Managing blood sugar has come a long way from traditional finger-prick testing. Today, many people are turning to wearable technology like continuous glucose monitors (CGMs) for real-time insights and better control. If you’ve been researching options or wondering how to order a continuous glucose monitor online, here’s a clear breakdown of how they work, who they’re for, and how to get one.
What Is a Continuous Glucose Monitor (CGM)?
A continuous glucose monitor (CGM)—also called a continuous blood sugar monitor—is a wearable device that tracks glucose levels throughout the day and night.
No need to check your blood sugar manually.
What A Continuous Glucose Monitor Does
- Uses a small sensor inserted just under the skin
- Measures glucose in your interstitial fluid (the fluid between cells)
- Sends readings to a smartphone or receiver every few minutes
- Provides trends, alerts, and historical data
This means you can see how your glucose changes in real time—whether it’s rising after a meal or dropping overnight.
Most modern wearable continuous glucose monitors are small, discreet, and often worn on the arm or abdomen.
Who Are CGMs Best For?
CGMs are most commonly recommended for people who need close, consistent glucose monitoring.
- People with Type 1 diabetes
- People with Type 2 diabetes, especially those on insulin
- Individuals with frequent low blood sugar (hypoglycemia)
- Those who have trouble managing or stabilizing glucose levels
In many cases, CGMs are considered essential for people using insulin because they provide constant feedback and help prevent dangerous highs and lows.
That said, some newer options are expanding access, including CGMs designed for people not on insulin or those focused on metabolic health.
Can You Order a CGM Online?
Yes—there are now several ways to order a CGM online.
- Through manufacturer websites or pharmacy programs
- Via telehealth platforms that provide prescriptions
- Through subscription-based CGM programs
However, in most cases, a prescription is still required, especially if you want insurance coverage.
Some newer models (like certain over-the-counter systems in the U.S.) are starting to become available without a prescription, but access varies by region.
Does Insurance Cover Continuous Glucose Monitors?
Insurance coverage for CGMs has improved significantly—but it’s not universal.
- Many private insurance plans cover CGMs, especially for insulin-dependent patients
- Coverage often requires proof of medical necessity
- Some plans reimburse partially, while others cover most costs
In Canada, coverage varies widely by province and plan, but many private insurers and provincial programs now offer partial or full coverage for eligible patients.
That said, people without diabetes or without qualifying criteria may need to pay out of pocket.
Can You Get a CGM Through Medicaid?
In the U.S., Medicaid can cover CGMs, but eligibility rules are strict.
Common Coverage
- A diagnosis of diabetes
- Use of insulin (often multiple daily injections or an insulin pump)
- Documentation showing medical need
Medicaid programs vary by state, but many now include CGMs for eligible patients—especially those at higher risk of complications.
If you’re researching Medicaid continuous glucose monitor options, it’s important to check your specific state’s requirements or work with a healthcare provider to confirm eligibility.
How Much Do CGMs Cost?
Without insurance, CGMs can be expensive.
- Initial setup: often several hundred to over $1,000
- Ongoing monthly costs: roughly $135–$400+
- Sensors need regular replacement (every 7–14 days in most cases)
Costs can drop significantly with insurance, government programs, or manufacturer savings plans.
What Is the Best Wearable CGM?
There’s no single “best continuous glucose monitor” for everyone—the right choice depends on your needs, budget, and lifestyle. However, there are some popular and widely recommended options.
Dexcom (e.g., G7)
- Real-time continuous readings
- No fingerstick calibration (in most cases)
- Strong app integration and alerts
- Widely covered by insurance
FreeStyle Libre (Abbott)
- Often more affordable
- Flash-style monitoring (scan to read, though newer versions offer alerts)
- Slim, easy-to-wear arm sensor
Medtronic CGM Systems
- Often paired with insulin pumps
- Advanced automation features for insulin delivery
Implantable CGMs (e.g., Eversense)
- Long-lasting sensors (months to a year)
- Inserted under the skin by a healthcare provider
When evaluating the best CGM program, there are some things to consider.
- Accuracy and ease of use
- Wearability and comfort
- App features and alerts
- Cost and insurance coverage
- How often sensors need replacing
A continuous glucose monitor can be a game-changer for managing diabetes, offering real-time insights that help reduce complications and improve quality of life. Whether you’re looking to get a continuous glucose monitor, explore insurance options, or compare the best wearable CGMs, the key is finding a solution that fits your medical needs and daily routine.
If you’re considering a CGM, the next step is usually speaking with a healthcare provider—especially if you want to access insurance or Medicaid coverage.
