Expands Medicare coverage for outpatient diabetes self-management training by defining covered hours (an initial 10 hours that remain available until used, plus 2 hours per year thereafter), allowing additional medically necessary hours with clinician approval, updating medical nutrition therapy rules, and eliminating the Medicare deductible for these diabetes training services effective for services furnished on or after January 1, 2027. Creates a Medicare model test to evaluate covering virtual diabetes outpatient self-management training, requiring the Department to implement the model by January 1, 2026, measure health and cost outcomes (e.g., A1c, hospitalizations, medication adherence), and consult stakeholders shortly after enactment.
