Continuous Glucose Monitors and Insulin Pump Guidelines
Continuous Glucose Monitors (CGMs) track glucose levels day and night through a small sensor applied to your skin. Medicare Part B covers therapeutic CGMs and their associated sensors and transmitters as Durable Medical Equipment.
Expanded Eligibility Rules for CGMs
Medicare has broadened CGM coverage, allowing many more beneficiaries to access this technology. You qualify if you have diabetes and are treated with any type or frequency of insulin.
Current guidelines eliminate older multiple-daily-injection rules. Using once-daily basal insulin qualifies you for full device coverage.
You also qualify without insulin if your doctor documents problematic hypoglycemia. This includes frequent severe low blood sugar or hypoglycemia unawareness.
Your prescribing clinician must document these low blood sugar events in your chart before ordering the device.
Ongoing Compliance and 2026 Supplier Rules
Qualifying for a CGM is only the first step in maintaining your Medicare benefit. To keep coverage active, you must see your prescribing clinician at least once every six months.
This regular follow-up visit can take place in person or through an approved telehealth consultation. Your clinician must evaluate your sensor data and confirm that using the device helps your diabetes management.
Important regulatory updates took effect on January 1, 2026, under the Centers for Medicare & Medicaid Services Home Health Final Rule.
This rule established new Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) accreditation standards and expanded competitive bidding. These updates impact which suppliers can provide CGMs and pumps.
Verify that your equipment vendor is an accredited, in-network Medicare contract supplier. Using an unaccredited supplier could leave you responsible for full costs.
Coverage Differences for Insulin Pumps
Medicare divides insulin pump coverage based on whether the device is reusable or disposable. Traditional durable insulin pumps that use external tubing are covered under Part B as durable medical equipment.
In contrast, tubeless disposable patch pumps fall under Medicare Part D prescription drug plans. Understanding this distinction ensures you file your claims through the correct Medicare benefit.
