Best Places To Buy Continuous Glucose Monitors

Continuous glucose monitoring (CGM) systems are small sensor-based systems that measure blood glucose levels in real-time throughout the day and night. CGM devices come in three parts: the sensor, the transmitter, and the receiver (usually a smartphone). The sensor is inserted just below the skin and worn for up to two weeks, eliminating the need for daily finger pricks. The transmitter continuously sends blood sugar readings to the receiver as often as every minute. This allows users to identify blood sugar trends and gauge the impact of food and physical activity on their blood sugar in real time, making it easier to manage diabetes. CGMs are available from various retailers, including Walgreens, Amazon, Diabetic Warehouse, and Advanced Diabetes Supply.

Local pharmacies

Finding the Right CGM

When visiting your local pharmacy, you'll find that CGM systems typically consist of a few basic components: sensors, a receiver or a compatible smart device, and sometimes a transmitter. The sensors are usually worn on the back of the arm or discreetly placed under the skin, allowing for continuous glucose monitoring without the need for frequent finger pricks.

Some popular brands available at pharmacies include Dexcom and FreeStyle Libre. The Dexcom G6 and G7 models are widely used and offer flexibility in terms of using a receiver or a smartphone to display data. The FreeStyle Libre 2 is another option that provides accurate glucose readings with a painless one-second scan, and it is suitable for adults and children with diabetes.

Cost Considerations

The cost of a CGM system can vary depending on the brand and your insurance coverage. Without insurance, a CGM system can range from less than $2,000 to about $7,000 per year. However, with insurance, the costs can be significantly reduced. For example, with commercial insurance, patients may pay between $0 to $75 per month for the FreeStyle Libre 2 sensors. Medicare may also cover the cost of CGM systems for those who qualify with a prescription.

To save money, consider using your smartphone as a receiver instead of purchasing a separate device. Additionally, look for pharmacy-specific discounts or coupons, such as the GoodRx coupons, which can help reduce the cost of popular brands.

Understanding Compatibility

When choosing a CGM system, it's important to ensure that the sensors, transmitters, and receivers are compatible with each other. For example, the Dexcom G6 requires a transmitter, while the newer Dexcom G7 works without one. The FreeStyle Libre 3 is designed to work only with smart devices, whereas the FreeStyle Libre 2 offers the option of using either a reader or a smartphone.

Pharmacy Recommendations

Your local pharmacist can be a valuable source of information and guidance when selecting a CGM system. They can help you understand the features and compatibility of different models, as well as advise you on any specific requirements or considerations based on your needs.

Additionally, your pharmacist can provide guidance on insurance coverage and payment options, ensuring that you get the best value for your purchase. They may also be able to direct you to any available discounts or coupons to make the CGM system more affordable.

In conclusion, local pharmacies offer a convenient and accessible way to purchase a CGM system. By understanding the different components, brands, and cost considerations, you can make an informed decision with the help of your pharmacist. Remember to also explore insurance options and discounts to make this life-changing technology more accessible.

Insurance coverage

Continuous glucose monitors (CGMs) are available with insurance coverage, but this depends on several factors, including the type of insurance, the state, and the insurance provider. Here is a detailed overview of insurance coverage for CGMs:

Commercial or Private Insurance

Commercial or private insurance plans often provide coverage for CGMs, but specific eligibility requirements must be met. These requirements vary widely between insurance providers and plans, so it is essential to review the specific plan details. In general, referencing treatment recommendations or standards from reputable societies, such as the American Diabetes Association (ADA), can be helpful in seeking authorization. The ADA Standards of Medical Care in Diabetes are updated regularly and can provide guidance on CGM coverage.

Medicare

Medicare may cover a CGM and related supplies if certain requirements are met. To qualify for Medicare coverage, individuals must:

• Have diabetes mellitus.
• Take insulin or have a history of problems with low blood sugar.
• Have a prescription for testing supplies and instructions on testing frequency.
• Have been trained or have a caregiver trained to use a CGM as prescribed.
• Make routine in-person or Medicare-approved telehealth visits with their doctor.

Medicare typically covers most CGMs, such as the Dexcom 6 and FreeStyle Libre, if they are determined to be therapeutic by a healthcare provider. Medicare Advantage plans, a specific type of Medicare plan, also generally cover diabetes monitoring devices.

Medicaid

Medicaid coverage for CGMs varies widely by state, and at least five states do not publish any coverage information. As of May 2023, 45 states and the District of Columbia offer some level of coverage for CGMs. However, there is no consistent policy governing who qualifies and the extent of coverage. States with expanded Medicaid services are more likely to provide coverage for CGMs.

Affordable Care Act (ACA)

Under the ACA, health insurance plans are mandated to cover essential health benefits, which include chronic disease management. While the ACA does not specifically require coverage of diabetes devices, most states mandate coverage of diabetes monitoring devices, which can include CGMs.

TRICARE

TRICARE is a healthcare program for military personnel and their families, and it may cover CGMs through pharmacy benefits or medical benefits. Glucometers, another type of diabetes monitoring device, are covered under medical benefits as durable medical equipment.

Other Options

If an individual's insurance plan does not cover CGMs, there are alternative options to consider:

• Health Savings Account (HSA): Individuals can use funds from an HSA to cover the cost of a CGM and related supplies not covered by their insurance plan. CGMs are classified as IRS-qualified medical expenses and are therefore eligible for reimbursement through an HSA.
• Financial Assistance Programs: Various financial assistance programs and discounts are available to help individuals access CGMs. These include patient assistance programs, copay reduction programs, and vouchers.
• State-Specific Programs: Some states have implemented initiatives to reduce out-of-pocket costs for diabetes supplies, including CGMs. For example, Connecticut has capped out-of-pocket expenses for diabetes supplies, including glucometers, at $100 per year for insured residents.

Cost

The cost of a continuous glucose monitor (CGM) can vary depending on the brand and the specific model. Without insurance, a CGM can cost anywhere from less than $2,000 to about $7,000 per year. The average yearly cost for a CGM is estimated to be between $1,200 and $3,600.

The Dexcom G6 and G7 are on the higher end of the price range. The Dexcom G6, which requires a receiver, costs about $7,000 annually without insurance. The Dexcom G7 costs at least $5,000 per year if you use your smartphone for readings and about $450 more if you need a receiver.

The Abbott FreeStyle Libre systems are more affordable than other CGMs. The FreeStyle Libre 3, for example, costs about $150 for two sensors (lasting 14 days each) without insurance. This would amount to about $1,950 per year for the sensors alone. Most commercially insured patients will pay between $0 to $75 per month for the FreeStyle Libre 2 system sensors.

The first over-the-counter CGM, the Dexcom Stelo, costs $89 per month or $99 for a one-time order of two sensors. This device is intended for people with Type 2 diabetes who do not take insulin.

In addition to the cost of the CGM device itself, users may also need to purchase adhesive skin patches, a blood glucose meter, lancets, and strips to calibrate the CGM. Smartphone apps are often available for free to connect to the CGM.

Accuracy

When it comes to accuracy, it's important to note that CGMs measure "interstitial" glucose, which is the glucose found in the fluid under the skin, rather than blood glucose. This can lead to discrepancies when comparing CGM readings to fingerstick glucose readings, especially when blood glucose levels are rapidly changing. Additionally, factors such as calibration frequency, environmental influences, and proper placement of the sensor can impact the accuracy of CGM readings.

To ensure accuracy, it is recommended to consult with a healthcare professional to determine the most suitable CGM for your needs and to follow the instructions for placement and maintenance carefully. Regular calibration, as recommended by the manufacturer, is also crucial for maintaining accuracy over time.

In terms of affordability, the Freestyle Libre 3 is a good option, offering accurate and reliable readings at a lower cost compared to other CGMs. It is also widely accepted by insurance providers. However, it is important to note that insurance coverage for CGMs can vary, so checking with your insurance provider is essential before making a purchase.

In summary, accuracy is a critical factor when choosing a CGM, and the Dexcom G6 is currently the most accurate device on the market. Other recommended options include the Freestyle Libre 3 for its accuracy and affordability, and the Eversense CGM System for its long sensor life. Consulting with a healthcare professional and properly maintaining your CGM can help ensure accurate and reliable readings.
