Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for diabetic supplies in 2026 — and where a Medicare Advantage plan can fill the gap.
Quick answer: Yes — Part B covers diabetes testing supplies. Blood sugar (glucose) monitors, test strips, and lancets are covered as durable medical equipment. After the Part B deductible you pay 20% of the Medicare-approved amount, and you must use a Medicare-enrolled pharmacy or supplier.
Medicare Advantage (Part C) plans must cover at least everything Original Medicare covers, so diabetes supplies are included — but the copay, preferred pharmacies, and brand of meter can differ. Some plans also add extras. Check the plan's cost-sharing and pharmacy network before you fill your supplies.
Anyone on Medicare managing diabetes. The key practical steps are using a Medicare-enrolled supplier and confirming your meter/strips are covered by your plan, so you're only paying the 20% coinsurance rather than the full price.

See 2026 Medicare Costs →Yes. Part B covers blood sugar test strips, lancets, and glucose monitors as durable medical equipment. After the Part B deductible you pay 20% of the Medicare-approved amount, as long as you use a Medicare-enrolled supplier that accepts assignment.
Insulin used with a covered insulin pump is billed under Part B. Insulin you inject yourself is covered under a Part D drug plan, where a covered month's supply of each insulin is capped at $35 and has no deductible. Test strips and lancets are the Part B side of diabetes coverage.
