The Big Question: Part B vs. Part D
The most common source of confusion is knowing which part of Medicare pays for which item. Medicare doesn’t lump all “diabetic supplies” into one bucket. Instead, they split them based on whether the item is considered “Durable Medical Equipment” (DME) or a medication.
Medicare Part B: The “Equipment” Coverage
Medicare Part B is your medical insurance. It covers outpatient care and, crucially for you, Durable Medical Equipment (DME).
If you have Original Medicare and your doctor prescribes these items for use in your home, Part B typically covers 80% of the Medicare-approved amount (after you meet your deductible). You (or your supplemental insurance) pay the remaining 20%.
Items Covered Under Part B:
Medicare Part D is strictly for prescription drugs. This is usually an add-on plan you purchase separately or part of a Medicare Advantage plan.
Items Covered Under Part D:
Important 2025 Update: Thanks to the Inflation Reduction Act, the cost of a month’s supply of each covered insulin product is capped at $35, and you do not have to pay a deductible for it. This applies to both Part D and Part B (pump) insulin.
Medicare doesn’t give you an unlimited supply of test strips; they have strict “utilization guidelines” based on whether or not you use insulin.
Because you need to check your sugar more frequently to dose your insulin, Medicare allows for more supplies.
If you manage diabetes with pills (like Metformin) or diet alone, Medicare covers fewer supplies.
“Can I Get More If I Need Them?”
Yes. If your doctor deems it medically necessary for you to test more often—for example, if your blood sugar fluctuates wildly or you are pregnant—they can write a prescription explaining why. You will need to keep a testing log for six months to prove you are actually using the extra supplies.
Many New York residents believe they must use a national mail-order company to get their diabetic supplies covered by Medicare. This is not true.
While Medicare has a “National Mail-Order Program” that requires you to use specific suppliers if you want goods shipped to your door, you always have the option to buy locally.
You can walk into a Medicare-enrolled supplier—like a local pharmacy or a medical supply store in Floral Park—and pick up your supplies in person. For many seniors, this is a better option because:

Continuous Glucose Monitors (like the Dexcom or FreeStyle Libre) have revolutionized diabetes care. In the past, Medicare coverage for these was very strict. However, guidelines have expanded.
As of 2025, Medicare Part B covers CGMs if:
Pro-Tip for NY Residents: If you are on a Medicare Advantage plan (Part C), coverage might vary slightly, but most plans follow the standard Medicare guidelines. Always check your specific plan’s “Summary of Benefits.”
Navigating insurance in New York can be tricky. Follow this checklist to ensure your supplies are covered:
1. Get a Specific Prescription: A generic note saying “Diabetic Supplies” isn’t enough. Your doctor must write a prescription that includes:
2. Check Your Supplier: Ensure you are buying from a Medicare-enrolled supplier. If you buy from a supplier who isn’t enrolled, Medicare will not pay a cent, and you will be stuck with the full bill.
3. Ask About “Assignment”: You want a supplier who “accepts assignment.” This means they agree to the Medicare-approved price. If they don’t, they can charge you “Excess Charges” (up to 15% more).
4. Keep Your Testing Logs: If you are requesting extra supplies above the standard limits, keep a written log of your blood sugar readings. Medicare audits these frequently.

Q: Does Medicare cover diabetic socks?
A: Generally, no. Medicare does not cover diabetic socks for the general diabetic population. However, if you have a venous stasis ulcer or other specific wounds, they might be covered as “wound dressings,” but this is rare. Medicare does cover diabetic shoes and inserts once per year if you have qualified foot conditions.
Q: I have both Medicare and Medicaid (Dual Eligible). Do I pay anything?
A: In New York, if you have both Medicare and Medicaid (full coverage), Medicaid usually covers the 20% coinsurance that Medicare leaves behind. This means your cost for diabetic supplies could be $0. Be sure to show both cards to your supplier.
Q: Can I switch from mail-order back to a local store?
A: Yes! You are not locked into a mail-order contract forever. You can choose to pick up your next prescription at a local participating supplier whenever you choose.
