Unlocking CGM Access for Everyone—Diabetes Not Required

Navigating Your Path to Continuous Glucose Monitoring
How can I get a CGM is one of the most common questions we hear from people interested in tracking their glucose levels. Here's a quick answer:
Quick Guide: How to Get a CGM
- With a prescription (traditional route):
- Consult with your healthcare provider
- Get a prescription
- Verify insurance coverage and prior authorization
Order through pharmacy or DME supplier
Without a prescription (newer options):
- Purchase an over-the-counter CGM like Abbott's Stelo
- Sign up for a health program that offers CGM access
- Order directly from manufacturers' websites
A continuous glucose monitor (CGM) is a wearable device that tracks your glucose levels day and night, providing real-time data without the need for constant finger pricks. Once limited to people with type 1 diabetes, CGMs have become increasingly accessible to those with type 2 diabetes, prediabetes, and even health-conscious individuals without diabetes.
"Not monitoring blood glucose is like trying to fly an airplane with a blindfold on," as one healthcare provider puts it. CGMs remove that blindfold, giving you a continuous picture of how your body responds to food, exercise, stress, and sleep.
Whether you're managing diabetes or simply want to optimize your health, understanding how to access a CGM is your first step toward better glucose awareness. At ProMed DME, we've helped thousands of patients steer the sometimes confusing process of obtaining these valuable devices.
The good news? Recent FDA approvals have made CGMs more accessible than ever before, with both prescription and over-the-counter options now available. In this guide, we'll walk you through all the pathways to getting your own CGM.
What Is a Continuous Glucose Monitor and Who Can Benefit?
Think of a continuous glucose monitor as your body's personal glucose storyteller. Unlike traditional fingerstick meters that give you occasional snapshots, a CGM is a small wearable device that continuously reads glucose levels from the fluid surrounding your cells (interstitial fluid). It's like upgrading from a photo album to a full-length movie of your glucose patterns – capturing readings every few minutes and delivering up to 288 data points daily.
This wealth of information doesn't just tell you where your glucose is right now – it reveals where it's headed and how quickly it's changing. Those patterns and trends would remain invisible with just a few fingersticks a day.
"My CGM showed me that my morning coffee was causing glucose spikes I never knew about," shares Maria, one of our ProMed DME customers. "Now I add a protein shake, and my mornings feel much more balanced."
The world of CGM users has expanded dramatically in recent years. While once reserved primarily for type 1 diabetes, today's beneficiaries include:
People with type 1 diabetes who rely on CGMs as standard care, with life-saving alerts for dangerous lows. Type 2 diabetes patients gain exceptional insights, particularly those using insulin or at risk for hypoglycemia. Individuals with prediabetes can spot early warning signs and make targeted lifestyle changes before progression.
Pregnant women managing gestational diabetes appreciate the detailed monitoring, while athletes and fitness enthusiasts use glucose data to fine-tune performance and recovery. Even health-conscious individuals without diabetes are finding how personalized nutrition becomes when you can see your body's unique glucose responses.
How CGMs Work Inside Your Body
The magic happens just beneath your skin. Here's the simple science:
A tiny, flexible filament (thinner than a human hair) sits just under your skin, typically on your upper arm or abdomen. Getting it there is surprisingly easy – a spring-loaded applicator does the work in seconds with minimal discomfort.
This sensor contains special enzymes that react with glucose in your interstitial fluid, creating a tiny electrical current that corresponds to your glucose level. A transmitter attached to the sensor wirelessly beams this information to your smartphone or receiver, which displays your current reading, direction (rising or falling), and how quickly things are changing.
There is about a 5-15 minute lag between blood glucose and interstitial readings, which rarely matters for everyday use but is good to know during rapid changes.
Advantages Over Fingersticks
The leap from traditional fingersticks to CGM technology brings life-changing benefits:
Complete picture instead of isolated data points. Imagine seeing the entire roller coaster of your glucose day rather than just checking in at random moments. This comprehensive view reveals how your body responds to meals, exercise, stress, and sleep.
Trend information that shows not just where you are, but where you're headed. Those directional arrows allow you to take action before problems develop rather than reacting after the fact.
Dramatically fewer fingersticks since most modern CGMs are approved for making treatment decisions without confirmation pricks (though keeping a backup meter is always wise).
Peace of mind through customizable alerts. From warning you about overnight lows to catching rapid glucose changes, these notifications provide safety and confidence that fingersticks simply cannot match.
Pattern recognition through daily and weekly reports helps identify recurring issues. Maybe Tuesday's staff meeting always sends your glucose soaring, or that 3pm energy crash has a glucose component you never realized.
Time in range – the percentage of time spent within target glucose levels – has emerged as a more meaningful measure than the traditional A1C test alone.
Research published in the Journal of the American Medical Association demonstrates that CGM use typically reduces A1C levels by 0.4-0.5% while significantly decreasing time spent in dangerous low glucose states. For many users, this translates to fewer complications, better quality of life, and potentially reduced healthcare costs.
"Getting my CGM was like turning on the lights after years of fumbling in the dark," says James, who's been managing his diabetes with ProMed DME's support. "I finally understand what's happening in my body."
How can I get a CGM: Step-by-Step Overview
How can I get a CGM is a question with more answers today than ever before. The good news? Your path to continuous glucose monitoring has gotten simpler, with both traditional prescription routes and newer over-the-counter options now available.
The landscape of glucose monitoring changed dramatically in March 2023 when the FDA cleared the first over-the-counter CGM. This was a game-changer! For the first time, anyone interested in their metabolic health could legally purchase a CGM in the United States without needing a prescription or diabetes diagnosis.
Let's explore both pathways to help you find the right option for your situation.
Prescription vs. OTC Pathways
Understanding the differences between prescription and over-the-counter CGMs can help you decide which route makes the most sense for your needs:
Feature | Prescription CGMs | Over-the-Counter CGMs |
---|---|---|
FDA approval | For diabetes management | For general health monitoring |
Insurance coverage | Often covered with criteria | Not covered by insurance |
Cost | $0-75/month with insurance | $100-140/month out-of-pocket |
Models available | Multiple options (Dexcom, FreeStyle, etc.) | Limited (e.g., Abbott Stelo) |
Data features | Comprehensive alerts, sharing | Basic monitoring features |
Who can access | Requires doctor approval | Available to anyone |
Typical users | Diabetes patients | Health optimizers, prediabetes |
How can I get a CGM through my healthcare provider?
The prescription route might seem intimidating at first, but breaking it down into simple steps makes it manageable. Here's how to steer the process:
Start by having an honest conversation with your doctor about why you believe a CGM would benefit your health. Whether you're struggling with glucose control or simply want better insights, your healthcare provider needs to understand your motivation.
For insurance to cover your CGM, you'll typically need to meet specific criteria. Most plans require you to have type 1 diabetes, type 2 diabetes with intensive insulin therapy, or a documented history of problematic low blood sugar episodes. Your doctor will need to provide clinical documentation supporting your need.
Once your doctor writes the prescription, the prior authorization dance begins. This is where patience helps! Your doctor's office will submit paperwork showing your diagnosis, treatment plan, and why a CGM is medically necessary. At ProMed DME, we're quite familiar with this process and can often help guide you through it.
Before proceeding, it's worth calling your insurance company to verify which CGM brands they cover and what your expected out-of-pocket costs will be. Some plans cover certain brands but not others, and knowing this upfront can save headaches later.
With approval in hand, you can order your CGM through a DME supplier (like us at ProMed DME), your pharmacy, or directly from the manufacturer. We pride ourselves on making this step hassle-free by handling the paperwork, coordinating with your doctor, and delivering supplies right to your door with free shipping.
Don't skip training! Learning how to insert your sensor correctly, set up your device, and interpret your data will make a huge difference in your experience. Many people find the online training videos provided by manufacturers extremely helpful, and certified diabetes educators can offer personalized guidance.
Finally, establish a regular resupply schedule. Most sensors last 7-14 days, and transmitters need replacement every few months. With insurance coverage, these ongoing supplies are typically affordable, and setting up automatic reorders ensures you never run out.
How can I get a CGM over the counter or online?
If you don't have diabetes or don't qualify for insurance coverage, over-the-counter options provide a straightforward alternative:
The OTC route is perfect for those with prediabetes, type 2 diabetes not requiring insulin, or anyone curious about how food, exercise, and stress affect their glucose levels. No doctor's visit required!
As of 2023, your main OTC options include Abbott's Stelo (the first FDA-cleared over-the-counter CGM) and Lingo (compatible only with iOS devices in the US). Before purchasing, double-check that your smartphone is compatible—most systems require iOS 14.0+ for iPhones or Android 8.0+ for Android phones, with Bluetooth capability.
Buying an OTC CGM is refreshingly simple. You can purchase directly through the manufacturer's website, select pharmacies, or via certain health optimization programs. While not covered by insurance, these devices typically cost between $35-$75 for a 14-day sensor, with subscription options often available to reduce costs. And here's a helpful tip: many OTC CGMs qualify for HSA/FSA reimbursement, so you might be able to use pre-tax dollars.
Once your CGM arrives, you'll download the companion app, apply the sensor to the back of your upper arm (the process is surprisingly easy), and activate it through the app. Within an hour, you'll be seeing your glucose data in real-time.
Whether you choose the prescription or OTC route, a CGM can provide invaluable insights into how your body processes glucose. At ProMed DME, we're happy to help you steer either pathway to find the monitoring solution that best fits your health goals and budget.
Comparing Popular CGM Brands, Lifespan, and Costs
Choosing the right CGM can feel a bit like shopping for a new smartphone – there are several great options, each with their own unique features and price points. Let's walk through what's available to help you find your perfect match.
When I talk with patients about CGMs, I often compare it to choosing between different models of cars – they'll all get you where you need to go, but the ride and features can vary quite a bit! Here's what you need to know about today's most popular options:
The Dexcom G7 is often considered the premium option with its quick 30-minute warm-up time and highly accurate readings. It lasts 10 days per sensor and doesn't require fingerstick calibrations. The tradeoff? At around $500 monthly without insurance, it's one of the pricier options.
The FreeStyle Libre 3 offers excellent value with its 15-day sensor life (the longest on the market) and approachable price point of about $150 monthly. Its predecessor, the FreeStyle Libre 2, remains popular with a 14-day sensor life and similar features at a slightly lower cost.
If you're looking for something truly different, the Eversense system features an implantable sensor that lasts 90-180 days – imagine changing your sensor just 2-4 times per year instead of every couple weeks! This convenience comes with a higher price tag (around $533 monthly) and requires daily calibration.
For those exploring the over-the-counter route, Stelo offers a solid option at approximately $140 monthly with a 14-day wear time and no prescription needed.
What really sets these systems apart are features like:
- Accuracy levels: Lower MARD percentages indicate better accuracy (Dexcom G7 leads at 8.2%)
- Alert capabilities: Some systems warn you before you hit dangerous levels
- Sharing options: Dexcom allows up to 10 followers to view your data – perfect for parents or caregivers
- Physical profile: Some sensors are slimmer and more discreet than others
- Integration with other devices: Consider whether you need your CGM to work with an insulin pump
Research published in the National Library of Medicine shows that despite the upfront investment, CGMs often pay for themselves through reduced emergency visits and fewer complications over time. It's like investing in good tires for your car – it might sting at purchase, but saves you from costly problems down the road.
Insurance & HSA/FSA Tips to Save Money
Let's be honest – medical costs can add up quickly. Here are some insider tips to make your CGM more affordable:
If you're going the prescription route, understanding your insurance coverage is crucial. Medicare beneficiaries can get coverage through LCD 33822 if you have diabetes, use insulin at least three times daily (or use a pump), and have consulted with your provider. Most private insurance plans cover CGMs for type 1 diabetes, type 2 on intensive insulin therapy, or if you have documented hypoglycemia.
When your insurance initially denies coverage (which happens more often than you'd think), don't give up! Work with your healthcare provider to document medical necessity and appeal the decision. Sometimes a peer-to-peer review between your doctor and the insurance medical director can turn things around.
Pro tip: Check whether your plan covers CGMs under pharmacy or durable medical equipment benefits – there can be significant cost differences between the two.
For everyone, regardless of insurance status, most CGMs and supplies qualify for HSA/FSA reimbursement, allowing you to use pre-tax dollars. This alone can save you 20-30% depending on your tax bracket.
Many manufacturers offer patient assistance programs, starter kit discounts, or subscription services with lower per-sensor costs. Some patients extend sensor life beyond the approved duration (though this isn't officially recommended).
At ProMed DME, we've helped thousands of patients steer these waters. Our team specializes in verifying your coverage, handling those pesky prior authorizations, and finding the most cost-effective options for your unique situation. We believe that managing your health shouldn't require a finance degree!
How can I get a CGM is just the first part of your journey – finding the right one at the right price is equally important. With the right approach, continuous glucose monitoring can be both affordable and life-changing.
Setting Up, Using, and Maintaining Your First CGM
So you've finally got your CGM in hand—exciting! Now comes the fun part: getting it up and running so you can start seeing those glucose patterns. Let's walk through everything you need to know to have a smooth experience from day one.
First-Time Setup Checklist
Think of setting up your CGM as a little ritual—one that'll become second nature before you know it. First, gather everything you need: your sensor, transmitter (if it's separate), the applicator, alcohol wipes, and perhaps some skin prep products if you have sensitive skin.
Choosing where to place your sensor matters more than you might think. Most people prefer the back of the upper arm because it's out of the way yet easy to reach. Your abdomen works too, just stay about two inches away from your belly button. Avoid areas with scars, tattoos, or lots of hair—they can interfere with sensor adhesion and readings.
Before applying, wash your hands thoroughly (your mom would be proud!) and clean your chosen site with an alcohol wipe. Let it dry completely—this isn't just a suggestion, it's crucial for good adhesion. If you have sensitive skin, consider using a barrier wipe first.
When you're ready to apply, follow your specific manufacturer's instructions. Most modern sensors have made this incredibly simple with auto-applicators—just position, press a button, and you're done! Apply firm pressure afterward to make sure everything's secure.
If your transmitter isn't already built into the sensor, you'll need to snap it in place. Listen for that satisfying click that tells you it's properly connected.
Now comes the digital part: download your CGM's app, follow the pairing instructions, and enter any required serial numbers. Then comes the hardest part—waiting through the warm-up period! This ranges from 30 minutes for the Dexcom G7 to about an hour for the FreeStyle Libre 3.
Once you're activated, take a few minutes to set up your alerts. How can I get a CGM to work best for me? Personalized alerts are key! Consider setting your high alert around 180-250 mg/dL and your low alert around 70-80 mg/dL, but discuss these thresholds with your healthcare provider for personalized recommendations. Many people also set different alert levels for day versus night.
Adhesive Tips for Extended Wear
Let's be honest—keeping these little devices stuck to your body for 7-14 days can be challenging, especially if you're active or sweat a lot. Here are some tried-and-true tricks from CGM veterans:
Before applying your sensor, try using a liquid adhesive like Skin-Tac around (not directly under) where the sensor will sit. This creates a stronger bond with your skin. Many users swear by overlay patches specifically designed for CGMs—they go over your sensor like a protective blanket.
Timing matters too! Apply your sensor after showering but before bedtime. This gives the adhesive several hours to set while you're not moving around too much. And if you're heading to the pool or beach, a bit of waterproof medical tape in a "picture frame" around the edges works wonders.
Apps and Device Compatibility
Your smartphone is about to become your glucose-tracking best friend. Most modern CGMs connect via Bluetooth, but compatibility varies by system.
Before purchasing, always check the manufacturer's compatibility list. Generally, you'll need an iPhone 7 or newer running iOS 14+ for Apple users. Android compatibility is more variable, so definitely verify your specific model.
Many CGMs now offer smartwatch integration too—imagine glancing at your Apple Watch or Android Wear device to check your glucose! Just keep in mind that some systems, like Abbott's Lingo, currently only work with iOS devices in the US.
The family sharing features can be particularly valuable for parents monitoring children with diabetes or adults caring for elderly parents—just remember these typically require internet connectivity and separate app installation.
Troubleshooting and Side Effects
Even with perfect setup, you might encounter a few bumps along the way. Don't worry—most issues have simple solutions!
If you experience signal loss, first check that your transmitter is properly attached and within range of your phone. For sensor errors, follow the manufacturer's troubleshooting steps—sometimes you might need a replacement sensor (which manufacturers will often provide free of charge).
When your app crashes or connectivity issues arise, the classic IT advice applies: update your app, toggle Bluetooth off and on, or restart your phone.
Physical considerations matter too. Sensor readings lag behind blood glucose by 5-15 minutes, especially during rapid changes—this isn't a malfunction, just the nature of measuring interstitial fluid.
Ever woken up to an unexplained low reading? You might have experienced a "compression low"—sleeping on your sensor can temporarily restrict blood flow and cause false readings. Simply change position and wait for a new reading.
Skin irritation is another common concern. If you notice redness or itching, try hypoallergenic adhesives, barrier films, or different placement sites. At ProMed DME, we've helped many customers find solutions that work for their sensitive skin.
As for accuracy, be aware that readings may be less reliable during the first 24 hours after insertion. Dehydration can affect sensor accuracy too, as can high doses of certain medications like acetaminophen or vitamin C with some CGM models.
When should you double-check with a fingerstick? Any time your symptoms don't match your CGM readings or before making critical treatment decisions. Your traditional glucose meter remains an important backup tool.
Most manufacturers offer 24/7 technical support for troubleshooting, and at ProMed DME, our registered nurse is always available to help you resolve issues and get the most out of your CGM experience. We're just a phone call away when you need guidance—because we understand that new technology can sometimes feel overwhelming, but the benefits are absolutely worth it!
Frequently Asked Questions about CGM Access
Let's tackle some of the most common questions we hear from people looking to start their continuous glucose monitoring journey. These questions come up in almost every conversation we have with new CGM users!
Do I need a prescription for every CGM?
Not anymore! This is one of the biggest recent changes in the CGM world. While most CGMs still require a doctor's prescription, the FDA has recently cleared certain models for over-the-counter purchase.
If you're an adult who doesn't use insulin, you now have prescription-free options like Abbott's Stelo and Lingo systems. This is a game-changer for people interested in metabolic health who previously couldn't access this technology.
For the prescription-based options, you'll still need to see your healthcare provider for:- Dexcom G6 and G7- FreeStyle Libre 2 and 3 (prescription versions)- Medtronic Guardian Connect- Eversense implantable system
"The OTC approval has been for many of our customers who were curious about their glucose patterns but didn't qualify under traditional insurance criteria," notes our diabetes specialist at ProMed DME.
Will my insurance cover a CGM if I'm not on insulin?
This is where things get a bit more nuanced. Insurance coverage for CGMs has definitely expanded, but the criteria vary widely between plans.
For Medicare beneficiaries, you typically need to:- Have a diabetes diagnosis (type 1 or 2)- Use insulin at least 3 times daily or use an insulin pump- Show evidence of frequent blood glucose testing- Have regular diabetes management consultations with your provider
Private insurance sometimes offers more flexibility. You might qualify even without insulin therapy if you have:- A documented history of hypoglycemia- Wide glucose fluctuations that affect your health- Difficulty reaching your target A1C despite maximal oral medication- Other compelling medical reasons your doctor can document
The secret to success? Documentation is absolutely key. Work closely with your healthcare provider to thoroughly document why a CGM would be medically necessary for your specific situation. This might include:
"We've helped hundreds of customers steer the insurance approval process," shares our insurance specialist. "Sometimes it takes persistence, but we're here to help with the paperwork and appeals if needed."
If you're denied coverage initially, don't give up! You can appeal with additional documentation, request a peer-to-peer review between your doctor and the insurance company, or consider one of the new over-the-counter options.
How long do CGM sensors really last?
The official answer and the real-world answer sometimes differ here!
According to manufacturer guidelines, sensors last for their FDA-approved duration:- Dexcom G6/G7: 10 days- FreeStyle Libre 2: 14 days- FreeStyle Libre 3: 15 days- Medtronic Guardian: 7 days- Eversense: 90 or 180 days (implantable)
In the real world, many users find ways to extend sensor life beyond these official periods. While we can't officially recommend this practice (manufacturers don't support it, accuracy may decline, and it voids your warranty), it's a common topic in diabetes communities.
Safety first: If you ever experience unusual symptoms or your readings don't match how you feel, always confirm with a fingerstick test. Your health is worth more than a few extra days from a sensor!
Can I wear my CGM during exercise, swimming, or showering?
Yes, absolutely! Modern CGMs are designed to stay with you through your daily activities. They're water-resistant and built to withstand normal movement and moisture.
Most systems have these water-resistance ratings:- Dexcom G7: Water-resistant up to 2.4 meters for 24 hours- FreeStyle Libre 3: Water-resistant up to 1 meter for 30 minutes- Most other systems: Fine for showering and brief swimming
For marathon swimming sessions or intense workouts where you'll be sweating heavily, you might want to use additional adhesive products to keep your sensor secure. After swimming, gently pat (don't rub!) the sensor area dry.
"I'm a competitive swimmer and my CGM stays put through hours of training," one of our customers recently shared. "The key is good application technique and sometimes an extra adhesive patch."
What's the difference between real-time CGM and flash monitoring?
This distinction has blurred over time, but there are still some key differences to understand:
Real-time CGM systems (like Dexcom and Medtronic) automatically send glucose readings to your device without any action needed on your part. They offer continuous data transmission and automatic alerts when your glucose levels go too high or low.
Flash monitoring (like the original FreeStyle Libre) traditionally required you to actively scan the sensor with your device to see your readings. The earlier versions didn't offer automatic alerts.
However, newer versions like the Libre 2 and 3 have added real-time alert capabilities, making them function much more like traditional CGMs. The lines between these categories continue to blur as technology advances.
At ProMed DME, we're happy to walk you through the specific features of each system to find the one that best matches your lifestyle and needs. Our goal is to make your CGM journey as smooth and beneficial as possible!
Conclusión
The journey to continuous glucose monitoring has evolved dramatically in recent years. What was once a specialized medical tool available only to those with type 1 diabetes has transformed into an accessible health technology for a much wider audience. Whether you're managing diabetes, monitoring prediabetes, or simply curious about your metabolic health, there's now a CGM pathway that aligns with your specific situation.
How can I get a CGM isn't a question with a simple, one-size-fits-all answer anymore. The landscape now offers everything from fully-covered prescription devices to user-friendly over-the-counter systems, giving you unprecedented choice in how you track and understand your glucose patterns.
When we step back and look at the big picture, several important themes emerge:
First, multiple access pathways now exist for different needs and situations. The traditional prescription route still works wonderfully for many people, especially those with diagnosed diabetes. But the newer over-the-counter options and health optimization programs have opened doors for those who might not qualify for or prefer not to use the medical route.
Second, insurance coverage continues expanding to include more people. While criteria still vary between plans, the trend is moving toward greater accessibility as the benefits of continuous monitoring become increasingly clear.
Third, the emergence of OTC options provides valuable alternatives for those who don't meet prescription criteria or who prefer a more direct purchase path. These devices may offer slightly different features, but they still provide the core benefit of continuous glucose visibility.
Fourth, CGM technology keeps getting better with each generation. Today's sensors are smaller, more accurate, and last longer than their predecessors. The companion apps become more intuitive and feature-rich with each update.
Finally, proper support makes all the difference in your CGM experience. From initial setup to troubleshooting and maintenance, having knowledgeable guidance can transform your relationship with this technology.
