Does Medicare cover diabetic supplies?
Usually covered
Medicare Part B covers blood glucose monitors, test strips, and lancets as durable medical equipment, with quantity limits that differ for insulin users, plus continuous glucose monitors when specific criteria are met — insulin itself is billed through Part D except when used with a covered pump.
- Covered when You use insulin and need more frequent testing supplies — Medicare Part B allows higher monthly quantity limits for insulin users than for those who don't use it.
- Covered when You meet CGM coverage criteria (insulin use, or a documented history of problematic hypoglycemia) and your doctor completes the required visit and order.
- Not when You're looking for insulin coverage itself without a Part D or Medicare Advantage drug plan, and you're not using a Part B-covered insulin pump.

Part B treats most diabetes testing supplies as DME: blood glucose monitors, test strips, and lancets are covered when prescribed by your doctor. How many strips and lancets Medicare will pay for each month depends on whether you use insulin — insulin users are generally allowed more frequent testing supplies than those who don't.
Continuous glucose monitors (CGMs) are covered under Part B when specific criteria are met — most commonly, you use insulin, or you have a documented history of problematic hypoglycemia — and your doctor has an in-person or telehealth visit with you and orders the device and related supplies (like sensors).
Insulin itself is usually not a Part B item — it's typically covered through a Part D prescription drug plan or a Medicare Advantage plan with drug coverage. The exception is insulin used with a Medicare-covered external insulin pump, which is billed under Part B as durable medical equipment.
What people typically pay
After the Part B deductible, you generally pay 20% coinsurance on the Medicare-approved amount for monitors, test strips, lancets, and CGMs bought from a supplier that accepts assignment. A Medigap plan can reduce or eliminate the Part B coinsurance. For covered insulin, you pay no more than $35 for a one-month supply of each covered insulin product, with no deductible for the insulin.
Without coverage, costs vary widely. Paying cash, prices depend on the meter, brand of test strips, how often you test, and — for CGMs — the system and its sensors, which are typically the largest ongoing expense. Contact suppliers directly for current cash prices.
Actual amounts vary by supplier, brand, how often you test, and whether you carry Medigap or a Part D plan — treat any figures as ballpark rather than fixed prices.
How to actually get it covered
Get a doctor's prescription documenting your diabetes diagnosis and, for a CGM, the specific qualifying criteria — insulin use or a history of problematic hypoglycemia.
Get your monitor, strips, lancets, or CGM from a Medicare-enrolled supplier (pharmacy or DME supplier).
Confirm the supplier "accepts assignment."
Expect the Part B deductible, then 20% coinsurance, on the Medicare-approved amount for supplies — insulin itself is typically billed under Part D unless it's used with a Part B-covered pump.
Use the official supplier directory at medicare.gov/medical-equipment-suppliers to find an enrolled supplier.
Common questions
How many test strips and lancets will Medicare pay for each month?
Medicare sets monthly quantity limits based on whether you use insulin, and insulin users are generally allowed a higher number than non-insulin users. If your doctor documents that you need to test more often than the standard limit, additional supplies may be available when there's an explanation of medical necessity in your records. Ask your supplier what the current standard allowance is for your situation before you fill an order.
Does the same 20% coinsurance apply to a continuous glucose monitor and its sensors?
Yes. Once you meet the Part B deductible, you generally pay 20% of the Medicare-approved amount for the CGM and related supplies like sensors, the same cost sharing that applies to a standard monitor and strips (when your supplier accepts assignment). Because sensors are replaced regularly, that coinsurance repeats over time. A Medicare Supplement (Medigap) plan can cover part or all of the Part B coinsurance.
What happens if my diabetic supply claim is denied?
Denials often come down to missing documentation — no qualifying diagnosis on file, a supplier that isn't Medicare-enrolled, or a CGM order lacking the required evaluation by your provider. You have the right to appeal, and your Medicare Summary Notice explains how to request a redetermination. Fixing the underlying paperwork with your doctor and reordering through an enrolled supplier that accepts assignment can help avoid the problem in the first place.
Can I get my diabetic supplies at a regular pharmacy or do I need a DME supplier?
You can use either, as long as they're enrolled in Medicare and bill Part B for the supplies. Many pharmacies are Medicare-enrolled DME suppliers for glucose monitors, strips, and lancets, but not all are, so confirm before you buy. Using a supplier that accepts assignment protects you from being charged more than the Medicare-approved amount.
Since insulin isn't a Part B supply, how do I actually get it covered?
Insulin you inject with a pen or needle is covered through a Part D drug plan or a Medicare Advantage plan that includes drug coverage, not through Part B. The exception is insulin used with a Medicare-covered durable insulin pump, which is billed under Part B. If you only have Original Medicare with no drug plan and no covered pump, your self-administered injectable insulin won't be covered.
