Does the VA Cover Continuous Glucose Monitors (CGM)?

The VA does cover continuous glucose monitors for eligible veterans, and the system has been expanding access in recent years. Veterans with insulin-treated diabetes, whether type 1 or type 2, can receive a CGM through their VA healthcare provider. But having coverage on paper and actually getting a device in your hands are not the same thing, and the gap between the two is wider than most veterans realize.

Who Qualifies for a CGM Through the VA

If you are enrolled in VA healthcare and managing diabetes with insulin, you are generally eligible for a CGM. This applies to both type 1 and type 2 diabetes. The VA treats CGMs as prosthetic devices, which means they are dispensed through the VA’s prosthetics service rather than a standard pharmacy prescription, and this distinction matters for how you actually obtain one.

To get the process started, you need a prescription from your VA provider. Your primary care physician or endocrinologist at the VA can initiate the order. In practice, the prescribing provider typically documents that you are on insulin therapy, and from there the prosthetics team handles ordering the device and ongoing sensor supplies. The VA currently offers devices from major CGM manufacturers, including the Dexcom and FreeStyle Libre product lines, though availability can vary by facility.

Unlike Medicare, which historically imposed requirements like multiple daily insulin injections and frequent fingerstick testing before approving a CGM, the VA system has somewhat more flexibility in how it evaluates clinical need. That said, your provider still needs to determine that a CGM is clinically appropriate for your situation. Veterans who experience frequent low blood sugar episodes, who have difficulty maintaining stable glucose levels, or who have trouble with traditional fingerstick monitoring are strong candidates. If you are on basal insulin alone and your blood sugar is reasonably well-controlled, the conversation may be different, but it is still worth having.

How CGMs Have Helped Veterans

The VA is one of the largest healthcare systems in the world, which means its data on CGM outcomes carries real weight. A large study within the Veterans Health Administration found that veterans who started using a CGM saw meaningful improvements compared to similar patients who did not. Among veterans with type 2 diabetes, average blood sugar levels dropped more in CGM users, and the risk of dangerously high blood sugar episodes fell by about 13%. The reduction in all-cause hospitalization was also significant: roughly 11% lower among CGM users with type 2 diabetes and 25% lower among those with type 1 diabetes.¹

For veterans with type 1 diabetes specifically, the risk of hypoglycemia dropped by about 31% after CGM initiation, which is a particularly important finding given how dangerous severe low blood sugar can be, especially in older adults or those living alone.¹

A separate study focused on veterans with type 2 diabetes found that how consistently someone actually wears the device makes a big difference. In the full group of veterans who received a CGM, the average improvement in long-term blood sugar control was modest. But among veterans who used the device consistently, the improvement was much larger, and those adherent users also lost an average of about eight pounds. The number of medical encounters related to diabetes complications also dropped for consistent users.²

The takeaway is straightforward: CGMs work, and they work better the more you use them. A device sitting in a drawer helps no one, but a veteran who wears the sensor regularly and engages with the data can see real health gains, fewer emergency visits, and potentially fewer medications over time.

The Access Gap Between Coverage and Actual Prescriptions

Despite the VA covering CGMs and the clinical evidence strongly supporting their use, the prescription rate is strikingly low. In a national study of nearly 370,000 VA patients on insulin therapy, only about 11% had been prescribed a CGM.³ That means almost nine out of ten insulin-treated veterans in the system were managing their diabetes without this technology, even though they were potentially eligible for it.

The reasons for that gap are not primarily about the veterans themselves. A national survey of VA primary care providers found that the vast majority recognized the clinical benefits of CGM, with nearly 80% agreeing that the devices help their patients. But only 8% felt they had adequate access to the resources needed to prescribe and support CGM use, and just 5% reported adequate support from facility leadership and other services. The strongest predictor of whether a provider would even discuss CGMs with patients was the provider’s own knowledge about how the devices work and how to interpret the data.⁴

This means that a veteran’s chances of being offered a CGM depend heavily on which VA facility they visit and which provider they see. At facilities where leadership actively supports diabetes technology programs and where staff have been trained on CGM, uptake is higher. At facilities where the infrastructure and training are lacking, a veteran with identical clinical needs may never hear about the option. The barrier is systemic, not clinical.

What to Do If Your Provider Has Not Mentioned CGMs

Given that the access gap is largely driven by provider-side factors, veterans often need to be their own advocates. If you are on insulin and your VA provider has not brought up continuous glucose monitoring, it is entirely reasonable to raise the topic yourself. You do not need to wait for a referral to endocrinology, though seeing a specialist can sometimes speed the process.

When you bring it up, a few things help. First, be specific about the problems you are having with current glucose management. If you experience frequent lows, if your blood sugar swings unpredictably, if you struggle to check your glucose as often as recommended, or if your last few lab results showed higher-than-target levels, say so. These are the clinical situations where CGMs make the strongest case. Second, ask whether the prescribing would go through the prosthetics service at your facility, and whether there is a diabetes technology coordinator or champion at your VA medical center. Some facilities have designated staff who handle CGM prescriptions and training, and connecting with that person can streamline the process considerably.

If your provider is unfamiliar with the ordering process or seems uncertain about eligibility criteria, you can also contact your facility’s prosthetics department directly. They can often clarify what documentation is needed and whether your situation qualifies. Veterans who have been told they do not qualify should ask specifically why, since eligibility has broadened in recent years and outdated assumptions sometimes persist.

Racial and Ethnic Disparities in CGM Prescriptions

The access gap is not evenly distributed. Research on VA CGM prescribing has revealed significant disparities along racial and ethnic lines. After accounting for clinical factors, health system characteristics, and patient demographics, Black or African American veterans had about 38% lower odds of receiving a CGM prescription compared to White veterans. Hispanic or Latino veterans had about 21% lower odds compared to non-Hispanic veterans. These disparities held up even when the analysis focused on subgroups with the clearest clinical reasons for CGM use.³

This pattern is not unique to the VA. Broader research on diabetes technology use among young adults with type 1 diabetes has found similar disparities across healthcare settings, with non-Hispanic Black individuals having the lowest rates of CGM use and non-Hispanic White individuals having the highest, and socioeconomic status alone does not fully explain the gap.⁵

What makes the VA findings particularly striking is that the VA system is designed to minimize many of the financial barriers that drive disparities elsewhere. Veterans receiving VA care do not face the copays, deductibles, or prior authorization hurdles that often block CGM access in private insurance or Medicare. When disparities this large persist even in a system that removes cost barriers, it points to factors like implicit bias in prescribing, uneven distribution of diabetes technology expertise across facilities, differences in how patients and providers communicate about treatment options, and structural factors that have not yet been fully identified. The VA has acknowledged this as a problem requiring intervention, but solutions are still in early stages.

How CGMs Compare to Traditional Fingerstick Monitoring

If you have been managing diabetes with fingerstick glucose checks, the shift to a CGM is a fundamentally different experience. A fingerstick tells you where your blood sugar is at a single moment. A CGM tells you where it is right now, where it has been over the past several hours, and which direction it is heading. That trend information is what changes behavior. You can see, in real time, how a meal, a walk, a stressful afternoon, or a missed medication dose affects your glucose, and you can respond before the situation becomes a medical problem.

Most current CGMs work by inserting a small, flexible sensor wire just under the skin, typically on the arm or abdomen, where it measures glucose in the fluid surrounding your cells. The sensor transmits readings to a receiver or smartphone app every few minutes, creating a continuous picture of your glucose levels. Sensors last anywhere from 10 to 14 days depending on the brand before needing replacement. You still may need occasional fingerstick checks for calibration or confirmation, depending on the device, but the days of pricking your finger four or more times daily can largely end.

For veterans who have been reluctant to check their blood sugar frequently because of the discomfort, inconvenience, or difficulty of fingersticks, particularly those with dexterity issues, vision problems, or neuropathy in the hands, a CGM removes a major obstacle. The device does the checking for you, automatically, around the clock.

Data Integration and What Your VA Care Team Sees

One of the advantages of using a CGM within the VA system is the growing ability to integrate device data with your electronic health record. The VA has been developing systems to pull CGM data directly into its health records platform, giving your care team access to long-term glucose patterns without requiring you to manually bring in reports or share device apps during appointments.⁶

This integration matters practically because it changes the nature of your clinic visits. Instead of discussing a single lab value drawn weeks ago, your provider can review weeks or months of continuous glucose data, identify patterns in when your blood sugar tends to spike or drop, and make more precise adjustments to your medications and insulin doses. For veterans who use VA telehealth services, this is especially valuable. A provider reviewing your CGM data remotely can make meaningful clinical decisions without requiring you to travel to a VA medical center, which is a significant benefit for the many veterans who live in rural areas far from the nearest facility.

Not all VA facilities have fully implemented this data integration yet, so your experience may vary. If your care team does not seem to have access to your CGM data, ask whether your facility supports it and what steps are needed to connect your device to their system. In the meantime, most CGM apps allow you to generate reports that you can print or share electronically before appointments.

What About Veterans Not on Insulin

The clearest path to a VA-covered CGM is for veterans already on insulin therapy, and the overwhelming majority of research in the VA population has focused on this group. But there is a growing conversation about whether CGMs should be available to veterans managing type 2 diabetes with oral medications alone, or even those with prediabetes who want to use glucose data to guide lifestyle changes.

The clinical case for CGMs in non-insulin-treated type 2 diabetes is still evolving, and the VA’s approach to coverage in this space reflects that uncertainty. Some providers may be willing to prescribe a CGM for a veteran on oral medications who is experiencing significant glucose variability or who has a strong clinical rationale, but this is not standard practice and will depend heavily on your individual provider and facility. If your diabetes management is stable on oral medications and your blood sugar levels are consistently near target, you are unlikely to receive a CGM through the VA at this point.

The consumer market has complicated this picture somewhat. Companies now sell CGMs directly to people without diabetes for general wellness monitoring, and some veterans may wonder why they cannot get a similar device through the VA if they are willing to use it. The short answer is that the VA allocates medical devices based on clinical need and established evidence, and the evidence base for CGM use outside of insulin-treated diabetes, while growing, has not yet reached the level that would justify broad coverage expansion.

Supplies and Ongoing Costs

One concern veterans sometimes have is whether, once they receive a CGM, they will face ongoing costs for sensors and transmitters. Within the VA system, supplies for an approved CGM are covered as part of your prosthetic benefit. You should not be paying out of pocket for replacement sensors or transmitters as long as you continue to meet the clinical criteria and reorder through VA prosthetics. Depending on your facility, reordering may happen through a phone call, through a secure messaging request, or through an automated reorder system.

Disruptions in supply can happen, though. Some veterans have reported delays in receiving replacement sensors, particularly during periods of high demand or supply chain issues. If you find yourself running low on sensors, contact your prosthetics department early rather than waiting until your last sensor is about to expire. Building in a small buffer helps avoid gaps in monitoring.

If you also have Medicare or private insurance in addition to VA healthcare, the question of which system to use for your CGM can get complicated. Generally, veterans find it simplest to keep all diabetes supplies within the VA system to avoid coordination problems, but if your situation involves dual coverage, it is worth asking your VA social worker or patient advocate about the best approach for your circumstances.

When CGMs May Not Be the Right Fit

CGMs are not a perfect solution for every veteran with diabetes. Some people have skin sensitivities or allergic reactions to the adhesive used to attach the sensor, which can cause irritation or rashes. Manufacturers have improved adhesive formulations over time, and workarounds like barrier wipes or alternative sensor placement sites help some people, but for a small number of users the skin issues are a dealbreaker.

There are also veterans who find the constant stream of glucose data more stressful than helpful. If seeing every fluctuation in your blood sugar causes anxiety or leads to overcorrecting with food or insulin, the device can do more psychological harm than clinical good. For these individuals, a periodic “diagnostic” use of CGM, wearing the sensor for a couple of weeks to identify patterns and then taking a break, may work better than continuous use. Providers sometimes prescribe CGMs in this intermittent fashion specifically because it delivers the insights without the burden of constant data.

Veterans with significant cognitive impairment may struggle to use the device or interpret its readings without caregiver support. If a caregiver is involved in your diabetes management and willing to engage with the device, CGM can still be beneficial. But the technology works best when someone is actively using the information it provides to guide daily decisions about food, activity, and medication.
