Guidelines / Policy
The 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 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.
Learn MoreThe Centers for Medicare and Medicaid Services (CMS) expanded CGM access to beneficiaries on basal-only insulin or those with a history of level two or three hypoglycemia. Although the Local Coverage Determination (LCD) was originally anticipated to be implemented in July, CMS expanded access to CGM on April 16, 2023. This new coverage policy is aligned with consensus guidelines from the ADA and AACE, which recommend CGM for all patients on insulin at the outset of diagnosis. The new LCD, which was proposed in 2022, also removes the term “daily” as a descriptor for insulin to account for potential FDA approval of weekly insulins in the future.
Learn MoreThe 2023 Standards of Medical Care in Diabetes found Grade A evidence supporting the use of RT-CGM in adults with T1D or T2D on intensive insulin therapy and in adults with T2D on basal insulin. The American Diabetes Association (ADA) found Grade B evidence supporting the use of RT-CGM in children and adolescents with T1D on intensive insulin therapy and Grade E evidence for use of RT-CGM in children and adolescents with T2D on intensive insulin therapy. When used as an adjunct to pre- and postprandial BGM, RT-CGM can help to achieve HbA1c targets in pregnant patients with diabetes (Grade B). Based on input from experts, the ADA recommends continued access to RT-CGM through third party payers to people who have been using this technology.

Learn MoreEffective January 1, 2023, UnitedHealthcare (UHC) is making selected continuous glucose monitoring (CGM) devices and sensors available to Medicare Advantage members at the pharmacy point-of-sale (POS). The systems affected by this change in policy include the Dexcom G6 as well as the FreeStyle Libre 2 and 14-day versions. CGMs were previously only available to UHC Medicare Advantage members through national durable medical equipment (DME) vendors. While availability through DME vendors will remain in place, the plan sought to improve access to CGMs for members by expanding to the pharmacy POS. Managed care decision makers should take note of this change in policy as an example of how national payers are leveraging the pharmacy channel as a means of enhancing coverage and member access to beneficial diabetes technologies.
Learn MoreReal-time continuous glucose monitoring (RT-CGM) remains a key technologic advancement recommended for integration into the management of diabetes according to the American Diabetes Association (ADA) Standards of Care (SOC) 2022. ADA assigned Grade A evidence to the recommendation that RT-CGM be offered for diabetes management in adults with diabetes on multiple daily injections (MDI) of insulin or continuous subcutaneous insulin infusion (CSII). Similarly, the ADA assigned Grade A evidence to the recommendation that RT- CGM be used for diabetes management in adults with diabetes on basal insulin. ADA’s criteria for a Grade A designation is defined as clear evidence from well-conducted, generalizable randomized controlled trials that are adequately powered.

Learn MoreAccording to the 2022 American Association of Clinical Endocrinology (AACE) Clinical Practice Guideline, CGM is recommended for all persons with T1D, regardless of insulin delivery system, to improve A1C levels and to reduce the risk for hypoglycemia and DKA. The updated guideline likewise recommends CGM for those with T2D who are treated with insulin therapy, or who have high risk for hypoglycemia and/or who have hypoglycemia unawareness. These recommendations are Grade A—indicating the highest strength made by the AACE—and are supported by the best evidence level available, based on data from randomized controlled trials. Managed care and payer professionals should take note of this latest guideline as part of the growing body of consensus recommendations supporting the coverage of CGM in a broader population of members with diabetes.

The National Committee for Quality Assurance (NCQA) is revising its Healthcare Effectiveness Data and Information Set (HEDIS) standardized measures assessing plan performance for 2023. Notably, the 2023 dataset will include a new measure related to diabetes management: the risk-adjusted ratio of observed to expected emergency department visits for hypoglycemia among older adults (aged ≥67 years) with diabetes.
This measure reflects a key component of health plan quality pertaining to the management of diabetes, since older adults are more likely to experience severe hypoglycemia, potentially leading to several adverse outcomes: fall-related events and fractures, increased risk of cardiovascular events, and cognitive decline. Similarly, prevailing clinical practice guidelines for the treatment of older adults with diabetes emphasize the prevention of hypoglycemia as an important outcome. The new HEDIS measure provides an opportunity for health plans to identify older members with diabetes who are at highest risk of hypoglycemia and implement preventive interventions and more intensive management.
