Medicare covers glucose test strips, but only under specific conditions and through particular suppliers

Medicare Part B covers glucose test strips and lancets for people with diabetes who use insulin or certain other medications. However, the coverage comes with rules: you need a prescription from your doctor, you must use a Medicare-approved supplier, and the number of strips covered per month depends on how often your doctor says you need to test.

If you use insulin, Medicare typically covers up to 100 strips per month. If you do not use insulin but take other diabetes medications, coverage is usually lower — often 25 to 50 strips per month, though your doctor can request more if medically necessary. The exact amount your doctor prescribes is what Medicare will cover.

The glucose meter itself is covered once every five years, and lancets are covered as part of your testing supplies. You pay 20 percent of the approved amount after you meet your Part B deductible, unless you have a Medigap or Medicare Advantage plan that covers more.

Key Takeaways

  • Medicare Part B covers glucose test strips and lancets for people with diabetes, but you must have a prescription and use a Medicare-approved supplier.
  • The number of strips covered per month depends on your medications — typically 100 strips if you use insulin, fewer if you do not.
  • You can find Medicare-approved suppliers by calling 1-800-MEDICARE or searching the Medicare Supplier Directory online.
  • You pay 20 percent of the approved cost after your Part B deductible, and some Medigap or Medicare Advantage plans cover the rest.

How to get your prescription and find an approved supplier

Start by talking to your doctor about how often you need to test your blood sugar. Your doctor will write a prescription that specifies the type of meter, the number of strips per month, and how often you should test. Bring this prescription with you when you contact a Medicare-approved supplier.

To find an approved supplier, call 1-800-MEDICARE and ask for suppliers in your area, or visit the Medicare Supplier Directory at dmepos.cms.gov (DMEPOS stands for Durable Medical Equipment, Prosthetics, Orthotics, and Supplies). When you call a supplier, have your Medicare number and your doctor's prescription ready. The supplier will verify your coverage, explain what you will pay, and arrange delivery or pickup.

Some suppliers offer automatic refills, so you do not have to reorder every month. Ask about this when you sign up — it can save you a phone call and make sure you never run out.

What happens if your doctor prescribes more strips than the standard amount

If you test more frequently than the standard coverage allows — for example, if you use an insulin pump or have unstable blood sugar — your doctor can request a higher amount. This is called a prior authorization or a request for exception. Your doctor's office usually handles this paperwork, not you.

Medicare will review the medical reason your doctor provides. If approved, you will be covered for the higher number of strips. This process typically takes one to two weeks. Ask your doctor's office to let you know the outcome so you can order the correct amount from your supplier.

Coverage differences between Original Medicare and Medicare Advantage

Original Medicare (Part A and Part B) covers glucose strips as described above, and you pay 20 percent of the approved cost. Medicare Advantage plans (Part C) must cover at least what Original Medicare covers, but many plans cover more — some cover 100 percent of strips with no copay, or a flat copay per month.

Check your Medicare Advantage plan's formulary or call the plan directly to see what your out-of-pocket cost will be. The formulary is the list of covered items and supplies. If your plan does not cover your preferred meter or strips, you can still use them, but you will pay the full cost yourself unless your doctor can show medical necessity for that specific brand.

What is not covered by Medicare

Medicare does not cover glucose test strips if you do not have diabetes or if you manage your diabetes through diet and exercise alone without medication. If you use only oral diabetes medications (pills), Medicare may still cover strips, but the amount is usually lower than for insulin users — ask your doctor and your supplier to confirm.

Continuous glucose monitors (CGMs) — devices that read your blood sugar automatically throughout the day — have different coverage rules and are not covered the same way as traditional test strips. If you use a CGM, contact Medicare or your plan directly to understand what is covered.

How to appeal if Medicare denies your claim

If Medicare denies coverage for your strips, you will receive a notice called an Explanation of Benefits (EOB). This notice explains why the claim was denied. Common reasons include: no prescription on file, the supplier was not Medicare-approved, or the amount requested exceeded what Medicare covers for your situation.

You have the right to appeal. Call the number on your EOB or contact 1-800-MEDICARE to ask about the next steps. If your doctor believes the denial is wrong, ask your doctor's office to submit additional medical information to support your case. Appeals can take several weeks, so order extra strips from a non-Medicare supplier in the meantime if you need them right away.

Tips for managing your costs

If you have a Medigap plan (supplemental insurance), check whether it covers the 20 percent you owe for strips — many do. If you have limited income, you may be may be able to access for Extra Help or Medicaid, which can reduce your out-of-pocket costs further. Call 1-800-MEDICARE to ask whether you may have access to.

Some manufacturers offer patient information programs that provide free or reduced-cost strips if you meet income requirements. Ask your doctor or supplier whether your meter brand has a program. Nonprofit organizations like the American Diabetes Association also maintain lists of resources for people who need help paying for supplies.

Frequently Asked Questions

Can I use any glucose meter, or does it have to be a specific brand?

You can use any meter, but Medicare only covers strips for meters on its approved list. When you order from a Medicare-approved supplier, they will help you choose a covered meter. If you already own a meter that is not on the list, you can still use it, but Medicare will not cover the strips.

What if I travel and need strips while I am away from home?

You can order strips from any Medicare-approved supplier, even if they are not in your home state. Some suppliers ship nationwide. If you are traveling internationally, Medicare does not cover strips purchased outside the United States, so plan ahead and bring enough from home.

Do I need a new prescription every time I reorder strips?

No. Your doctor writes one prescription that covers a set period — usually one year. The supplier will keep this prescription on file and refill your order each month without asking you to get a new one. If your testing needs change, ask your doctor for a new prescription.

What if my Medicare Advantage plan stops covering my preferred strips?

Plans can change their coverage each year. If your strips are no longer covered, ask your doctor whether a covered alternative will work for you. If not, your doctor can request a prior authorization to cover your preferred brand for medical reasons. You can also switch to a different Medicare Advantage plan during the annual enrollment period.

Are lancets covered separately, or do they come with the strips?

Lancets are covered separately under Medicare Part B. Your supplier will include them with your strip order, and you pay 20 percent of the approved cost for both together. You do not need a separate prescription for lancets — your doctor's prescription for strips covers them.
