Does Medicare Cover a Continuous Glucose Monitor?

Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for a continuous glucose monitor (CGM) in 2026 — and where a Medicare Advantage plan can fill the gap.

Quick answer: Yes, if you qualify. Part B covers a continuous glucose monitor as durable medical equipment when your doctor orders one and you take insulin or have a history of problem low blood sugar (hypoglycemia). After the Part B deductible you pay 20% of the Medicare-approved amount for the monitor and sensors.

Part B covers a continuous glucose monitor (CGM) and related supplies as durable medical equipment (DME) when your doctor or other provider orders one and you meet Medicare's rules: you take insulin, or you have a documented history of problems with low blood sugar (hypoglycemia). Before ordering, your provider must evaluate you and confirm you're eligible, and you (or your caregiver) must have had enough training to use the device as directed. You also have to keep routine in-person or Medicare-approved telehealth visits with your doctor to stay covered. After you meet the Part B deductible you pay 20% of the Medicare-approved amount, and Medicare pays its share. There may be limits on how much or how often you get sensors and supplies, and you must use a supplier enrolled in Medicare — one that accepts assignment keeps your cost to the deductible and 20% coinsurance.

Medicare Advantage: what some plans add

Medicare Advantage (Part C) plans cover CGMs and sensors too, but through their own DME suppliers and cost-sharing, often with prior authorization. Use an in-network supplier and confirm the copay and any quantity limit before you order.

Who this matters to

Anyone on Medicare managing diabetes with insulin, or with a history of dangerous low-blood-sugar episodes. The things to get right: a doctor's order, meeting the insulin-or-hypoglycemia rule, device training, and using a Medicare-enrolled supplier that accepts assignment.

Frequently asked questions

Does Medicare cover Dexcom or FreeStyle Libre?

Medicare covers therapeutic CGMs as durable medical equipment when you meet the requirements — a doctor's order plus using insulin or having a history of problem low blood sugar. Coverage is by category, not brand; ask a Medicare-enrolled DME supplier which models they carry and what you'll pay.

Do I have to use insulin to get a CGM through Medicare?

Not necessarily. Medicare may cover a CGM if you take insulin, or if you have a documented history of problems with low blood sugar (hypoglycemia). Your provider has to evaluate you and confirm you meet the rule before ordering.
