What Medicare Covers for the Bayer Microlet

Medicare Part B covers the Bayer Microlet lancing device — the small handheld tool that pricks your finger for blood glucose testing — but only if your doctor prescribes it and you meet specific conditions. The device itself is classified as durable medical equipment (DME), which Medicare will pay for after you meet your Part B deductible and pay your coinsurance share.

The coverage applies whether you use the Microlet for routine diabetes monitoring or for initial diagnosis. However, Medicare does not cover the lancets (the tiny needles) as a separate item under this classification. Lancets fall under a different category called "diabetic supplies," which has its own rules and coverage limits.

Your out-of-pocket cost depends on which DME supplier you use. Medicare pays 80 percent of the approved amount after your deductible; you pay 20 percent. If your supplier charges more than Medicare's approved amount, you may owe the difference — so comparing suppliers matters.

Key Takeaways

  • Medicare Part B covers the Bayer Microlet lancing device as durable medical equipment after you meet your deductible and pay coinsurance.
  • Your doctor must write a prescription for the device; Medicare will not cover it without one.
  • Lancets are covered separately under diabetic supplies, not as part of the device itself, and have their own monthly or yearly limits.
  • You pay 20 percent coinsurance after your Part B deductible; the exact amount depends on the DME supplier's Medicare-approved price.
  • Using a Medicare-approved DME supplier protects you from balance billing and ensures the lowest out-of-pocket cost.

How to Get Medicare to Cover Your Lancing Device

Start by asking your doctor — whether that is your primary care physician, endocrinologist, or diabetes educator — to write a prescription for the Bayer Microlet. The prescription must state that the device is medically necessary for your condition. Without this prescription, Medicare will deny the claim.

Once you have the prescription, contact a Medicare-approved DME supplier. You can find one by calling 1-800-MEDICARE or searching the Medicare Supplier Directory online at dmepos.cms.gov. When you call, give them your prescription and Medicare number. They will verify your coverage, tell you what you owe out of pocket, and arrange delivery.

The supplier will submit the claim to Medicare on your behalf. You should receive the device within one to two weeks in most cases. Keep your prescription and the supplier's paperwork for your records.

What You Pay Out of Pocket

Your cost depends on whether you have already met your Part B deductible for the year. For 2024, the Part B deductible is $240 (this amount changes yearly). Once you meet it, you pay 20 percent of the Medicare-approved amount for the device.

The Medicare-approved amount for a Bayer Microlet is typically between $30 and $50, though this varies by region and supplier. If the approved amount is $40, you would pay $8 after your deductible. If you have not met your deductible yet, you pay the full approved amount until you reach $240, then switch to the 20 percent coinsurance.

Some DME suppliers charge more than Medicare's approved amount. If they do, you may owe the difference on top of your coinsurance — this is called balance billing. Using a Medicare-approved supplier that accepts assignment (meaning they agree to charge only the Medicare-approved amount) protects you from this extra cost.

Lancets and Other Diabetic Supplies

While Medicare covers the Bayer Microlet device itself, lancets are covered under the diabetic supplies benefit, which is separate. Medicare Part B covers lancets, test strips, and glucose monitors as diabetic supplies, but with limits: you can receive supplies for up to 100 finger sticks per month, or about three test strips and three lancets per day.

To get lancets covered, you need a prescription from your doctor stating how often you test. You order them through a Medicare-approved DME supplier or a pharmacy. Like the lancing device, you pay 20 percent coinsurance after your Part B deductible.

If you test more frequently than the 100-per-month limit — for example, if you use an insulin pump or have type 1 diabetes — you can request an exception. Your doctor must document the medical reason for higher frequency, and you submit the request to Medicare. Approval is not automatic, but Medicare does grant exceptions when the clinical need is clear.

If You Have a Medigap or Medicare Advantage Plan

If you have a Medigap (supplemental insurance) plan, it may cover some or all of your 20 percent coinsurance for the lancing device. Check your plan documents or call your Medigap insurer to confirm what they cover for DME.

If you have a Medicare Advantage plan (Part C), coverage for the Bayer Microlet works differently. Your plan must cover all the same items that Original Medicare covers, but your out-of-pocket costs, deductibles, and coinsurance may be different. Contact your Medicare Advantage plan directly to learn what you pay for a lancing device and whether you need a specific supplier.

Common Reasons Medicare Denies Coverage

Medicare denies coverage for a Bayer Microlet most often because there is no prescription on file. Even if your doctor discussed the device with you, Medicare needs the written prescription submitted with the claim. If you receive a denial, ask your doctor's office to send the prescription to your DME supplier right away.

A second common reason is using a supplier who is not Medicare-approved. If you order directly from a retailer or online seller that does not participate in Medicare, the claim will be denied. Always verify that your supplier is on the Medicare Supplier Directory before placing an order.

Occasionally, Medicare denies coverage if it determines the device is not medically necessary — for example, if your doctor's notes do not document a diabetes diagnosis or a reason for frequent blood glucose monitoring. If this happens, ask your doctor to provide additional documentation and resubmit the claim.

Frequently Asked Questions

Do I need a new prescription every time I order lancets?

No. Your doctor writes one prescription for lancets that specifies the frequency (for example, "three times daily"). That prescription remains valid and covers multiple orders over time, unless your doctor changes it. You do not need a new prescription for each refill.

Can I use the Bayer Microlet with any brand of lancets?

The Bayer Microlet is designed to work with Bayer lancets, though some third-party lancets may fit. Medicare covers lancets only if they are prescribed and ordered through a Medicare-approved supplier. Using non-standard lancets may void the device warranty and could affect coverage.

What happens if I lose or damage my lancing device?

Medicare will cover a replacement device if your doctor writes a new prescription and you have a documented reason for the replacement (loss, damage, or malfunction). You will pay the same coinsurance as you did for the original device. Keep your receipt and documentation of what happened.

Does Medicare cover continuous glucose monitors instead of finger-stick testing?

Yes, Medicare Part B covers continuous glucose monitors (CGMs) for people with diabetes who use insulin, though coverage rules and out-of-pocket costs differ from the lancing device. If you are interested in a CGM as an alternative to finger-stick testing, discuss it with your doctor — they can determine whether you meet the criteria and submit the necessary documentation to Medicare.

Can I buy the Bayer Microlet without insurance and then bill Medicare?

No. Medicare will not reimburse you for a device you purchased on your own. You must obtain the device through a Medicare-approved DME supplier with a valid prescription before purchase. This ensures the claim is processed correctly and you pay only your required coinsurance.
