CGM Eligibility Explained: Your Ticket to Easier Diabetes Management

How Do You Qualify for CGM? Core Requirements
Continuous Glucose Monitoring (CGM) technology has revolutionized diabetes management, offering real-time glucose readings without the hassle of multiple daily fingersticks. Instead of capturing just a moment in time, CGMs provide a continuous stream of data, showing trends and patterns that can transform how you understand and manage your diabetes. But the big question remains: how do you qualify for CGM coverage, and what steps do you need to take to get this life-changing technology?
At ProMed DME, we've helped thousands of patients steer the sometimes confusing world of CGM qualification and insurance coverage. In this comprehensive guide, we'll walk you through everything you need to know about qualifying for a CGM—from clinical guidelines to insurance requirements, documentation needs, and alternatives if you don't immediately qualify.
The path to CGM qualification typically begins with establishing medical necessity. While specific requirements vary by insurance provider, there are several core criteria that apply in most situations:
- Confirmed diabetes diagnosis (Type 1, Type 2, or gestational diabetes)
- Insulin therapy (multiple daily injections, basal insulin only, or insulin pump)
- History of problematic hypoglycemia (blood glucose <54 mg/dL)
- Demonstrated need for frequent glucose monitoring
- Willingness and ability to use the CGM system properly
The American Diabetes Association (ADA) Standards of Care recommend CGM for all adults with Type 1 diabetes and many with Type 2 diabetes, especially those using insulin. Medicare follows a five-point eligibility system, which we'll explore in more detail below.
Beyond these medical criteria, how do you qualify for CGM also depends on your personal readiness to use the technology. This includes factors like:
- Ability to wear a sensor continuously
- Willingness to respond to alerts and alarms
- Comfort with using smartphone apps or receivers
- Commitment to regular follow-up appointments
Personal CGM | Professional CGM |
---|---|
Patient-owned device | Clinic-owned device |
Continuous use | Short-term wear (7-14 days) |
Real-time data access | Blinded or retrospective data |
Requires insurance approval | Often easier to obtain |
Patient manages device | Provider manages device |
How do you qualify for CGM under general clinical guidelines?
Clinical guidelines for CGM qualification have expanded significantly in recent years as evidence supporting CGM benefits has grown. According to current ADA guidelines, CGM is recommended for:
- All people with Type 1 diabetes regardless of age
- Type 2 diabetes patients using multiple daily insulin injections
- Type 2 diabetes patients using basal insulin who experience frequent hypoglycemia or have high glucose variability
- Pregnant women with diabetes (any type) to help achieve tight glucose control
The evidence is particularly strong for patients who:- Experience frequent or severe hypoglycemia- Have hypoglycemia unawareness (inability to sense low blood sugar)- Need to lower their A1C but struggle with frequent lows- Show high glycemic variability despite intensive insulin management
Research has consistently shown that CGM use reduces A1C levels and time spent in hypoglycemia, even in the absence of other interventions. This growing evidence base has led to expanded coverage criteria across most insurance types.
How do you qualify for CGM if you have no insurance coverage?
If you don't have insurance coverage for CGM, several pathways still exist:
- Self-pay options: Monthly costs typically range from $100-$300 depending on the CGM brand and model.
- Manufacturer discount programs: Most CGM companies offer savings cards or patient assistance programs.
- Short-term professional CGM trials: These clinic-owned devices can provide valuable data to help qualify for personal CGM.
- Community health clinics: Some offer subsidized CGM programs for uninsured patients.
- Membership warehouse pharmacies: Often provide discounted cash prices on CGM supplies.
At ProMed DME, we work with patients to find the most cost-effective options when insurance coverage isn't available, including helping you apply for manufacturer assistance programs.
Medicare, Medicaid, and Private Insurance: Who Pays?
Figuring out who will cover your CGM can feel like solving a puzzle. Let's break down how do you qualify for CGM through different insurance types in a way that makes sense.
Medicare 2024 checklist for "how do you qualify for CGM"
Good news for Medicare beneficiaries! As of April 2023, Medicare has significantly expanded their CGM coverage. The 2024 requirements are much more accessible than in previous years.
To qualify under Medicare, you'll need a diabetes diagnosis (Type 1 or Type 2) and just ONE of the following: either insulin treatment of any kind (no minimum number of injections anymore!) or documented problematic low blood sugars (under 54 mg/dL or an event where you needed someone's help).
You'll also need a face-to-face visit or approved telehealth appointment within 6 months before your CGM order, proper training on how to use your device, and to use the CGM according to FDA guidelines.
What's wonderfully different in 2024? Medicare has dropped the old requirements for multiple daily fingersticks and doesn't distinguish between diabetes types anymore. This means many more people can access this life-changing technology.
One Medicare quirk to remember: you'll need a durable receiver device (the separate device that displays your readings) in addition to any smartphone app you might use. Medicare classifies this as Durable Medical Equipment (DME), which is how they justify coverage.
Don't forget to see your doctor at least every 6 months to maintain your coverage. These visits help document that you're actively using and benefiting from your CGM.
Medicaid rules & the most common state requirements
When it comes to Medicaid and CGM coverage, your zip code matters tremendously. Each state creates its own Medicaid rules, which can range from quite generous to quite restrictive.
Most states with good CGM coverage through Medicaid require a formal diabetes diagnosis, some form of insulin therapy, regular blood glucose testing (typically 3-4 fingersticks daily), and check-ins with your healthcare provider every few months. You'll likely need to renew your authorization every 6-12 months.
Some states add extra requirements like specific A1C ranges, documented severe low blood sugars, completion of diabetes education programs, or proof that you've been following your previous treatment plan.
At ProMed DME, we keep up with the constantly changing Medicaid requirements across all states we serve. We're happy to help you understand exactly what your state requires – just give us a call and we'll walk you through it!
Private insurance keys to approval
Private insurance plans often follow their own rulebooks for CGM coverage, though many have similar requirements to Medicare. Here's how to improve your chances of approval:
First, always check your specific plan's medical policy for CGM. This information is usually available through your online portal or by calling member services.
Second, ask your doctor to reference the American Diabetes Association Standards of Care in their documentation. These guidelines strongly support CGM use for many people with diabetes, and insurance companies respect these standards.
Third, many experienced providers use specific template language (sometimes called "smart phrases") that perfectly documents medical necessity. If your provider seems unsure about documentation, suggest they contact our team at ProMed DME for guidance.
Finally, determine whether your plan covers CGM as a pharmacy benefit or DME benefit. This affects where you'll get your supplies and potentially your out-of-pocket costs.
Most private insurers readily approve CGM for people with Type 1 diabetes using insulin, those with Type 2 diabetes on multiple daily insulin injections, anyone experiencing frequent low blood sugars, and people showing high glucose variability despite careful management.
Your doctor's detailed documentation makes all the difference. When they clearly explain why you specifically need CGM based on your unique situation, approval rates go way up. At ProMed DME, we're happy to work with your healthcare provider to ensure they include all the necessary details to maximize your chances of approval.
Documentation & Ordering Workflow Made Simple
Once you've determined that you qualify for CGM coverage, the next step is navigating the ordering process. Proper documentation is essential for insurance approval and ongoing coverage.
Step-by-step CGM ordering process
Getting your CGM doesn't have to be complicated. Think of it as a relay race where each person hands off the baton to the next until you cross the finish line with your CGM in hand.
It starts with your healthcare provider evaluating your diabetes management needs. They'll document why you need a CGM in your chart notes (this documentation is gold for insurance approval!) and write a detailed prescription specifying the brand, model, and quantities you need.
Next comes the insurance verification dance. Your benefits are checked to confirm CGM coverage, any required prior authorizations are submitted, and your out-of-pocket costs are calculated. This step can sometimes feel like waiting for water to boil, but it's crucial for avoiding surprise bills later.
Once verification is complete, your prescription zips off to a DME supplier like us at ProMed DME or to a pharmacy. We'll make sure all the required forms (like Certificates of Medical Necessity) are completed and attach all supporting documentation. Think of this as preparing your CGM's passport for its journey to you!
After insurance gives the green light, we spring into action. Your supplies are shipped directly to your door, along with initial training materials to help you get started. No need to make extra trips to the pharmacy or juggle multiple appointments.
The journey doesn't end with delivery, though. You'll need initial setup and training (which we're happy to help with), regular follow-up visits with your provider every 3-6 months, and a system for reordering supplies before you run out. At ProMed DME, we can even set up automatic reordering so you never have to worry about running low.
The specific ordering details vary slightly depending on which CGM brand you're prescribed:
With Dexcom G6/G7, you'll receive a receiver once (it lasts several years), sensors as a 3-month supply (typically 9 sensors), and transmitters every 3 months.
For the Freestyle Libre 2/3, you'll get a reader once (if you're not exclusively using your smartphone), and sensors as a 28-day supply (2 sensors). One nice thing about the Libre? No separate transmitter needed!
If you're prescribed the Medtronic Guardian, it's ordered through DME channels, is compatible with Medtronic insulin pumps, and requires specific ordering forms.
At ProMed DME, we handle this entire process for you—from verifying your insurance to delivering supplies right to your doorstep. We believe getting your diabetes supplies should be the easiest part of managing your condition.
Maintaining coverage every six months
Keeping your CGM coverage isn't a one-and-done deal—it requires a bit of ongoing maintenance. Most insurance plans require regular check-ins with your healthcare provider, which serve multiple important purposes.
These visits document that you're actively using your CGM (not letting it gather dust in a drawer), verify that it's actually helping improve your diabetes management, address any issues you might be having with the technology, and allow for adjustments to your treatment plan based on the CGM data.
For Medicare patients, these visits are non-negotiable and must happen at least every 6 months. The good news? They can be either in-person or via Medicare-approved telehealth visits. During these appointments, your provider should document your continued use of the CGM system, how you're using the data to adjust your treatment, any improvements in your diabetes management, and your ongoing need for the technology.
Missing these follow-up appointments could interrupt your coverage, so mark them on your calendar in bold! Think of them as maintenance checks for your diabetes care plan—just like you wouldn't skip oil changes for your car, don't skip these vital check-ins.
At ProMed DME, we often send friendly reminders when it's time for your follow-up appointment to help ensure your coverage continues without a hitch. Our goal is to make sure you never experience a gap in your diabetes management tools.
Options When You Don't (Yet) Qualify
If you don't immediately qualify for personal CGM coverage, don't lose heart. Several excellent alternatives can help you either bridge the gap or build a compelling case for future coverage.
Professional CGM as a bridge
Professional CGM can be your stepping stone when personal CGM coverage seems out of reach. Think of it as "trying before buying" – but with important clinical benefits.
With professional CGM, your healthcare provider's clinic owns the device, which you'll wear for a short period (typically 7-14 days). The data collected might be "blinded" (not visible to you during wear) or "unblinded" (allowing you to see readings). After your wear period, your provider analyzes the collected data to identify patterns and make treatment recommendations.
The beauty of professional CGM lies in its accessibility. Insurance companies often approve it more readily because it's billed under different codes (CPT 95250 for placement and CPT 95251 for interpretation). There's no long-term commitment required on your part, yet you gain powerful glucose pattern information that can transform your diabetes management.
Perhaps most importantly, professional CGM can help document glucose variability or hypoglycemia episodes that build a solid case for personal CGM coverage. We've seen countless patients at ProMed DME who initially used professional CGM and later qualified for personal devices after the data revealed important insights about their glucose patterns.
Professional CGM works particularly well if you're new to diabetes technology, face insurance restrictions, want a "test drive" before committing, or need solid documentation for coverage appeals. It's a win-win approach that provides clinical value while potentially opening doors to long-term CGM use.
Financial assistance & coupon programs
When insurance coverage isn't immediately available, don't assume CGM is out of reach. Several financial pathways can make this technology more affordable than you might expect.
Abbott, the maker of Freestyle Libre, offers a generous savings card program and free trial sensors to help you get started. If you're interested in Dexcom, their patient assistance program provides options for qualifying low-income patients who might otherwise struggle with costs. Medtronic users can explore the Medtronic Assurance program, which offers support for eligible patients facing financial challenges.
Beyond manufacturer programs, don't overlook discount options that can dramatically reduce out-of-pocket expenses. GoodRx often provides significant savings on CGM supplies at many pharmacies. Membership warehouse pharmacies frequently offer lower cash prices that might surprise you. Some patient assistance foundations even provide grants specifically for diabetes technology.
Want to dip your toe in the CGM waters before committing? Most manufacturers offer free trial programs lasting 10-14 days. Some forward-thinking clinics provide loaner devices for short-term use, and diabetes education programs may have demonstration units available to help you get comfortable with the technology.
At ProMed DME, we understand that navigating these financial assistance options can feel overwhelming. That's why our team is ready to help you explore every available program to find the most affordable path to CGM technology. We've helped countless patients find solutions that worked for their budget while improving their diabetes management.
According to research from the DiabetesWise tool, patients who explore all available discount and assistance programs can often reduce their CGM costs by 40-60% compared to standard retail prices. This can make the difference between accessing this life-changing technology or going without.
Remember – not qualifying for CGM coverage today doesn't mean you won't qualify tomorrow. The journey to CGM access is often more of a marathon than a sprint, and we're here to support you every step of the way.
Frequently Asked Questions About CGM Eligibility
Do I still need finger-sticks to qualify for Medicare CGM in 2024?
Good news! The days of pricking your fingers multiple times daily just to qualify for a CGM are officially behind us. As of April 16, 2023, Medicare eliminated the fingerstick requirement that previously created barriers for many people.
You no longer need to prove you're checking your blood sugar 4+ times daily. Instead, Medicare now covers CGM if you're using any type of insulin (regardless of how often you take it) OR if you have a history of problematic low blood sugars. This change has been life-changing for many of our Medicare patients who struggled with the previous requirements.
"When Medicare dropped the fingerstick requirement, it was like someone finally understood what we patients needed," one of our ProMed DME customers recently told us. "Now I can focus on actually managing my diabetes instead of jumping through hoops."
Can people with type 2 diabetes on basal insulin only get a CGM?
Absolutely yes! This represents one of the most significant expansions in CGM access in recent years.
Previously, if you were only taking a once-daily long-acting insulin like Lantus, Levemir, Toujeo, or Tresiba, many insurance companies would deny CGM coverage. The outdated thinking was that CGMs only benefited people taking multiple insulin shots throughout the day.
Today, Medicare and many private insurers recognize that everyone on insulin can benefit from CGM technology - whether you're taking multiple daily injections or just a bedtime basal dose. This change acknowledges what many diabetes specialists have known for years: seeing your glucose patterns helps all insulin users make better decisions, avoid lows, and improve their overall management.
One of our type 2 patients who uses only basal insulin shared: "Being able to see my overnight patterns completely changed how I manage my diabetes. I finded my glucose was dropping too low at 3 AM, something I never would have known without my CGM."
What documentation must accompany a CGM prior authorization?
When helping our patients get CGM coverage, we've found that proper documentation makes all the difference between a quick approval and a frustrating denial. Here's what your healthcare provider should include:
Your medical record should clearly document your diabetes diagnosis (including type and how long you've had it), your current medications (especially insulin), any history of low or high blood sugars, your A1C values, and a clear statement explaining why you need a CGM.
The prescription itself needs to specify the exact CGM brand and model, how many supplies you need and how often, and how long you'll need the CGM (typically written for 12 months).
For Medicare patients specifically, your record must show you've had a face-to-face visit within the last 6 months. This can be an in-person appointment or a Medicare-approved telehealth visit.
Some insurance plans also require a Certificate of Medical Necessity form, which your doctor completes to formally attest that the CGM is medically required for your care.
The most successful approvals happen when your provider directly addresses your specific insurance plan's requirements, often citing relevant American Diabetes Association guidelines. At ProMed DME, we often provide our patients with template language their doctors can use to increase approval chances.
How do you qualify for CGM often comes down to having the right documentation in place. Our team at ProMed DME works directly with your healthcare provider to ensure all necessary paperwork is properly completed before submission, significantly improving your chances of approval.
