If you've ever put off asking about a CGM or insulin pump because you weren't sure whether insurance would cover it, you're not alone. The connection between diabetes technology and insurance coverage can feel murky, and it's easy to assume the answer is "probably not covered" before you've even checked. The reality is that coverage for CGMs and insulin pumps has expanded significantly in recent years, and many people who qualify aren't taking advantage of benefits they've already paid into. This guide walks through what's typically covered, what you'll need to qualify, and how to make the process as straightforward as possible.
What Diabetes Supplies Are Typically Covered by Insurance?
Coverage varies by plan, but the following categories of diabetes supplies are commonly included under Medicare, Medicaid, and most private insurance plans with appropriate documentation:
- Continuous glucose monitors (CGMs): Including sensors, transmitters, and receivers for systems like Dexcom and Abbott FreeStyle Libre
- Insulin pumps: Including the pump itself and ongoing supplies such as infusion sets, reservoirs, and cartridges
- Insulin pods: Tubeless delivery systems may qualify under DME coverage depending on your plan and device
- CGM-integrated pump systems: Closed-loop systems that pair a CGM with an automated insulin delivery pump
Most of these supplies are classified as Durable Medical Equipment (DME) under Medicare and many private plans, which determines how they're billed and what documentation is required. A valid prescription from a healthcare provider is the starting point for nearly all of them.
Understanding Medicare Coverage for CGMs and Insulin Pumps
Medicare coverage for diabetes technology has improved considerably in recent years. In April 2023, the Centers for Medicare and Medicaid Services (CMS) expanded CGM eligibility in a way that made coverage more accessible for more people. According to the American Diabetes Association, Medicare now covers CGMs for beneficiaries who meet any of the following criteria:
- You use insulin (any type, any amount) to treat your diabetes
- You have a documented history of problematic hypoglycemia, which includes more than one Level 2 hypoglycemic event (glucose below 54 mg/dL) that persisted despite medication adjustments, or a single Level 3 event requiring third-party assistance
In addition to meeting one of those clinical criteria, Medicare also requires that you have had an in-person or Medicare-approved telehealth visit with your healthcare provider within six months of ordering the CGM, and that your provider has confirmed you've received appropriate device training (your prescription itself serves as documentation of this).
Under Original Medicare Part B, CGMs and related supplies are covered as DME. After meeting the Part B deductible ($283 in 2026), Medicare typically covers 80% of the approved cost, leaving a 20% coinsurance for the patient. Many Medicare Advantage plans cover these supplies at a lower or even $0 copay, depending on the plan. For those with both Medicare and Medicaid (dual eligibility), Medicaid may cover the remaining coinsurance and deductible costs.
Insulin pump coverage through Medicare follows a similar structure but has its own eligibility documentation requirements. Coverage is also evaluated separately from CGM coverage, even for integrated systems that use both. If you're exploring a device like the Medtronic MiniMed 780G or the Tandem t:slim X2 with Control-IQ, your provider and supplier will typically handle prior authorization for pump and CGM coverage separately.
One important note for Medicare beneficiaries: coverage for Dexcom CGM products requires the use of a standalone receiver (not just a smartphone) to qualify under Part B. Make sure to confirm with your supplier that your setup meets Medicare's DME requirements before ordering.
Private Insurance, Medicaid, and How to Get the Process Started
Most private insurance plans, including employer-sponsored plans and Affordable Care Act marketplace plans, cover CGMs and insulin pumps for eligible patients. Requirements generally include a diabetes diagnosis, insulin use or documented clinical need, and a valid prescription. Some plans also require prior authorization, which means your provider submits documentation to your insurer confirming the medical necessity of the device before it's approved.
Medicaid coverage varies by state. Many states include CGMs and insulin pumps as covered benefits for Medicaid enrollees with diabetes, but eligibility criteria and the specific devices covered differ. If you're on a state Medicaid plan and aren't sure what's available to you, your healthcare provider or a DME supplier like Adapt Health Diabetes can help verify your benefits.
Here's a general overview of what the coverage process looks like, regardless of plan type:
- Step 1: Talk to your provider. Your healthcare provider will assess your clinical needs and write a prescription for the appropriate device. This is also where prior authorization documentation begins if your plan requires it.
- Step 2: Verify your benefits. A DME supplier (like Adapt Health Diabetes) contacts your insurer to confirm your coverage, eligibility, and any cost-sharing responsibilities before your order ships.
- Step 3: Review your out-of-pocket costs. Depending on your plan, you may owe a deductible, coinsurance, or copay. Your supplier will walk you through what to expect before you commit.
- Step 4: Receive your supplies. Once coverage is confirmed, your device and supplies are typically shipped directly to your home on an ongoing schedule.
For supplies like the Dexcom G7 sensor or the FreeStyle Libre 3 Plus sensor, most of the documentation and communication with your insurer happens between your provider and your supplier. Your main job is to have that initial conversation with your care team.
Why It's Worth Taking the Time to Check Your Coverage
Diabetes technology has proven benefits for glucose control, hypoglycemia prevention, and quality of life, but those benefits are only accessible if you can afford the tools. With coverage expanded under Medicare and widely available through private plans, many people who assumed CGMs or insulin pumps were out of reach are discovering they're already covered. Checking your benefits costs nothing, and it can open the door to better management with far less financial stress. At Adapt Health Diabetes, verifying coverage on your behalf is part of what we do.

Frequently Asked Questions About Insurance Coverage for Diabetes Supplies
Do I need a prescription to get a CGM or insulin pump covered by insurance?
Yes. A valid prescription from a licensed healthcare provider is required for insurance coverage of CGMs and insulin pumps under Medicare, Medicaid, and most private plans. The prescription also serves as documentation that you've received appropriate device training, which Medicare specifically requires. If you don't currently have a prescription, the first step is a conversation with your provider about whether a CGM or pump is appropriate for your management needs.
What if my insurance requires prior authorization?
Prior authorization means your insurer wants clinical documentation confirming the device is medically necessary before approving coverage. This is common for insulin pumps and, depending on your plan and diagnosis, may also apply to CGMs. Your provider's office typically handles this process, often in coordination with your DME supplier. It can add time to the approval process, so it's helpful to start early and confirm with your supplier what documentation will be needed.
Does Medicare cover CGMs for people who don't use insulin?
Since the 2023 coverage update, Medicare can cover a CGM for a person with diabetes who does not use insulin if they have a documented history of problematic hypoglycemia. This includes at least two Level 2 hypoglycemic events (glucose below 54 mg/dL) that persisted despite medication adjustments, or a single Level 3 event that required someone else's help for treatment. Your provider will need to document this history as part of the coverage process.
Will I have any out-of-pocket costs even with insurance coverage?
It depends on your plan. Under Original Medicare Part B, patients typically pay 20% coinsurance after meeting the annual Part B deductible. Many Medicare Advantage plans reduce this further, and some cover CGM supplies at $0 copay. For private insurance, your out-of-pocket responsibility will depend on your deductible, copay structure, and whether the device is on your plan's formulary. Adapt Health Diabetes will walk you through your specific cost-sharing before your order ships so there are no surprises.
What if my insurance doesn't cover the specific CGM or pump I want?
Insurance plans typically have a list of covered devices, and your options may be narrowed by what's on that list. If a device you're interested in isn't covered, your provider can sometimes submit a letter of medical necessity to request an exception, particularly if a covered alternative wouldn't meet your clinical needs. Our team can help you understand what's available under your plan and identify the best covered options for your situation.
