A prescription for a continuous glucose monitor can be the start of a coverage conversation—not the final answer. For Florida seniors with diabetes, the next questions are whether Medicare’s medical requirements are met, which supplier can bill the benefit and what the ongoing supplies will cost.
You do not necessarily have to take insulin to qualify. But having diabetes alone does not automatically qualify everyone for a continuous glucose monitor, often called a CGM. Knowing the difference can help you ask better questions before ordering a device or paying cash.
Can someone who does not use insulin qualify?
Yes, in some circumstances. Medicare’s coverage rules include people with diabetes who are treated with insulin and people with diabetes who have a qualifying history of problematic low blood sugar, or hypoglycemia.
The detailed criteria require documentation. For the non-insulin pathway, they describe either repeated glucose readings below 54 mg/dL that persist despite multiple attempts to adjust medication or the treatment plan, or a qualifying severe event involving altered functioning and help from another person.
Your treating practitioner must determine whether your history meets the requirements. A desire to learn more about food choices, a diabetes diagnosis or an occasional low reading should not be treated as an automatic coverage approval. Do not change your treatment to meet an insurance rule.
What must the doctor document?
The clinician must evaluate your diabetes control and eligibility. The rules also address training for you or your caregiver, use consistent with the device’s FDA indications, and a qualifying visit within six months before the order. Continued coverage requires follow-up visits every six months to document use of the CGM and the diabetes treatment plan.
Before an order is sent, ask the office: “Have the coverage criteria and required visit been documented, and which supplier will receive the records?” This is more useful than assuming that a prescription alone resolves every requirement.
Is a CGM covered by Part B or my drug plan?
Medicare lists qualifying continuous glucose monitors and their related supplies under Part B’s durable medical equipment benefit. That is a different billing route from many medicines covered through Part D.
This distinction matters at the counter. A pharmacy that fills your prescriptions may not be the right supplier for your particular equipment claim. Ask specifically whether it can process the CGM and supplies through your medical equipment coverage, rather than simply asking whether it “takes Medicare.”
Medicare’s official CGM coverage page provides the general framework. For your own order, have the supplier confirm the exact device, benefit and billing arrangements before delivery.
What could I pay for the device and sensors?
Under Original Medicare, after the Part B deductible, the usual share is 20% of the Medicare-approved amount when the supplier accepts assignment. Ask whether the supplier accepts assignment for the entire arrangement, including any rental months.
Do not translate that percentage into a dollar estimate using an advertised retail price. Ask for the Medicare-approved amount and your estimated responsibility. Also ask what the recurring supply allowance includes and how refills are handled.
If you have supplemental coverage, review how it works with the underlying claim. Our Medicare Supplement overview explains how Medigap fits alongside Original Medicare. Do not assume a supplement makes an otherwise noncovered device covered.
Need help sorting out the insurance questions? Schedule a complimentary, no-obligation My Local Coverage review or call (813) 608-0986. Bring your coverage cards, device name, supplier estimate and any coverage letter. We can help clarify which questions belong with the plan, supplier or treating office.
What if I have Medicare Advantage?
Start with your specific plan’s medical equipment arrangements. Ask which supplier you should use, whether authorization is needed, which device is covered and what your cost share will be. Get an answer for the exact plan and product instead of relying on another person’s experience.
Our Medicare Advantage coverage overview can help you understand the plan structure. A CGM question does not automatically mean you need to change plans. A review may confirm that your current coverage remains appropriate.
Frequently asked questions
Can I use only my smartphone?
Check before choosing a system. Medicare’s equipment policy distinguishes a durable receiver or qualifying insulin pump from a smartphone alone. Using a phone alongside a durable receiver can be permitted, but never using a qualifying receiver or pump can affect supply coverage. Ask the supplier to explain the device requirements for your arrangement.
Are backup test strips automatically billed separately?
No. Billing depends on the type of CGM. For a non-adjunctive CGM, the supply allowance includes necessary backup blood-glucose testing supplies; separate billing can be denied as unbundling. Have the supplier explain how the supplies your clinician recommends will be provided.
What should I do if the order is denied?
Keep the written notice and identify the stated reason. Ask whether the issue involves clinical documentation, the device, supplier billing or a plan requirement. Follow the notice’s instructions and deadlines for a review or appeal; do not assume that sending the same order again fixes the problem.
Check the whole order before paying
For families in Apollo Beach, Tampa Bay and across Florida, a useful coverage check connects the clinician’s order with the supplier’s billing and the expected ongoing cost. Keep the device name, order date, supplier contact and written estimate together.
Bring those details to a complimentary My Local Coverage review or call (813) 608-0986. There is no obligation to enroll or change coverage. Your clinician determines medical need; the insurer and applicable Medicare rules determine coverage.
