The Ohio Diabetes Quality Improvement Project (QIP), focused on multisector collaborative approaches, reduced the percentage of patients with A1c >9% from 25% to 20% over two years. In response to barriers voiced by providers and patients, Medicaid payers added coverage for diabetes self-management education and removed prior authorization requirements for continuous glucose monitoring (CGM) within select populations. These efforts enhanced equity to Medicaid enrollees by making it easier to obtain and afford diabetes management supplies and resources.
Learn MoreThe recently issued 2025 ADA Standards of Care offered new guidance supporting CGM use in broader patient populations, the application of CGM metrics in achieving glycemic goals, and the integration of CGM with other diabetes technologies at diagnosis. Specifically, the 2025 Standards of Care recommend considering the use of CGM in adults with T2D NIT to achieve and maintain individualized glycemic goals. Reasserting the clinical value of CGM in type 1 diabetes in pregnancy, the ADA added that CGM may also be beneficial for gestational diabetes and T2D in pregnancy in the 2025 update. ADA also expanded their recommendation for CGM use in individuals with diabetes on any insulin therapy to include youths as well as adults. While previous versions of the Standards of Care stated that CGM metrics should not be used as a substitute for BGM, the 2025 update notes that CGM metrics can be used in conjunction with blood glucose monitoring to achieve glycemic goals. Highlighting the importance of early intervention, the ADA also recommends initiation of CGM, continuous subcutaneous insulin infusion, and automated insulin delivery at diagnosis, depending on a person’s or caregiver’s needs and preferences. These updates are relevant to managed care and payer decision makers in the development of clinically appropriate coverage policies that enhance access to CGM in broader patient populations.

Learn MoreA retrospective observational study using Aetna administrative claims data showed that CGM use was associated with clinically meaningful improvements in A1c and reduced health care resource utilization. The study, published in the Journal of Managed Care and Specialty Pharmacy, looked at a cohort of fully insured commercial and Medicare Advantage beneficiaries with diabetes and coverage for medical and pharmacy benefits. Data from 7,336 patients (74% T2D, mean age 57 years, 42% Medicare-insured, 54% male, 56% White) showed a significant improvement in A1c after CGM initiation (-0.7%, P<0.0001), including a -0.9% change in the T2D not on insulin group (n = 264). For the overall cohort, the number of patients with diabetes-related hospitalizations and emergency department visits decreased significantly by 67% and 40%, respectively (P<0.0001 for both). This real-world analysis suggests a potential for population-level clinical and economic benefits with CGM in a managed care setting, particularly among patients not using insulin.
Learn MoreClinical practice guidelines endorse the use of CGM, and CMS recently expanded coverage for this technological intervention. However, disparities due to racial/ethnic bias, insurance coverage, and healthcare literacy present barriers to equitable diabetes care and access to CGM. Data show that members of minority populations, those with lower socioeconomic status and those without private insurance are disproportionately affected by diabetes and have lower rates of CGM use. This article, published in Managed Healthcare Executive, notes that payers should place greater emphasis on expanding patient education programs. In addition, further action must be taken to inform patients and to increase adoption and dissemination of new diabetes care technology. In addition to enhancing provider knowledge of CGM and its role in optimal patient care, managed care and payer professionals are tasked with ensuring that unnecessary barriers do not exist in current coverage policies.
In an accompanying video series, Estay Greene, PharmD, MBA, provides insights on ways to improve the care of patients with diabetes from the payer persepective, with a focus on data supporting the use of CGM. Diana Isaacs, PharmD, BCPS, BC-ADM, BCACP, CDCES, FADCES, FCCP, and David Hines also share their perspectives on social determinants of health in diabetes management and overcoming disparities in care with appropriate use of CGM.

A poster presented at the Academy of Managed Care Pharmacy’s (AMCP) annual meeting in New Orleans, LA, shared data from a health initiative by Metro Nashville Public Schools. The employer provided CGM devices as a pharmacy benefit without prior authorization. This policy change led to a two-fold increase in CGM utilization among employees aged 18 to 64 years with T1D and T2D regardless of treatment regimen. The retrospective analysis, covering 184 participants, showed significant improvements in glycemic control associated with CGM use. Specifically, average A1c decreased from 8.7% to 7.9% and from 7.6% to 6.8% among those with T2D treated with insulin and not-treated with insulin, respectively. Additionally, CGM use resulted in a significant improvement in the proportion of individuals meeting the HEDIS and ADA HbA1c targets of <8.0% and <7.0%, respectively. These results underscore the potential benefits of CGM for improving diabetes management through streamlined health care payer and purchaser coverage.
Learn MoreThe poster outlines best practices for health plan coverage and access to Continuous Glucose Monitoring (CGM) for diabetes management, emphasizing the technology’s transformative impact on care. It recommends aligning coverage criteria with current medical evidence, enhancing utilization oversight, and improving access for underserved populations. Strategies include offering CGM under pharmacy benefits, educating healthcare providers and patients, and developing support systems for at-risk groups. The best practices, derived from expert interviews, a national survey, and a workshop, aim to assist health plan decision makers in optimizing diabetes outcomes and managing healthcare costs efficiently.
Learn MoreA retrospective cohort study published in JAMA Network Open showed that CGM use was associated with lower odds of developing diabetic retinopathy (DR) and proliferative diabetic retinopathy (PDR). Among 550 adults with type 1 diabetes (T1D) included in the analysis, 62.7% patients used CGM, 58.2% used an insulin pump, and 47.5% used both. After adjusting for age, sex, race and ethnicity, diabetes duration, microvascular and macrovascular complications, insurance type, and mean HbA1c, CGM was associated with lower odds of DR (odds ratio [OR], 0.52; 95% CI, 0.32-0.84; P=0.008) and PDR (OR, 0.42; 95% CI, 0.23-0.75; P =0.004), compared with no CGM use. These findings show that CGM can be beneficial preventing DR—the leading cause of blindness among adults in the United States—even in individuals with well managed T1D.

Learn MoreThe ADA Standards of Care include all of of the organization’s current clinical practice recommendations and are intended to provide clinicians, patients, researchers, payers, and others stakeholders with best practices in diabetes management, general treatment goals, and tools to evaluate the quality of care. The recommendations are based on an extensive review of the clinical diabetes literature, supplemented with input from ADA staff and the medical community at large. These comprehensive guidelines are updated annually, or more frequently online if new evidence or regulatory changes merit immediate incorporation In alignment with previous versions of the ADA Standards of Care, the 2024 update highlights the clinical benefit of CGM across a wide range of patient types based on a growing body of evidence.
