuous glucose monitors and automated insulin delivery systems. A key provision ensures continued access to diabetes technology for individuals enrolling in Medicare Part B, allowing providers to certify their ongoing use of covered devices during the initial 12 months. The Secretary of Health and Human Services is directed to develop certification forms and guidance to prevent disruptions in access. Furthermore, the bill mandates a process to consider new diabetes technologies for coverage under existing statutory authority. To improve diabetes self-management, the bill revises Medicare's coverage for diabetes outpatient self-management training services (DSMT) . It specifies an initial 10 hours of training, followed by 2 additional hours annually, and removes quantity limits if medically necessary. Crucially, it eliminates both the deductible and coinsurance for these vital training services, making them more affordable and accessible for beneficiaries. The legislation also requires the Secretary to establish new Healthcare Common Procedure Coding System (HCPCS) codes for insulin pump training and education by January 1, 2027, ensuring proper reimbursement for these services. It mandates a proposed national coverage determination for infusion pumps and continuous subcutaneous insulin infusion (CSII) within 180 days of enactment. Additionally, the bill directs the Comptroller General to report on barriers to accessing diabetes technologies and DSMT services across all federal health care programs. Finally, the bill aims to improve future access by requiring the Secretary to implement a model to test the impact of virtual diabetes outpatient self-management training services on health outcomes and expenditures. It also ensures that continuous glucose monitors and insulin pumps, when covered as durable medical equipment, will be excluded from competitive bidding programs starting in 2031, safeguarding innovation and beneficiary access.
