Managing diabetes on Medicare can feel confusing, but you don’t have to figure it out alone. Medicare covers many diabetes supplies and services through Part B and Part D, though what it pays for and your costs depend on the part, your plan, and doctor’s orders.
This post walks you through what Medicare typically covers—meters, test strips, lancets, insulin delivery devices, and prescription meds—and how costs, limits, and recent changes may affect your care. If you want one-on-one help, The Modern Medicare Agency has licensed agents who will review your needs, compare plan options, and help you get coverage that fits your budget without extra fees.
Understanding Medicare Diabetic Supplies Coverage
Medicare can pay for many diabetes supplies, tests, and education you need. You’ll learn which supplies are covered, what rules you must meet, and how Parts A, B, C, and D handle coverage and costs.
What Diabetic Supplies Does Medicare Cover
Medicare Part B covers many supplies used for blood glucose monitoring when your doctor orders them. Covered items often include blood glucose meters, test strips, lancet devices, and blood glucose control solutions.
Medicare also covers insulin pumps and related supplies when medically necessary and ordered by your doctor. Part B may also cover diabetes self-management training and diabetes-related medical nutritional therapy.
Insulin that does not require an injection device may be covered under Part B if it’s used with an insulin pump. Supplies for administering insulin by syringe or pen are generally covered under Part D when you get insulin through a pharmacy.
If you use continuous glucose monitors (CGMs) or other newer devices, coverage depends on medical necessity and current Medicare rules. Your doctor must document the need and meet specific criteria for some devices.
Eligibility Requirements
You must have Original Medicare (Part A or Part B) to get Part B coverage for diabetes supplies. A physician or qualified practitioner must prescribe the supplies and document medical necessity.
For insulin pumps and certain durable medical equipment (DME), Medicare requires specific diagnoses and clinical records that show prior treatment and ongoing need. Part D coverage for insulin and related pharmacy supplies requires enrollment in a Part D plan or Medicare Advantage plan that includes drug coverage.
You may face limits on quantities or frequency for test strips and supplies. Always keep copies of prescriptions, doctor notes, and receipts to prove eligibility if Medicare requests documentation.
How Coverage Works Under Different Parts of Medicare
Part B covers DME and medically necessary diabetes supplies when ordered by a doctor. You generally pay 20% of the Medicare-approved amount after meeting the Part B deductible.
Medicare pays the rest if the supplier accepts assignment. Part D covers most outpatient prescription insulins and some supplies like syringes and pens.
Costs depend on your Part D plan’s formularies, tiers, and deductible. Medicare Advantage (Part C) plans must cover at least what Original Medicare covers but can offer lower copays or additional benefits.
Medigap plans can help pay Part B coinsurance for covered supplies, but they do not cover Part D drugs.
Medicare Part B and Diabetic Supplies
Medicare Part B helps pay for many diabetes tools you use daily. It covers certain monitoring devices, supplies for checking blood sugar, and some insulin delivery items when they meet Medicare rules.
Blood Glucose Monitors
Part B covers blood glucose monitors when your doctor orders them for diabetes care. You typically qualify if you have Medicare Part B and a signed order or prescription from your treating physician.
Medicare will pay 80% of the Medicare-approved price after you meet the Part B deductible; you pay the remaining 20% unless a secondary plan helps. Monitors must come from approved suppliers who follow Medicare rules.
Coverage can include standard meters and, in some cases, newer technologies like continuous glucose monitors (CGMs) if your doctor shows medical necessity. Ask your provider for the written order and check that the supplier accepts Medicare assignment.
Test Strips and Lancets
Medicare Part B covers blood glucose test strips and lancets as durable medical equipment when a doctor prescribes them. Coverage limits can apply: Medicare may allow a specific number of strips per day based on your treatment plan.
Your supplier must be Medicare-enrolled and provide the supplies according to the doctor’s order. You usually pay 20% coinsurance after the Part B deductible.
If you use a non-participating supplier or get more than the allowed quantity, you could face extra charges. Keep copies of prescriptions and supplier receipts to avoid billing issues.
Insulin and Insulin Delivery Devices
Part B covers insulin only when used with an insulin pump that Medicare approves as durable medical equipment. Insulin for use with a pump and the pump itself can be covered if a doctor documents that you need a pump for glucose control.
Pumps must meet Medicare criteria and come from enrolled suppliers. If you inject insulin with syringes or pens, Medicare Part D drug plans usually cover that insulin and supplies, not Part B.
However, Part B does cover certain related supplies like infusion sets and pump supplies if the pump is covered. Expect to pay 20% for Part B-covered items after the deductible, while Part D coverage follows that plan’s rules.
Medicare Part D and Prescription Diabetic Medications
Medicare Part D covers many diabetes drugs, including most insulins you inject and common oral medications. Your plan’s list of covered drugs, rules on fills, and cost tiers determine what you pay and how easily you can get each medicine.
Covered Insulins
Part D plans generally cover insulins that you inject or inhale and the supplies needed to administer them when those supplies are tied to a covered drug. That includes vials, pens, and some pump supplies if the insulin itself is on your plan’s formulary.
Coverage and cost depend on the tier the insulin is placed in; lower tiers usually mean lower copays. You often need a prescription and may face limits on quantity or refill timing.
Prior authorization can apply, meaning your plan must approve the insulin before it pays.
Oral Diabetes Medications
Part D covers most oral diabetes drugs used to lower blood sugar. Each plan lists covered pills and places them into tiers that affect your cost.
Some newer oral drugs may sit in higher tiers and carry higher copays or coinsurance. Plans can require step therapy, where you try a preferred drug first, or prior authorization for certain medicines.
You should check a plan’s formulary before you enroll.
Formulary and Restrictions
A plan’s formulary is the official list of covered drugs. Formularies vary widely between Part D plans and Medicare Advantage plans with drug coverage.
Key restrictions include prior authorization, step therapy, quantity limits, and tier placement—all affecting access and cost. You must check if your exact medication, dose, and supply limits are listed.
If a drug isn’t covered, you can ask for an exception or switch plans during enrollment windows.
Costs and Out-of-Pocket Expenses
You will face set deductibles, coinsurance percentages, and supplier rules that shape what you pay for diabetes supplies. Knowing these specifics helps you plan for monthly costs and avoid surprise bills.
Deductibles and Coinsurance
Medicare Part B usually applies an annual deductible before it pays for covered diabetic supplies. After you meet that deductible, Part B typically pays 80% of the Medicare-approved amount for items like insulin pumps and certain testing supplies.
You are generally responsible for the remaining 20% coinsurance. For Part D (prescription drugs), insulin and some related supplies follow the plan’s drug cost stages: deductible (if your plan has one), your plan’s copay/coinsurance, a coverage gap for some people, and then catastrophic coverage.
In 2025, a $2,000 annual out-of-pocket cap on Part D drugs limits what you pay for prescriptions, which can lower costs for insulin users. Keep receipts and track payments toward deductibles and caps to avoid surprises.
Impact of Medigap Plans
Medigap (Medicare Supplement) plans do not add new diabetes benefits, but they reduce your out-of-pocket costs for items Medicare covers. A Medigap plan can pay the 20% coinsurance that Part B leaves you with, and may cover Part A/B deductibles depending on the plan you choose.
Medigap does not work with Medicare Advantage; it pairs with Original Medicare. If you use Original Medicare and want lower cost-sharing for diabetic supplies, a Medigap plan can be helpful.
Compare premiums against expected savings—higher monthly premiums may be worth it if you use many covered supplies.
Preferred Suppliers and Impact on Costs
Medicare may require you to buy certain diabetes supplies from enrolled or “preferred” suppliers to get full coverage. If a supplier bills Medicare directly and participates in Medicare, you usually avoid extra out-of-pocket charges.
Using non-participating suppliers can lead to higher bills or paperwork. For Medicare Part B equipment billed as Durable Medical Equipment (DME), confirm the supplier is enrolled in Medicare and accepts assignment.
For Part D prescriptions, using in-network pharmacies and mail-order options often lowers copays.
How to Obtain Diabetic Supplies Through Medicare
You will learn how to find suppliers who bill Medicare, what paperwork you need, and how ordering and delivery typically work. Follow each step to avoid denied claims and extra costs.
Finding Approved Suppliers
Start by choosing suppliers that accept Medicare assignment. This means they bill Medicare directly and follow Medicare’s rules.
Ask the supplier if they are a Medicare-enrolled supplier and if they accept assignment before you buy. Use the Medicare Supplier Directory online or call 1-800-MEDICARE to confirm a supplier’s enrollment and any supplier number.
If you have a Medicare Advantage plan, check with your plan first; some plans require in-network suppliers.
Required Documentation
You need a written doctor’s order or prescription that shows your diabetes diagnosis, the supplies you need (like test strips, lancets, or a glucose monitor), and how often you will use them. The order should include the supply quantity and medical reason.
Keep proof of medical necessity, such as a recent office visit note or diabetes treatment plan. If Medicare asks, you must show these records to get coverage.
Ordering and Delivery Process
Place orders through a Medicare-enrolled supplier or an in-network supplier for your plan. Confirm the supplier will bill Medicare or your Medicare Advantage plan directly.
Ask about shipping fees and return policies before finalizing your order. Expect Medicare Part B to cover certain supplies at 80% after your Part B deductible, unless you have a Medicare Advantage plan that changes cost-sharing.
Track deliveries and keep receipts and the supplier’s invoice in case of billing issues.
Additional Coverage Considerations
Medicare can help pay for many diabetes supplies, but you must meet rules, get proper prescriptions, and choose in-network suppliers. You may also find extra help from state programs, face coverage limits, or need to appeal denials.
State Assistance Programs
States and local programs can lower your out-of-pocket costs for insulin, test strips, and pumps. Programs include Medicaid for dual-eligibles, state pharmacy assistance programs (SPAPs), and diabetes-specific grants.
Eligibility rules vary by state and can depend on income, age, and whether you have full Medicaid or a Medicare Savings Program. Check your state’s SPAP for enrollment steps and covered items.
If you qualify for Medicaid, many diabetic supplies may cost less or nothing.
Coverage Limitations
Medicare Part B and Part D cover many diabetes items, but rules limit quantity, frequency, and specific products. You need a doctor’s prescription stating medical necessity.
Part B often covers durable medical equipment like insulin pumps and certain supplies, while Part D covers insulin and some injectable supplies. You may still owe deductibles, copays, or coinsurance.
Medicare can require use of enrolled suppliers and may restrict brand or type of supplies based on formularies or coverage rules. Keep written prescriptions and supplier documentation to avoid denials.
Appeals and Denials
If Medicare denies coverage, act quickly. Start with a redetermination request to the plan or Medicare contractor within the stated deadline on the denial notice—usually 60 days.
Include your doctor’s medical records and a clear statement why the supply is medically necessary. If redetermination fails, you can escalate to a reconsideration, a hearing, and then a Medicare Appeals Council review.
Document every phone call and keep copies of forms. Your doctor should write a supporting letter that cites medical need and prior treatments.
The Modern Medicare Agency’s licensed agents guide you through each appeals step, help assemble paperwork, and represent your case when needed, all without added fees.
Recent Updates Affecting Medicare Diabetic Supplies
Medicare has changed rules that affect coverage for continuous glucose monitors (CGMs) and insulin pumps. These updates may expand who qualifies and how supplies are billed, so you should check your plan details now.
Starting in 2026, CMS updated home health rules that can change CGM and pump access for some beneficiaries. Coverage may depend on medical records and ordering rules, which can affect how quickly you get new devices or supplies.
Part B still covers many supplies, but limits and supplier rules can change. You may face quantity limits or need a DME supplier who follows strict Medicare guidelines.
Ask about prior authorization and documentation to avoid delays. If you use a Medicare Advantage plan, your benefits may differ from Original Medicare.
Plans often follow CMS rules but can add extra perks or different costs. Review your plan each year during open enrollment to align coverage with your needs.

Frequently Asked Questions
This section explains what Medicare covers for diabetic supplies, how to get them, and what forms and costs to expect. It also tells you when The Modern Medicare Agency can help you find the best plan and a Medicare-approved supplier.
Which diabetic supplies are covered under Medicare Part B?
Medicare Part B covers blood glucose monitors, test strips, lancets, and glucose control solutions when your doctor orders them as medically necessary. It also covers therapeutic shoes or inserts for people with severe diabetic foot disease and some diabetes self-management training.
After you meet the annual Part B deductible, Medicare typically pays 80% of the approved amount and you pay 20% coinsurance unless you have supplemental coverage. You must use suppliers that accept Medicare assignment for full benefit billing.
The Modern Medicare Agency helps you find Part B–friendly suppliers and plans that lower your out-of-pocket costs.
Are insulin pumps and related supplies covered by Medicare for individuals under 65 years of age?
Medicare coverage rules do not change with age for people who qualify for Medicare early due to disability. Insulin pumps and related supplies may be covered if a doctor documents that they are medically necessary and you meet Medicare’s criteria.
Coverage often requires proof that other insulin delivery methods failed to control your blood sugar. You may face deductible and coinsurance costs unless a secondary policy covers them.
The Modern Medicare Agency can connect you to agents who review your medical needs and find plans that reduce charges for pumps and supplies.
What is the procedure to get diabetic supplies through a mail-order supplier approved by Medicare?
Get a written order or prescription from your doctor that specifies the supplies, quantity, and medical necessity. Choose a supplier that accepts Medicare and enrolls in Medicare billing; confirm they will file claims directly to Medicare.
You may need a signed Certificate of Medical Necessity (CMN) for certain items. Place your order, provide your Medicare ID, and verify delivery schedules and replacement supplies.
The Modern Medicare Agency can recommend Medicare-approved mail-order suppliers and guide you through enrollment.
Can seniors obtain free diabetic supplies, and if so, how?
Medicare itself does not usually provide supplies entirely for free. Some Medicare Advantage plans or supplemental programs may cover supplies with low or no copay for members.
Community health programs, state assistance, or charitable clinics sometimes offer free or low-cost supplies to those who qualify. Contact The Modern Medicare Agency to compare plans with low-cost supply options and learn about local assistance programs that might reduce your expenses.
Are diabetic testing strips and lancets eligible for coverage under Medicare Part D?
Testing strips and lancets are primarily covered under Medicare Part B when they are durable medical equipment tied to a glucose monitor. Part D coverage may apply for certain diabetes-related supplies or drugs, like non-insulin diabetes medications, but not typically for standard blood glucose test strips tied to home monitors.
Always check plan formularies and confirm coverage before buying. The Modern Medicare Agency’s agents review plan details so you avoid buying supplies that won’t be covered.
What is required on a Medicare Certificate of Medical Necessity (CMN) form for diabetic supplies?
A CMN must include patient identification and a clear description of the item or supply. The treating physician’s signature and documentation of medical necessity are required.
The form often asks for diagnosis, duration of need, and justification for why the item is required for home use. Some supplies require periodic updates or additional notes from the doctor.
