Staying informed about the latest legislation and policies related to diabetes is crucial for healthcare professionals preparing for the Certified Diabetes Educator (CDE) exam. Recent updates reflect ongoing efforts to improve patient care, access to medications, and public health initiatives. As the policy landscape evolves rapidly, CDE candidates must understand how federal and state laws shape clinical practice, patient education, and advocacy. This article provides an expanded overview of key legislative developments, state-level innovations, and emerging trends, along with their implications for the CDE exam. By mastering these topics, aspiring diabetes educators can provide informed, comprehensive care and help patients navigate complex healthcare systems.

Recent Federal Legislative Developments

Over the past year, several key legislative changes have been enacted at both federal and state levels. These include measures aimed at expanding access to insulin, reducing out-of-pocket costs, and enhancing diabetes education programs. Understanding these federal actions is foundational for CDE candidates because they directly affect patient affordability and medication adherence.

The Inflation Reduction Act of 2022

The Inflation Reduction Act (IRA) is arguably the most significant federal law affecting diabetes care in recent years. Passed in August 2022, it introduced a $35 per month cap on insulin copays for Medicare beneficiaries enrolled in Part D prescription drug plans and Part B for insulin used through a pump. This cap means that for roughly 3.3 million Medicare beneficiaries with diabetes, out-of-pocket expenses for insulin cannot exceed $35 per month, regardless of the number of insulin prescriptions. The IRA also eliminated the deductible for insulin covered under Part D, further lowering costs. Additionally, the law increased funding for diabetes research at the National Institutes of Health (NIH) and expanded community-based health programs aimed at prevention and management. For CDE candidates, understanding the IRA’s provisions is critical because it represents a paradigm shift in how insulin is priced and accessed in the public sector. The law also includes a provision extending enhanced subsidies for Affordable Care Act (ACA) marketplace plans through 2025, which indirectly helps many non-Medicare patients with diabetes afford both insurance and medications.

Other Federal Initiatives and Proposed Legislation

Beyond the IRA, several other federal actions and proposals are shaping diabetes policy. The Medicare Diabetes Prevention Program (MDPP) continues to expand, with updated billing codes and reimbursement rates for eligible beneficiaries. In 2023, the Centers for Medicare & Medicaid Services (CMS) finalized rules to expand coverage of continuous glucose monitors (CGMs) to a broader population of Medicare beneficiaries, including those using multiple daily injections. This change eliminates the previous requirement that beneficiaries must be on intensive insulin therapy (three or more injections per day) to qualify for CGM coverage.

At the congressional level, bills such as the Affordable Insulin Now Act (which would extend the $35 copay cap to private insurance) and the Diabetes Care Improvement Act (designed to boost funding for diabetes self-management education and support — DSMES) have been introduced but not yet passed. CDE candidates should monitor the progress of these bills, as their passage would have immediate implications for clinical practice and patient counseling. A reliable source for tracking federal legislation is the Congress.gov website.

State-Level Policy Innovations

While federal laws set national standards, states have been laboratories for diabetes policy innovation, particularly around insulin affordability, insurance coverage, and access to education. More than 30 states have enacted laws to cap insulin copays for state-regulated insurance plans, and many have also addressed prior authorization barriers. CDE candidates should be familiar with the policy approaches in their own state, as well as notable examples from around the country.

Insulin Affordability Laws

California and New York have passed laws requiring insurance plans to cover at least one form of insulin without prior authorization. Colorado was the first state to impose a copay cap on insulin (at $100 per month) back in 2019, and since then, states like Michigan, Washington, and Illinois have implemented caps between $25 and $35 per month for insured patients. Importantly, these state-level caps apply only to plans regulated by the state (i.e., fully insured employer-based plans and individual market plans), not to self-funded employer plans, which are governed by federal law (ERISA). This nuance is a key distinction that CDE candidates should understand because it affects how they advise patients about insulin costs based on their insurance type.

State-Funded Insulin Assistance Programs

Some states have gone beyond copay caps by creating state-funded insulin assistance programs. For example, Maine and Minnesota have established programs that provide free or low-cost insulin to uninsured and underinsured residents. These programs often rely on partnerships with pharmaceutical companies and nonprofit pharmacies. CDE educators should be aware of such resources in their states to refer patients who struggle with affordability. The Kaiser Family Foundation offers a comprehensive tracker of state insulin policies.

Coverage of Diabetes Prevention and Education Programs

State Medicaid programs have also expanded coverage for DSMES and medical nutrition therapy. As of 2024, over 40 state Medicaid programs cover DSMES, and many now reimburse for telehealth-delivered education sessions. Some states, like Oregon and Massachusetts, have mandated that insurance plans cover at least two hours of continuous glucose monitor training and diabetes self-management education per year without cost-sharing. These state-specific mandates directly impact the work of diabetes educators, as they create new opportunities for patient engagement and reimbursement.

Implications for the CDE Exam

Understanding these legislative changes is essential for the CDE exam, as they influence clinical practice and patient education. The CDE exam, administered by the National Certification Board for Diabetes Educators (NCBDE), tests candidates on a broad range of topics, including the psychosocial, behavioral, and systems-level factors that affect diabetes care. Policy knowledge falls under the domain of “systems and population health,” and candidates can expect questions that require them to apply current laws to patient scenarios.

Alignment with the CDE Exam Content Outline

The NCBDE CDE Exam Content Outline includes domains such as “Diabetes Self-Management Education and Support” and “Population Health and Advocacy.” Within these domains, specific competencies include:

  • Identifying barriers to diabetes care, including financial and access barriers.
  • Understanding the role of public policy in shaping diabetes care delivery.
  • Applying knowledge of insurance coverage and reimbursement to help patients access medications and supplies.
  • Advocating for patients within healthcare systems and communities.

These competencies directly map to the legislative and policy topics discussed above. For instance, a test question might describe a Medicare beneficiary who is struggling to afford insulin and ask the candidate to identify the appropriate copay cap or recommend a patient assistance program. Another question might present a scenario involving a pregnant patient with type 2 diabetes and require the candidate to discuss how state Medicaid coverage affects access to DSMES.

Key Knowledge Areas to Master for the Exam

  • Medicare and Medicaid coverage changes: Insulin copay caps ($35/month Part D), CGM coverage expansion, MDPP reimbursement structures, and the differences between Part D and Part B.
  • State-specific legislation and programs: Candidates should review the policies of the state(s) where they practice, but also understand the general landscape of insulin caps, prior authorization reforms, and state-funded assistance programs.
  • Impact of legislation on patient education and support services: Laws that expand coverage for DSMES and telehealth create opportunities for CDE educators; candidates should know how to leverage these policies in their practice.
  • Advocacy frameworks: The CDE exam may include questions about how to advocate for policy change at the local, state, or national level. Understanding the roles of organizations like the American Diabetes Association (ADA) and the Association of Diabetes Care & Education Specialists (ADCES) in policy advocacy is beneficial.

The policy landscape is continuously evolving. Several emerging trends are likely to impact diabetes care in the coming years and may appear on future CDE exams. CDE candidates should stay abreast of these developments to provide the most current information to patients.

Telehealth and Remote Monitoring

The COVID-19 pandemic permanently changed healthcare delivery. The Consolidated Appropriations Act of 2023 extended many telehealth flexibilities through December 2024, including the ability to provide DSMES via telehealth without geographic restrictions. CMS has proposed making several of these flexibilities permanent for Medicare. Many private insurers and state Medicaid programs have also expanded coverage for remote patient monitoring of blood glucose levels. These changes allow CDE educators to reach more patients, particularly those in rural or underserved areas, and to support ongoing management between in-person visits.

Biosimilar Insulins and Pricing Reform

The introduction of biosimilar insulins (e.g., Semglee, followed by other interchangeable biosimilars) has increased competition and lowered list prices for insulin. In 2023, several manufacturers announced price cuts for popular insulin brands, partly in response to public and policy pressure. The IRA’s rebate provisions also discourage manufacturers from raising list prices faster than inflation. CDE educators should understand the difference between biosimilar and reference insulins, how substitution works at the pharmacy, and how pricing changes affect patient access. This knowledge is both clinically relevant and policy-focused.

Continuous Glucose Monitor (CGM) Access and Equity

Medicare’s expansion of CGM coverage to all individuals with diabetes who are on insulin (regardless of injection frequency) is a major step forward. However, disparities remain: Medicaid coverage for CGMs varies widely by state, and many patients face high cost-sharing even when covered. Policy advocates are pushing for federal legislation to standardize CGM coverage across all payers and to expand access to non-insulin-using patients with diabetes (e.g., those with gestational diabetes or type 2 diabetes not on insulin). The CDE exam is likely to include questions about CGM coverage criteria and how educators can help patients obtain these devices.

The Role of the Diabetes Educator in Policy Advocacy

The CDE exam emphasizes not only clinical knowledge but also the role of the diabetes educator as an advocate for patients and the profession. Staying informed about legislation and policy is the first step; educators are encouraged to take action by:

  • Engaging with professional organizations: The ADCES Advocacy page provides resources for contacting lawmakers, writing letters, and participating in advocacy days.
  • Educating colleagues and patients: Many patients are unaware of their rights regarding insulin copay caps or CGM coverage. Educators can create handouts, discuss policy during education sessions, and refer patients to assistance programs.
  • Participating in research and policy development: CDE-credentialed professionals can serve on advisory boards, comment on proposed rules (e.g., CMS rulemaking), or collaborate with state health departments to shape diabetes programs.

The CDE exam may include situational questions that test a candidate’s ability to advocate for a patient who is denied coverage for a necessary medication or device. Understanding the policy levers — such as filing an appeal, using a patient assistance program, or contacting a state insurance commissioner — is part of the educator’s toolkit.

Conclusion

Diabetes legislation and policy are dynamic fields that directly influence every aspect of diabetes care, from medication affordability to insurance coverage and education access. For CDE candidates, mastering these topics is not just about passing an exam — it is about becoming a more effective clinician and advocate. By staying current with federal laws like the Inflation Reduction Act, state-level innovations, and emerging trends such as telehealth and biosimilar insulins, future Certified Diabetes Educators can empower their patients to navigate the system and achieve better health outcomes. Regular review of resources from the NCBDE, ADCES, Kaiser Family Foundation, and state health departments will ensure that your knowledge remains fresh and actionable.
