Type 2 diabetes affects approximately 33% of Americans over 65 — and nearly half of that group doesn't have it adequately controlled. Poorly managed diabetes in seniors leads to cardiovascular disease, kidney failure, blindness, nerve damage, and limb amputations. The stakes could not be higher.
The good news: Medicare provides remarkably comprehensive coverage for diabetes care — including supplies, education, medications, and preventive testing — much of it at no cost to you. Most people with diabetes don't use all the benefits they're entitled to.
What Medicare Part B Covers for Diabetes
Blood Glucose Monitoring Supplies
Medicare Part B covers blood glucose monitors, test strips, lancets, and control solution for all insulin-treated Medicare beneficiaries. For those not using insulin, Part B covers limited testing supplies. You must use a Medicare-enrolled supplier and get a prescription from your doctor.
Insulin and Insulin Supplies
Insulin itself is covered under Part D (prescription drug coverage), not Part B — with one exception: insulin used in an insulin pump is covered under Part B as durable medical equipment. The insulin pump itself is also covered under Part B when prescribed for type 1 or insulin-dependent type 2 diabetes.
Continuous Glucose Monitors (CGMs)
Continuous Glucose Monitors like the Dexcom G7 and Abbott FreeStyle Libre are covered under Medicare Part B for insulin-treated diabetes. CGMs provide real-time glucose readings every few minutes and have been shown to dramatically improve glucose control and reduce dangerous hypoglycemic events in seniors. Coverage requires a prescription and use of a Medicare-enrolled supplier.
Diabetes Self-Management Training (DSMT)
This is one of the most valuable and underused Medicare diabetes benefits. Medicare covers up to 10 hours of initial diabetes education (individual or group) and 2 hours of follow-up education per year, at no cost to you. These programs teach blood sugar monitoring, meal planning, medication management, foot care, and sick-day management.
To access DSMT: ask your doctor for a referral to a Medicare-certified diabetes education program. Find one at diabetes.org/dces.
Medical Nutrition Therapy (MNT)
Medicare Part B covers Medical Nutrition Therapy sessions with a registered dietitian for people with diabetes or chronic kidney disease — free, with a referral from your doctor. Initial visit is 3 hours; follow-up visits are 2 hours per year.
Preventive Screening and Monitoring
- Hemoglobin A1C test: Covered under Part B when ordered by your doctor — measures average blood sugar over 3 months
- Diabetic retinopathy exam: Free once per year under Part B — critical because diabetes is the leading cause of blindness in adults
- Foot exam: Covered up to 4 times per year for people with diabetic peripheral neuropathy
- Kidney function tests: Covered for monitoring diabetic kidney disease
- Glaucoma screening: Free annually for diabetics — diabetes significantly increases glaucoma risk
Part D: Prescription Medications for Diabetes
All Medicare Part D plans must cover insulin and oral diabetes medications, though specific drugs, tiers, and copays vary by plan. Key insulin access rule starting in 2023: out-of-pocket costs for insulin are capped at $35 per month per covered insulin product under Part D — a dramatic reduction from previous years.
At your annual Part D enrollment review (October 15 – December 7), use Medicare's Plan Finder to compare plans based on your specific diabetes medications. Different plans can charge very different amounts for the same drugs.
Managing Diabetes After 65: Different Considerations
Diabetes management goals are sometimes different for seniors than for younger adults. Very tight blood sugar control (very low A1C targets) can be dangerous in seniors because of increased hypoglycemia risk — low blood sugar episodes can cause falls, cognitive impairment, and even cardiac events.
Current guidelines from the American Diabetes Association suggest more relaxed A1C targets (7.5–8.0% rather than 7.0%) for older adults with complex health situations. Discuss your personal target with your doctor — it should be individualized based on your life expectancy, other health conditions, and risk of hypoglycemia.
- Ask your doctor for a DSMT referral if you haven't had diabetes education
- Get your eyes examined annually — at no cost through Medicare Part B
- Get a foot exam if you have neuropathy — up to 4 times/year covered
- Ask about CGM coverage if you use insulin — it significantly improves control
- Review your Part D plan each October for the best coverage of your diabetes medications
- Check if you qualify for Extra Help to further reduce your medication costs
- Ask your doctor for a Medical Nutrition Therapy referral — it's free through Medicare
Frequently Asked Questions
Does Medicare cover diabetes supplies?
Yes — Medicare Part B covers blood glucose monitors, test strips, lancets, and control solution for all insulin-treated Medicare beneficiaries. Continuous glucose monitors (CGMs) like Dexcom G7 and FreeStyle Libre are also covered under Part B for insulin users. A prescription from your doctor is required.
How much does insulin cost with Medicare Part D in 2026?
Under Medicare Part D in 2026, out-of-pocket costs for insulin are capped at $35 per month per covered insulin product. This cap applies to all Part D plans regardless of formulary tier — a significant change that dramatically reduced insulin costs for seniors with diabetes.
Does Medicare cover diabetes education?
Yes — Medicare Part B covers up to 10 hours of initial diabetes self-management training (DSMT) and 2 hours of follow-up education per year at no cost. Medicare also covers Medical Nutrition Therapy (MNT) sessions with a registered dietitian for people with diabetes or chronic kidney disease.
What is the Medicare diabetes annual eye exam?
Medicare Part B covers one diabetic retinopathy eye exam per year for people with diabetes, at $0 after the Part B deductible. Diabetes is the leading cause of blindness in adults, making annual retinal exams critically important. Ask your doctor for a referral to an ophthalmologist for this exam.
What blood sugar level is too high for seniors?
Most diabetes guidelines recommend slightly relaxed blood sugar targets for older seniors — an A1C of 7.5–8.0% rather than the standard 7.0% target for younger adults. This is because very tight control increases hypoglycemia (low blood sugar) risk in seniors, which can cause falls and cardiac events.
