Yes, Medicare covers diabetic test strips and supplies, and after your yearly deductible you pay 20% of the cost. Part B pays for the monitor, the strips, the lancets, and the control solution as durable medical equipment. So the box you picked up for your dad that made you wince at the counter? Most of it is covered, and here's exactly how the benefit works.

What Diabetic Test Strips and Supplies Does Medicare Cover?

The everyday supplies you use to check a blood sugar level are covered by Medicare Part B, and they're covered as durable medical equipment (DME), which is the same benefit category as a walker or a hospital bed. For someone with diabetes, Part B covers the blood sugar monitor itself, the blood sugar test strips, the lancets and the lancet device you use to draw the drop of blood, and the glucose control solutions that check whether your meter is reading accurately.

That's the core testing kit, and it's worth saying plainly: none of it is Part D drug coverage. These are Part B supplies, ordered by your doctor and billed the way any other piece of medical equipment is. If you've been assuming your test strips run through your drug plan, that's the first thing to sort out, because it changes both who pays and where you pick them up.

What Will You Actually Pay?

Here's how the money works. Medicare Part B doesn't pay 100%. After you've met your annual Part B deductible, you generally pay 20% of the Medicare-approved amount for your diabetes supplies, and Medicare pays the other 80%. The deductible for 2026 is $283, so that's what you pay out of pocket for covered Part B services before the 20% coinsurance kicks in.

The "Medicare-approved amount" matters here. It's not the sticker price a pharmacy might quote you off the shelf. It's the rate Medicare has set for that item, and your coinsurance is a share of that number, not of whatever a cash customer would be charged.

If you carry extra coverage, your share can shrink. A Medigap policy is designed to pick up costs like the Part B deductible and coinsurance, and if you're on a Medicare Advantage plan instead of Original Medicare, your plan sets its own copays for diabetes supplies. The coinsurance math above is the Original Medicare baseline. Check your own plan's rules if you have one of these, because that's where your real number comes from.

How Many Diabetic Test Strips and Supplies Will Medicare Cover?

This is the part that surprises people at the pharmacy counter, so it's worth knowing before you're standing there. Medicare has a routine quantity it covers for test strips and lancets, and that amount turns on one thing: whether you're being treated with insulin.

  • If you are not treated with insulin, Medicare covers up to 100 test strips and 100 lancets every three months.
  • If you are treated with insulin, Medicare covers up to 300 test strips and 300 lancets every three months.

Roughly speaking, that's about one test a day for someone not on insulin, and about three a day for someone who is. Those are the usual amounts, not a hard ceiling: if your doctor wants you testing more often, Medicare covers the larger quantity when the additional documentation criteria are met, and denies the excess when they aren't. So that's a conversation to have with your doctor about documenting why, before the order goes in.

Where Do You Buy Them? Check the Supplier First

This one quietly trips up more people than the cost does. Medicare's own instruction is to make sure both your doctors and your DME suppliers are enrolled in Medicare, and to ask a supplier whether they participate in Medicare before you get any equipment. Plenty of pharmacies and mail-order companies will happily sell you strips without that ever coming up, so it falls to you to ask.

It's worth asking, because it shows up in your bill: if a DME supplier doesn't participate in Medicare or won't accept assignment, you may be charged more. Accepting assignment means they agree to the Medicare-approved amount as full payment, which keeps your share to the standard coinsurance and no more. It's a two-minute call before you set up a refill that can save you a surprise bill three months from now.

What About Insulin, Pumps, and Diabetic Shoes?

Diabetes care runs well beyond the testing kit, and those other pieces follow different Medicare rules. How your injected insulin is covered, whether an insulin pump falls under Part B, and how therapeutic shoes for diabetic foot problems are handled are all separate questions with their own coverage paths and costs. They're not part of the test-strip-and-lancet DME benefit this guide covers.

Rather than guess at those here, we've mapped them out in a dedicated guide. If you're trying to get a full picture of what Medicare pays for across all of diabetes care, start with our Medicare diabetes coverage guide, which walks through the Part B and Part D pieces side by side.

Frequently Asked Questions

Does Medicare cover a blood sugar monitor?

Yes. A blood sugar (glucose) monitor is covered by Medicare Part B as durable medical equipment for people with diabetes, right alongside the test strips, lancets, and control solution. You'll pay the Part B deductible and then 20% of the Medicare-approved amount, and Medicare tells you to make sure the supplier you use is enrolled in Medicare.

Do I have to use insulin for Medicare to cover test strips?

No. Insulin isn't a requirement, Medicare covers test strips either way. What it changes is the routine quantity: people treated with insulin get a higher routine allowance than those who aren't, as the quantity section above breaks down.

Are diabetic supplies covered under Part B or Part D?

Your testing supplies, the monitor, test strips, lancets, and glucose control solutions, are Part B (durable medical equipment), not Part D. That's why they don't run through your drug plan the way a prescription would. Injected insulin and some other diabetes items are handled differently, which our diabetes coverage guide breaks down.

Why won't my pharmacy bill Medicare for my strips?

Most likely because that pharmacy isn't enrolled with Medicare as a DME supplier. Medicare's own advice is to make sure both your doctors and your DME suppliers are enrolled, and to ask a supplier whether they participate in Medicare before you get equipment, so ask directly before you fill the order.
