Medicare covers a new glucose meter once every 12 months, as long as you meet the basic requirements

Medicare Part B pays for one new glucose meter per year if you have diabetes and a doctor has ordered it as medically necessary. The meter itself is covered under durable medical equipment (DME), which means Medicare treats it like other devices you need to manage a chronic condition. You pay 20 percent of the approved amount after you meet your Part B deductible; Medicare pays the rest.

The 12-month window resets on a calendar year basis. If you received a meter in March, you can get another one covered starting January 1 of the following year. This is different from test strips, which Medicare covers in larger quantities throughout the year — the meter itself is the limited item.

The coverage applies whether you use insulin or manage your diabetes with oral medication or diet. Your doctor does not have to resubmit an order each year; once diabetes is documented in your medical record, you can work with a DME supplier to request a replacement when the 12 months have passed.

Key Takeaways

  • Medicare Part B covers one new glucose meter every 12 months if your doctor has documented that you have diabetes.
  • You pay 20 percent of the Medicare-approved amount after meeting your Part B deductible; the exact cost depends on which meter your supplier stocks.
  • The 12-month period runs on a calendar year, so coverage resets January 1 regardless of when you last received a meter.
  • Test strips are covered separately and in much larger quantities, so running out of strips does not affect your meter replacement schedule.
  • You must order through a Medicare-enrolled DME supplier, not directly from a manufacturer or pharmacy.

What counts as a covered glucose meter

Medicare covers a blood glucose monitor — the device you use to check your blood sugar by pricking your finger and placing a drop of blood on a test strip. The meter reads the strip and displays your blood sugar number. This is different from continuous glucose monitors (CGMs), which are covered under different rules and may have different frequency limits.

The meter must be ordered by your doctor and supplied through a Medicare-enrolled DME supplier. You cannot buy a meter over the counter and ask Medicare to reimburse you. The supplier submits the claim to Medicare, and Medicare pays them directly. You receive an invoice for your 20 percent share.

Medicare does not cover meters that are part of a bundle deal or sold as a starter kit with strips included. The meter and strips are billed separately, and only the meter counts toward your once-yearly limit.

How to order a replacement meter through Medicare

Start by contacting a Medicare-enrolled DME supplier in your area. You can find one by calling 1-800-MEDICARE or searching the Medicare supplier directory online. Tell them you have diabetes and your doctor has ordered a glucose meter. They will ask for your Medicare number and may contact your doctor's office to confirm the order.

The supplier will ask which meter brand you prefer or will recommend one they stock. Medicare approves several brands, including Accu-Chek, OneTouch, Contour, and others. The supplier handles the claim submission to Medicare. You should receive the meter within one to two weeks, along with an invoice showing your 20 percent cost-share.

Keep a record of the date you received the meter. When 12 months have passed, you can contact the same supplier or a different one to order your next replacement. There is no need to get a new doctor's order unless your doctor's previous order has expired or your diabetes diagnosis is no longer in your medical record.

What you pay out of pocket

Your cost is 20 percent of the Medicare-approved amount for the meter. The approved amount varies by meter brand and supplier, but typically ranges from $40 to $100 for the device itself. This means you might pay $8 to $20 out of pocket, depending on which meter the supplier provides.

You only pay this amount if you have already met your Part B deductible for the year. If you have not met the deductible, you pay the full approved amount until the deductible is satisfied, then 20 percent after that. Once you reach your out-of-pocket maximum for the year, Medicare covers 100 percent of the meter cost.

If you have a Medigap or Medicare Advantage plan, your supplemental coverage may pay some or all of your 20 percent share. Check your plan documents or call your plan to confirm what your meter will cost under your specific coverage.

What happens if your meter breaks or is lost

If your meter breaks or stops working before 12 months have passed, you may be able to get a replacement sooner, but this is not automatic. Contact your DME supplier and explain what happened. Some suppliers will replace a defective meter at no cost under the manufacturer's warranty, which does not count against your Medicare coverage limit.

If the meter was lost or damaged due to circumstances outside the manufacturer's control, Medicare may allow an exception to the 12-month rule. Your supplier can submit a request to Medicare explaining the situation. Medicare reviews these requests case by case, and approval is not may provide. Do not assume you will receive a free replacement — ask your supplier what documentation they need before you submit the request.

If you cannot get an exception and need a meter before your 12 months are up, you can purchase one out of pocket. Many meters cost $30 to $60 when bought directly from a pharmacy or online retailer.

Continuous glucose monitors have different coverage rules

If you use a continuous glucose monitor (CGM) instead of a traditional blood glucose meter, Medicare covers it under different rules. CGMs are covered for people with diabetes who use insulin, and the frequency of replacement depends on the specific device and your insulin regimen. Some CGMs are covered every 30 days, while others may have different intervals.

CGMs are not subject to the same 12-month limit as traditional meters. If you use both a CGM and a traditional meter, you can receive a new traditional meter once per year in addition to your CGM coverage. Talk to your doctor about which device is right for your situation, and ask your DME supplier to explain the coverage rules for whichever device you choose.

Frequently Asked Questions

Can I get a new meter before 12 months if I switch to a different brand?

No. Medicare's 12-month limit applies to the meter itself, not to a specific brand. Switching brands does not reset the clock. If you want a different brand before 12 months have passed, you would need to purchase it out of pocket.

Do test strips count toward the meter replacement limit?

No. Test strips are covered separately and have their own coverage rules. Medicare covers test strips in quantities based on how often your doctor says you need to check your blood sugar — typically 100 to 300 strips per month. The meter and strips are two separate items with two separate limits.

What if my doctor says I need a meter but I do not have a Medicare Part B deductible left?

You still pay 20 percent of the approved amount. The deductible only applies once per calendar year. Once you have met it, you pay 20 percent for all covered services for the rest of that year, including a glucose meter.

Can I order a meter directly from the manufacturer instead of a DME supplier?

No. Medicare only pays when you order through a Medicare-enrolled DME supplier. If you order directly from a manufacturer or pharmacy, Medicare will not cover the cost. Always confirm that your supplier is Medicare-enrolled before placing an order.

Does Medicare Advantage cover glucose meters differently?

Medicare Advantage plans must cover glucose meters at least as well as Original Medicare does, but some plans may cover them more often or with lower out-of-pocket costs. Check your plan's formulary or call your plan to find out your specific coverage and any prior authorization requirements.
