Medicare covers a wide range of diabetes supplies and medications, but what you pay and how you access them depends on which part of Medicare applies. Part B handles most testing equipment and insulin pumps, while Part D covers most insulin and oral diabetes drugs. Understanding which part covers what helps you avoid overpaying and plan your out-of-pocket costs for 2026.
This guide breaks down exactly what Medicare covers for diabetes, how much it costs, and what programs can reduce your expenses further.
What Medicare Covers for Diabetes
Medicare splits diabetes coverage across two main parts: Part B (medical insurance) and Part D (prescription drug coverage). A few preventive services also fall under Part B at no cost to you.
Medicare Part B: Supplies and Equipment
Part B covers diabetes supplies that your doctor prescribes as medically necessary. After you meet the annual Part B deductible ($257 in 2026), Medicare pays 80% of the approved amount and you pay the remaining 20%.
Part B covers:
- Blood glucose monitors (glucometers)
- Test strips and lancets for self-monitoring
- Insulin pumps (non-disposable, external pumps)
- Insulin used in an insulin pump (capped at $35 per month under the Inflation Reduction Act)
- Continuous glucose monitors (CGMs) that meet Medicare criteria
- Therapeutic shoes for people with diabetic foot problems (one pair per year)
One important 2026 change: Starting January 1, 2026, most CGMs moved from Part B to pharmacy/Part D coverage for the majority of Medicare beneficiaries. If you use a CGM, verify with your plan whether your specific device is now billed under Part D rather than Part B, since the cost-sharing structure will differ.
Medicare Part D: Insulin and Oral Medications
Part D covers most injectable insulin, inhaled insulin, and the supplies needed to use them, including syringes, needles, alcohol swabs, and gauze. Part D also covers oral diabetes medications such as metformin and newer drugs like semaglutide (Ozempic, Wegovy) when prescribed for diabetes management, though formulary coverage varies by plan.
Key 2026 rules under Part D:
- Insulin is capped at $35 per month per insulin product, with no deductible applied to insulin
- The out-of-pocket maximum under Part D is $2,000 in 2026 (reduced from prior years under the Inflation Reduction Act)
- The cap applies to all covered insulins regardless of which tier your plan places them on
Preventive Services at No Cost
Medicare Part B covers several diabetes-related preventive services at no charge when you see a provider who accepts Medicare assignment:
- Diabetes screenings (up to 2 per year if you're at risk)
- Diabetes self-management training (DSMT) up to 10 hours in the first year, 2 hours per year after
- Medical nutrition therapy for people diagnosed with diabetes
- Annual wellness visits where your doctor can review your diabetes management
2026 Medicare Cost Summary for Diabetes
| Service or Supply | Medicare Part | Your Cost (2026) |
|---|
| Blood glucose meter | Part B (DME) | 20% after $257 deductible |
| Test strips and lancets | Part B (DME) | 20% after $257 deductible |
| Insulin pump | Part B (DME) | 20% after $257 deductible |
| Insulin used in pump | Part B | Capped at $35/month |
| Injectable insulin (pen, vial) | Part D | Capped at $35/month per insulin |
| Oral diabetes medications | Part D | Varies by plan formulary/tier |
| CGM devices (most) | Part D (as of 2026) | Varies by plan |
| Diabetes screenings | Part B preventive | $0 |
| Diabetes self-management training | Part B | $0 (with referral) |
| Medical nutrition therapy | Part B | $0 |
The $35 Insulin Cap Explained
The Inflation Reduction Act capped Medicare insulin costs at $35 per month for each covered insulin product. This applies to both Part B (insulin used in an insulin pump) and Part D (injectable or inhaled insulin). There is no deductible for covered insulins, meaning the cap applies from day one of your plan year.
If you take multiple types of insulin (for example, a long-acting basal insulin and a fast-acting mealtime insulin), the $35 cap applies separately to each product. Your total monthly insulin cost could be $35, $70, or more depending on how many distinct insulin products you use.
Starting in 2026, some specific insulin products like Fiasp and Novolog may have slightly adjusted cap amounts based on CMS pricing negotiations. Check your plan's 2026 formulary for the exact figures.
Continuous Glucose Monitor (CGM) Coverage in 2026
CGMs have become a standard tool for diabetes management, and Medicare coverage expanded significantly in recent years. As of 2026, most CGMs fall under Part D pharmacy coverage rather than Part B DME coverage for the majority of beneficiaries.
To qualify for CGM coverage under Medicare, you generally must:
- Have a diagnosis of diabetes
- Be treated with insulin or have a history of problematic hypoglycemia
- Receive a prescription from your treating physician
Popular CGM brands covered include Dexcom G7, Abbott FreeStyle Libre 3, and Medtronic devices. Because coverage shifted to Part D for most people in 2026, your specific out-of-pocket cost depends on your plan's formulary and whether the device is on a preferred tier.
If you relied on Part B DME coverage for your CGM in prior years, contact your plan to confirm how your device is now billed so you are not caught off guard by a different cost-sharing structure.
How Medicare Advantage (Part C) Handles Diabetes
If you are enrolled in a Medicare Advantage (MA) plan rather than Original Medicare, your diabetes coverage works differently. MA plans must cover at least everything Original Medicare covers, but they set their own cost-sharing rules within CMS-approved limits.
Many Medicare Advantage plans include additional diabetes benefits such as:
- Lower copays on testing supplies
- Extra allowances for over-the-counter supplies
- Telehealth visits with diabetes educators
- Preferred pharmacy networks with lower insulin costs
If you have a Medicare Advantage plan, review your Summary of Benefits or call your plan directly to understand your diabetes-specific benefits.
Medicare Savings Programs: Reducing Your Diabetes Costs Further
If your income is limited, Medicare Savings Programs (MSPs) can dramatically cut what you pay for diabetes care. MSPs are state-administered programs that help pay Medicare premiums, deductibles, and cost-sharing.
2026 Medicare Savings Program Income Limits
| Program | Who Qualifies | Monthly Income Limit (Single) | Monthly Income Limit (Couple) | What It Covers |
|---|
| QMB (Qualified Medicare Beneficiary) | Income up to 100% FPL | $1,350 | $1,824 | Part A and B premiums, deductibles, copays |
| SLMB (Specified Low-Income Medicare Beneficiary) | Income 100-120% FPL | $1,616 | $2,184 | Part B premium only |
| QI (Qualifying Individual) | Income 120-135% FPL | $1,816 | $2,455 | Part B premium only |
Resource limits for 2026 are approximately $9,950 for a single person and $14,910 for a married couple (some states have higher limits or no resource limits at all).
For someone with diabetes, QMB is the most valuable program. QMB eliminates your Part B deductible and coinsurance, which means your testing supplies, glucometer, and insulin pump costs drop to $0 out of pocket. Providers cannot bill QMB members for Medicare cost-sharing.
You apply for Medicare Savings Programs through your state Medicaid agency, not through Medicare directly.
Extra Help / Low Income Subsidy (LIS)
Extra Help is a federal program that reduces Part D drug costs. People with Extra Help pay reduced or $0 premiums, have no coverage gap, and pay very low copays for covered drugs. In 2026, people with full Extra Help typically pay $0 to $11.20 for brand-name drugs and $0 to $4.50 for generics, which significantly reduces out-of-pocket insulin and oral medication costs beyond the standard $35 cap.
To qualify, your income must be below approximately 150% of the Federal Poverty Level. You can apply through Social Security at ssa.gov.
Step-by-Step: Getting Your Diabetes Supplies Covered
Step 1: Confirm your Medicare coverage type.
Check whether you have Original Medicare (Parts A and B plus a standalone Part D plan) or a Medicare Advantage plan. This determines where you get supplies and how much you pay.
Step 2: Get a prescription from your doctor.
Medicare requires a prescription for blood glucose monitors, test strips, insulin, and CGMs. Your doctor must document that the supplies are medically necessary. For DSMT and nutrition therapy, you need a referral.
Step 3: Use a Medicare-enrolled supplier for testing equipment.
For supplies covered under Part B (meters, test strips, lancets), you must use a DMEPOS (Durable Medical Equipment, Prosthetics, Orthotics, and Supplies) supplier enrolled in Medicare. You can find one at medicare.gov/care-compare.
Step 4: Use a preferred pharmacy for insulin and drugs.
For Part D covered insulin and oral diabetes medications, use a pharmacy in your plan's network. Preferred pharmacies typically have lower copays. Many plans now allow 90-day mail-order supplies at a reduced cost.
Step 5: Apply for Medicare Savings Programs or Extra Help if your income qualifies.
Contact your state Medicaid agency or visit benefits.gov to apply. Many people who qualify do not realize it. There is no downside to applying.
Step 6: Review your coverage annually during Open Enrollment.
Medicare drug formularies change each year. During Open Enrollment (October 15 to December 7), review whether your plan still covers your insulin and medications at an acceptable cost, and switch plans if needed.
What Medicare Does NOT Cover for Diabetes
Medicare does not cover everything related to diabetes management. Items generally not covered include:
- Over-the-counter test strips and supplies purchased without a prescription
- Diabetic foods or special meal plans
- Most gym memberships or weight loss programs (unless a Medicare Advantage plan includes them)
- Insulin that is not on your Part D plan's formulary (though you can request an exception)
- Cosmetic procedures related to diabetes complications
If your medication is not on your plan's formulary, your doctor can request a formulary exception, which may allow coverage at a higher tier copay.
Frequently Asked Questions
Does Medicare cover insulin in 2026?
Yes. Medicare Part D covers most injectable and inhaled insulins with a $35 per month cap per insulin product. Insulin used in an insulin pump is covered under Part B, also with a $35 monthly cap. There is no deductible for covered insulins.
Does Medicare cover continuous glucose monitors (CGMs)?
Yes, but coverage shifted in 2026. Starting January 1, 2026, most CGMs are covered under Part D pharmacy benefits rather than Part B DME for most beneficiaries. You still need a prescription and a diabetes diagnosis. Check your specific plan for CGM formulary details and cost-sharing.
Does Medicare cover Ozempic or Wegovy for diabetes?
Medicare Part D may cover semaglutide (Ozempic) when prescribed for type 2 diabetes management, depending on your plan's formulary. Wegovy (higher-dose semaglutide for weight loss) has limited Part D coverage. Coverage expanded recently for cardiovascular risk reduction indications. Check your plan's current formulary to confirm.
How much do diabetes test strips cost with Medicare?
After meeting the Part B deductible ($257 in 2026), Medicare pays 80% of the approved amount for test strips purchased from a Medicare-enrolled supplier. You pay the remaining 20%. If you have a Medicare Supplement (Medigap) policy, it may cover that 20%. QMB members pay nothing.
Can I get free diabetes supplies through Medicare?
QMB members typically pay $0 for supplies covered under Part B, since QMB eliminates deductibles and coinsurance. Preventive services like diabetes screenings and self-management training are also free under Part B. Extra Help significantly reduces drug costs under Part D.
What is the Medicare Part B deductible for 2026?
The Part B deductible is $257 in 2026. Once you meet it, Medicare pays 80% of covered services and you pay 20%.
Does Medicare cover diabetes education?
Yes. Medicare covers up to 10 hours of Diabetes Self-Management Training (DSMT) in the first year and 2 hours per year after that. Medical nutrition therapy is also covered. Both require a referral and must be delivered by an accredited program.
How do I apply for Medicare Savings Programs?
Apply through your state Medicaid agency. You can find your state's application process at medicare.gov or benefits.gov. Eligibility is based on income and resources, not your health conditions. Many people who qualify have not applied.
