In-store pharmacies

When visiting an in-store pharmacy, it is essential to ensure that the specific CGM device you are looking for is in stock. Calling ahead or checking the pharmacy's website for inventory updates can save you a trip. Additionally, some CGM devices may require a prescription, so be sure to have the necessary documentation with you when making your purchase.

Another benefit of purchasing from an in-store pharmacy is the convenience of immediate product availability. Unlike online orders, which may take days to arrive, you can walk out of the pharmacy with your CGM device in hand. This is especially advantageous for those who need to start monitoring their glucose levels right away or are looking for a replacement device.

Cost and insurance coverage

The cost of a CGM device varies depending on the brand and model. Without insurance, a CGM system can cost anywhere from less than $2,000 to about $7,000 per year. The average yearly cost for a CGM system is estimated to be $1,200 to $3,600.

For example, the Dexcom G6 system costs around $7,000 annually without insurance, whereas the FreeStyle Libre systems cost about $2,000 per year. The FreeStyle Libre 3 system works only with smart devices, and with GoodRx coupons, you can expect to pay around $150 for two sensors, which last up to 14 days each. This means that you would need a minimum of 26 sensors per year, resulting in an annual cost of about $1,950 without insurance.

Most health insurance plans will cover CGM devices and their associated supplies if a prescription is provided. Abbott, the manufacturer of the FreeStyle Libre CGM systems, states that most people with commercial health insurance pay less than $40 per month out of pocket for sensors. For the Dexcom G6 system, a GoodRx partnership is available to help make the device more affordable, potentially saving you over $200 per month.

Medicare Part B covers self-testing equipment and supplies as durable medical equipment for people with diabetes who meet certain criteria. This includes CGM devices and their associated supplies, blood glucose meters, lancet devices, and lancets. Medicare Advantage plans offer coverage for CGM devices and supplies that match or exceed original Medicare. Additionally, most state Medicaid programs and Affordable Care Act (ACA) plans cover these devices, and they are also covered by Tricare for specific conditions.

Device accuracy

When it comes to device accuracy, there are a few things to keep in mind when choosing a continuous glucose monitor (CGM). Firstly, it's important to understand the two main types of CGMs: real-time and intermittently scanned. Real-time CGMs offer audible alarms that warn you if your blood sugar is getting too high or low, allowing you to make adjustments to prevent or mitigate the issue. They also continuously transmit data to a receiver or smartphone without the need for finger pricks. On the other hand, intermittently scanned CGMs require you to scan the device to get your glucose readings, and they do not offer alerts. While some CGMs require finger-stick confirmation for treatment decisions, others are factory-calibrated, eliminating the need for finger pricks altogether.

When considering device accuracy, it's worth noting that real-time CGMs are generally more accurate than intermittently scanned CGMs, and newer models are more accurate than older ones. Additionally, some CGMs can be used beyond their manufacturer-specified lifetime, which can improve their cost-effectiveness. However, the accuracy of CGMs can be impacted by factors such as the delay in the measurement technique and the lag time between changes in blood glucose and interstitial fluid glucose.

In terms of specific CGMs, the Dexcom G6 is known for its accuracy, transmitting data automatically every 5 minutes. The Freestyle Libre 2 also meets the highest accuracy standards over its 14-day wear period, providing accurate measurements every minute. However, some users have reported inaccurate readings with the Freestyle Libre. The Guardian Connect System by Medtronic provides detailed glucose data, including time in range data, but it is more expensive compared to other monitors. The Abbott Diabetes Care Freestyle Navigator I and the Medtronic Paradigm with Enlite sensor are also options, but they may not be as accurate as other CGMs.

When choosing a CGM, it's important to consider not only the device accuracy but also your personal needs and preferences. Consult with your doctor or diabetes educator to determine which CGM is right for you.

Safety information

Continuous glucose monitoring (CGM) devices are generally considered safe and effective for people with diabetes. However, there are some important safety considerations to keep in mind when using a CGM device.

Firstly, it is crucial to follow the instructions provided by the device manufacturer. Failure to use the CGM system as instructed may result in inaccurate readings, potentially leading to missed hypoglycemic or hyperglycemic events and incorrect treatment decisions. If you are experiencing symptoms that do not match the readings on your CGM, it is recommended to use a blood glucose meter to confirm your glucose levels and make treatment decisions.

Additionally, CGM devices have certain limitations. For example, the sensors need to be replaced regularly, typically every 7 to 14 days for disposable sensors, and up to 180 days for implantable sensors. Skin irritation or redness may occur at the insertion site due to the adhesive patches used to attach the sensor. It is advised to consult your doctor if you experience skin problems.

Furthermore, CGM devices should not be solely relied upon for making treatment decisions. They are intended to complement, not replace, standard blood glucose monitoring devices. Any therapy adjustments should be based on measurements obtained from standard blood glucose meters, especially if your symptoms do not match the CGM readings.

In the case of the Dexcom CGM system, it is important to note that the device is intended for adults and children (2 years and older) with diabetes who are on insulin or at risk for hypoglycemia. For those not on insulin, the Stelo Glucose Biosensor System, an over-the-counter CGM option, is available for individuals 18 years and older.

Lastly, always ensure you have a functioning mobile electronic device with the correct settings to receive sensor glucose information and alerts. If the mobile device is not set up or used correctly, you may not receive this critical information.
