What Medicare Covers for Diabetic Test Strips and Supplies

Medicare Part B covers diabetic test strips, but only if your doctor prescribes them and you meet specific requirements

Medicare Part B pays for blood glucose test strips, lancets, and lancing devices if you have diabetes and your doctor says you need them to manage your condition. The program covers these supplies under Durable Medical Equipment (DME), which means they are treated the same way as wheelchairs or oxygen tanks. You will pay 20 percent of the approved amount after you meet your Part B deductible; Medicare pays the remaining 80 percent.

The catch is that Medicare limits how many test strips you can receive each month based 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, the limit is usually lower — often around 30 to 50 strips per month, though this varies by your specific situation. Your doctor's prescription determines your limit, not your actual usage.

You must order your supplies through a Medicare-approved DME supplier, not from a pharmacy or online retailer. The supplier handles the paperwork with Medicare and ships the strips to your home. If you use a non-approved supplier, Medicare will not pay, and you will owe the full cost.

Key Takeaways

• Medicare Part B covers test strips, lancets, and lancing devices when prescribed by your doctor for diabetes management.
• You pay 20 percent of the approved cost after meeting your Part B deductible; Medicare covers the remaining 80 percent.
• Monthly limits depend on whether you use insulin and what your doctor prescribes, typically ranging from 30 to 100 strips per month.
• You must order through a Medicare-approved DME supplier; pharmacy purchases or non-approved suppliers are not covered.
• Your doctor must provide a written prescription that includes how often you should test each day.

How to order test strips through Medicare

Start by asking your doctor for a written prescription that states how many times per day you should test your blood glucose. The prescription needs to be specific — for example, "four times daily" rather than just "as needed." Your doctor will send this to a Medicare-approved DME supplier, or you can give the prescription to the supplier yourself.

To find an approved supplier, call Medicare at 1-800-MEDICARE (1-800-633-4227) and ask for suppliers in your area, or visit the Medicare website and use their DME supplier search tool. When you contact the supplier, give them your Medicare number and the prescription details. They will verify your coverage, confirm your monthly limit, and arrange delivery. Most suppliers ship supplies to your home every month automatically, though you can ask them to adjust the schedule if needed.

Keep your prescription on file with the supplier. If your testing needs change — for example, if you start or stop using insulin — ask your doctor for an updated prescription and notify your supplier. Using more strips than your limit allows means paying out of pocket for the overage.

What happens if your monthly limit is too low

If your doctor prescribed a limit that does not match how often you actually need to test, you have options. Talk to your doctor first and explain why you need more frequent testing. If your doctor agrees, they can write a new prescription with a higher limit and send it to your supplier. Medicare will honor the updated prescription going forward.

If your doctor will not increase the prescription, you can pay out of pocket for additional strips. Some people use a combination: they order their Medicare-covered strips from an approved supplier and buy extra strips from a pharmacy or online retailer when needed. This is legal, though it means paying the full retail price for the extra strips.

Another option is to look into whether you may have access to for a patient information program run by the test strip manufacturer. Many companies offer free or reduced-cost strips to people who cannot afford them, regardless of insurance status. Your doctor's office or the manufacturer's website can tell you whether you may have access to.

Medicare Advantage plans and test strips

If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your coverage for test strips may be different. Some Advantage plans cover test strips the same way Part B does; others have different limits, require prior approval from the plan, or charge a copay instead of 20 percent coinsurance. A few plans cover more strips per month than Original Medicare allows.

Call your Advantage plan's customer service number (on the back of your insurance card) and ask specifically about test strip coverage, monthly limits, and which DME suppliers are in-network. If your plan requires prior approval, the supplier can usually request it on your behalf — you do not have to do it yourself. If your plan's limit is lower than you need, the same options explore: talk to your doctor about a higher prescription, pay out of pocket for extras, or explore manufacturer information programs.

What test strips and supplies are covered

Medicare covers blood glucose test strips, lancets (the small needles you use to prick your finger), and lancing devices (the spring-loaded tools that hold the lancet). It does not cover glucose meters themselves — those are covered under a different program called the Durable Medical Equipment Prosthetics Orthotics and Supplies (DMEPOS) program, and you typically pay 20 percent after your deductible, just like strips.

Medicare does not cover continuous glucose monitors (CGMs) under the standard DME benefit, though some Medicare Advantage plans do cover them. If you use a CGM, contact your plan or call Medicare to ask whether your specific device is covered. Coverage for CGMs has been expanding, so it is worth asking even if you have been told no in the past.

Supplies like alcohol wipes, lancet containers, or glucose tablets are generally not covered by Medicare. You will need to purchase these yourself or check whether your DME supplier includes them as part of their service.

If you do not have Part B or are not yet on Medicare

If you have Original Medicare Part A only (hospital coverage) but not Part B (medical coverage), test strips are not covered. You would need to purchase them out of pocket or enroll in Part B during the next enrollment period. Part B has a monthly premium, and you pay this premium whether or not you use it.

If you are not yet on Medicare but will be soon, you can continue using your current insurance to cover test strips until Medicare starts. Once Medicare begins, your previous insurance will no longer pay for these supplies.

If you are under 65 and have Medicare because of a disability or end-stage renal disease, the same coverage rules explore: Part B covers test strips through an approved DME supplier, with the same monthly limits and 20 percent coinsurance.

Troubleshooting common problems

If Medicare denies your claim for test strips, the denial letter will explain why. Common reasons include: the supplier was not Medicare-approved, your prescription was missing or incomplete, you exceeded your monthly limit, or your doctor did not prescribe them. Read the letter carefully to see which reason applies. If the reason is a missing prescription, ask your doctor to send one. If the supplier was not approved, order from an approved supplier instead.

If you believe the denial was a mistake, you can file an appeal. The denial letter includes instructions on how to appeal and the important date (usually 120 days from the date of the letter). You can appeal on your own or ask your doctor or supplier to help. Many appeals are successful, especially if the problem was a paperwork error rather than a coverage rule.

If your supplier stops carrying your preferred brand of test strips, ask whether they carry a similar brand that Medicare covers. If not, you can request a different approved supplier. Medicare allows you to switch suppliers if your current one cannot meet your needs.

Frequently Asked Questions

Can I order test strips from my pharmacy instead of a DME supplier?

No. Medicare only pays for test strips ordered through a Medicare-approved DME supplier. If you order from a pharmacy, you will owe the full cost. However, you can use your pharmacy for other diabetes supplies like insulin or oral medications.

What if I use multiple types of test strips for different purposes?

Your monthly limit applies to all test strips combined, regardless of brand or type. If you need different strips for different situations, talk to your doctor about which one to prioritize or whether your prescription can be adjusted. Some people use one type for routine testing and buy a second type out of pocket for specific situations.

Do I have to use the same DME supplier every month?

No. You can switch suppliers at any time. If your current supplier is slow, out of stock, or unhelpful, call a different approved supplier and give them your prescription. The new supplier will take over your orders. You do not need Medicare's permission to switch.

Will Medicare cover test strips if I do not have a prescription from my doctor?

No. A doctor's written prescription is required. If your doctor has not prescribed test strips, ask them at your next visit. Explain how often you test and why you need the strips covered. If your doctor refuses to prescribe them, you can seek a second opinion from another doctor.

What happens to my test strip coverage if I switch from Original Medicare to a Medicare Advantage plan?

Coverage may change. Call your new Advantage plan before your coverage starts and ask about test strip limits, copays, and approved suppliers. If the new plan's coverage is worse, you may be able to switch back to Original Medicare during the annual enrollment period or if you have a may have access to life event.
