Leveraging Diabetes Health Technology in Managed Care and Coverage Considerations for Real-Time Continuous Glucose Monitoring

Announcing a new white paper based on key findings from the Therapeutic CGM Health Care Stakeholder Summit held on November 7, 2019, in Washington, DC. The stakeholder panel included payer and employer leadership along with clinical experts in the field of endocrinology. The purpose was to gather input pertinent to the coverage and application of therapeutic continuous glucose monitoring (CGM) in managed care settings. Clinical evidence supporting the clinical and economic value of rtCGM was presented and the insights of these health care stakeholders were captured en route to formulating coverage policy recommendations for the future. This input is intended to advance the uptake and appropriate coverage of evidence-based health technology interventions by managed care organizations (MCOs) and various payers.

Clinical Implications of Real-time and Intermittently Scanned Continuous Glucose Monitoring

Source: Diabetes Care

Key Takeaways: CGM has emerged as a new standard of care for individuals with insulin-treated diabetes. Two types of CGM systems are now available: real-time CGM (rtCGM) and intermittently scanned (isCGM). rtCGM systems automatically transmit a continuous stream of glucose data to the user, provide alerts and active alarms, and transmit glucose data in real time to a smart phone and/or other display device. The current isCGM system provides the same type of data but requires the user to purposely scan the sensor to obtain information, and it does not have alerts and alarms. Both CGM technologies have significant advantages over self-monitoring of blood glucose; however, differences in the features and capabilities of the two approaches must be considered when guiding patient selection of the system that meets their individual needs.


Continuous Glucose Monitoring: An Emerging Standard of Care

Key Takeaway: The use of CGM is proven to reduce A1C, reduce time spent in hypo- and hyperglycemia and improve time in range (TIR) for Type 1 and Type 2 patients using intensive insulin, defined as multiple daily injections of insulin or getting insulin through an insulin pump.  This has resulted in guidelines and recommendations from professional societies such as the ADA recommending CGM as a standard of care for Type 1 and Type 2 patients using intensive insulin.  CGM is an important monitoring tool that is best accessed by providers and patients in the pharmacy channel.

Key Takeaway: Diabetes is a complex chronic disease that for some Type 1 and Type 2 patients requires the use of intensive insulin defined as 3 or more injections/day or insulin through a pump.  The adverse consequences of using insulin are severe and can result in a coma, seizure or even death which leads many patients and caregivers deciding to use less insulin as prescribed preventing achievement of glycemic goals.  Real-time CGM with alerts/alarms, remote monitoring and reporting can help patients use their insulin safely and effectively to achieve lower A1Cs, spend less time in hypo- and hyperglycemia and spend more time in range (TIR).  The benefits of CGM are seen when it is used to make diabetes treatment decisions such as insulin dosing, diet and lifestyle in a timely manner.  Accessing CGM devices via a pharmacy benefit allows patients to start CGM faster, stay safe while using insulin and engage pharmacists, providing additional support and interventions that have been shown to improve diabetes outcomes.


Clinical Targets for Continuous Glucose Monitoring Data Interpretation: Recommendations From the International Consensus on Time in Range

Source: Diabetes Care

Key Takeaway: Successful utilization of CGM technology in routine clinical practice remains relatively low due to a lack of clear and agreed-upon glycemic targets that both diabetes teams and people with diabetes can work toward.  In February 2019, the Advanced Technologies & Treatments for Diabetes (ATTD) Congress convened an international panel of physicians, researchers, and individuals with diabetes who are expert in CGM technologies to address this issue and established targets for time in range (TIR), time below range (TBR) and time above range (TAR).  These are metrics that only CGM can measure and overcome the limitations of metrics such as A1C which are reflective of a 3 month average of glycosylated hemoglobin and does not account for day to day glycemic variability or factors such as anemia which can skew A1C low.

Key Takeaway: Nationwide reimbursement of real-time CGM improved HbA1c, fear of hypoglycemia, and QOL as well as economic indicators including work absenteeism and hospital admissions for acute diabetes complications.


One-Year Time Analysis in an Academic Diabetes Clinic: Quantifying Our Burden

Source: Endocrine Practice

Key Takeaway: In an academic diabetes clinic, between-visit nonbillable time by nonphysicians is significant, costly, and most importantly, not sustainable. We clearly require a less burdensome mechanism to carry out evidence-based decisions for a condition that is a public health crisis.


 

Clinical Studies

Real Time CGM Studies

Effect of Continuous Glucose Monitoring on Glycemic Control in Adults with Type 1 Diabetes Using Insulin Injections – The DIAMOND Randomized Clinical Trial

Source: Journal of the American Medical Association

Key Takeaway: In the DIAMOND RCT, patients using multiple daily injections of insulin with type 1 diabetes who were randomly assigned to real-time CGM (rtCGM) had improved glycemic control vs. the SMBG group. This benefit was seen across patient groups regardless of baseline A1C, age, education level, or math ability. In addition, the rtCGM group spent 79% less time in nocturnal hypoglycemia, and also demonstrated a greater increase in hypoglycemic confidence and a greater decrease in diabetes distress vs. the SMBG group.


Baseline Glycated Hemoglobin Values Predict the Magnitude of Glycemic Improvement in Patients with Type 1 and Type 2 Diabetes: Subgroup Analyses from the DIAMOND Study Program

Source: Diabetes Technology & Therapeutics

Key Takeaway: Among the real-time CGM (rtCGM) users, the change in HbA1c was greatest in the highest HbA1c subgroup with similar decreases seen in both the T1D and T2D groups. Notably, adherence remained high in those with baseline HbA1c > 9% and the improvements seen were achieved without the need for additional medications. Thus, the costs of rtCGM in patients with high HbA1c may be offset by avoiding treatment intensification and the longer-term savings achieved by lowering HbA1c levels in poorly controlled diabetes populations.


Continuous Glucose Monitoring vs Conventional Therapy for Glycemic Control in Adults with Type 1 Diabetes Treated with Multiple Daily Insulin Injections – The GOLD Randomized Clinical Trial

Source: Journal of the American Medical Association

Key Takeaway: In the GOLD trial, glycemic control was improved with use of rtCGM compared with conventional treatment; however, increases in A1C and hypoglycemic events occurred when patients reverted back to SMBG during the crossover/washout period, suggesting that the effectiveness of CGM depends on uninterrupted use during treatment with MDI. Additionally, the study showed reductions in severe and nocturnal hypoglycemia as well as in glycemic variability and improved hypoglycemic confidence for rtCGM users.


Glycemic Outcomes in Adults With T1D Are Impacted More by Continuous Glucose Monitoring Than by Insulin Delivery Method: 3 Years of Follow-Up From the COMISAIR Study

Source: Diabetes Care

Key Takeaway: The COMISAIR study is the longest running real-world real-time CGM (rtCGM) study performed to date. In this study, the continuous use of rtCGM had a sustained and durable benefit with regards to glycemic control over a 3-year time period, with rtCGM being superior to self-monitoring of blood glucose in reducing A1C, hypoglycemia, and glycemic variability in individuals with type 1 diabetes regardless of their insulin delivery method.

Six-Month Randomized, Multicenter Trial of Closed-Loop Control in Type 1 Diabetes

Source: The New England Journal of Medicine 

Key Takeaway: This 6 month randomized trial showed use of a closed-loop system using the t:slim X2 insulin pump with Control-IQ Technology, (Tandem Diabetes Care) and a continuous glucose monitor (Dexcom G6, Dexcom) was safe and effective compared to sensor-augmented pump therapy (SAP). Participants in the closed-loop group achieved 70% time in range overall which meets the International Consensus Guidelines for people with diabetes. The closed-loop group also achieved significant improvements in hyperglycemia, HbA1c, mean glucose, and hypoglycemia (< 70 mg/dL < 54 mg/dL) as compared with the SAP group. Glycemic benefits were seen in the first month of the trial and were sustained over the entire 6-month period. Over 90% of participants said they trusted the device and found Control-IQ technology easy to use.

Key Takeaway: The ADA Standards of Medical Care in Diabetes provides the most authoritative and current guidelines for diabetes care. The recommendations are intended to provide clinicians, patients, researchers and payers with the components of diabetes care, general treatment goals, and tools to evaluate the quality of care. Following are ADA recommendations regarding CGM:

American Diabetes Association

rtCGM should be used continuously for maximal benefit. 

isCGM should be scanned frequently throughout the day (minimum of once every 8 hours)

CGM and T1D

  • Real-time CGM (rtCGM) and intermittently scanned CGM (isCGM) are useful to lower A1C and/or reduce hypoglycemia in adults who are not meeting glycemic targets, have hypoglycemia episodes, and/or unawareness (RT-CGM (A); IS-CGM (C))
  • rtCGM may be used to improve A1C levels and neonatal outcomes in pregnant women (A)
  • Should be considered in all children and adolescents to improve glucose control regardless of insulin delivery method (B)

CGM and T2D

  • Useful tool, when used in conjunction with insulin therapy, to lower A1C and/or reduce hypoglycemia in adults with T2D who are not meeting glycemic targets (B)

Level of Clinical Evidence: A = Clear evidence from well-conducted, generalizable randomized controlled trials that are adequately powered; B = Supportive evidence from well-conducted cohort studies; C = Supportive evidence from poorly controlled or uncontrolled studies

Advancing Glycemic Management in People with Diabetes

Source: The IQIVA Institute

About the report: The incorporation of time in range (TIR) metrics alongside HbA1c is expected to enhance the way in which diabetes is managed in the future, and subsequently, reduce the overall societal and economic burden. To assess the value of improving TIR from its current state to the minimum consensus target of 70% and 80% TIR, the IQVIA Core Diabetes Model was used to estimate cost reductions in complications and costs associated with improving TIR. Using this model, improvements in TIR were estimated to reduce the risk of developing diabetes-related complications resulting in a conservative reduction of $2.1-7 billion in costs over a 10-year period, based on the relationship between TIR and HbA1c. The addition of incrementally reducing hypoglycemic events in people with Type 1 Diabetes by 40% and improving TIR to 80% generated a total 10-year cost reduction of $6.7-9.7 billion. This reduction in costs represents a conservative estimate.

A Cost Offset Analysis (COA) Comparing Real-Time Continuous Glucose Monitoring (RT-CGM) With Intermittent Scanning Continuous Glucose Monitoring (IS-CGM) in Type 1 Diabetes (T1D) Subjects With Impaired Hypoglycemia Awareness in Eight Countries

Source: Value in Health. 2019: Volume 22 S572. doi: 10.1016/j.jval.2019.09

Key Takeaway: A recent RCT comparing an rt-CGM and is-CGM device demonstrated differences in %TIR over several glucose ranges allowing for projection of potential clinical outcomes. A COA was performed comparing these clinical cost offsets for rt-CGM and is-CGM in people with T1D (n=2,000) and impaired awareness of hypoglycemia (IAH; ~30% of people with T1D), applied to eight countries each over a one-year period. The demonstrated differences in %TIR spent at low, optimal, and high glucose ranges are likely to translate into significant clinical and economic benefits for rt-CGM compared with is-CGM.


Cost Offset Analysis (COA) Comparing Real-Time Continuous Glucose Monitoring (RT-CGM) With Self-Monitoring of Blood Glucose (SMBG) in People With Type 1 Diabetes in Eight Countries

CMS-1682R – Therapeutic CGM Category

Source: Centers for Medicare & Medicaid Services

Key Takeaway: Recognizing the value of CGM, and in response to the recent FDA approvals of CGM as a replacement for fingersticks, CMS created a benefit category for therapeutic CGMs, providing for coverage of these devices under the following conditions:

  1. The beneficiary has diabetes mellitus (Refer to the “ICD-10 Codes that are Covered” section of the LCD-related Policy Article for applicable diagnoses); and,
  2. The beneficiary has been using a BGM and performing frequent (four or more times a day) testing; and,
  3. The beneficiary is insulin-treated with multiple (three or more) daily injections of insulin or a Medicare-covered continuous subcutaneous insulin infusion (CSII) pump; and,
  4. The beneficiary’s insulin treatment regimen requires frequent adjustment by the beneficiary on the basis of BGM or CGM testing results; and,
  5. Within six (6) months prior to ordering the CGM, the treating practitioner has an in-person visit with the beneficiary to evaluate their diabetes control and determined that criteria (1-4) above are met; and,
  6. Every six (6) months following the initial prescription of the CGM, the treating practitioner has an in-person visit with the beneficiary to assess adherence to their CGM regimen and diabetes treatment plan.

Current Eligibility Requirements for CGM Coverage Are Harmful, Costly, and Unjustified

Source: Diabetes Technology and Therapeutics

Key Takeaway: There is growing and compelling evidence that CGM coverage should be offered to all patients who can benefit from this technology regardless of diabetes type and history of SMBG use. The current restrictions, which are based on outdated evidence and questionable assessments, are not supported in the literature. Moreover, they ignore the burden frequent SMBG places on individuals. Given the growing prevalence of diabetes, the persistent preponderance of individuals with suboptimal glycemic control, and the exorbitant and largely preventable cost of diabetes complications, opinion-based constraints should not continue to supplant evidence-based clinical management.
