A Practical, Step-by-Step Guide to CGM Insurance Coverage:
Continuous glucose monitors (CGMs) like Dexcom and Libre systems are now routinely covered by Medicare and many commercial health insurance plans when specific clinical criteria are met.
According to the official Medicare coverage policy, CGMs and related supplies may be covered under Medicare Part B if you have diabetes, are treated with insulin, or have a documented history of problematic hypoglycemia, and your provider prescribes a CGM.
This guide explains how to navigate the CGM coverage with the health insurance process, including what documentation is required, how to work with your provider and insurer, and the steps that improve your chance of approval. It also explains how Medically Modern can help with insurance verification, benefits checks, and home delivery.

What Does “Dexcom and Libre Covered” Mean?
Dexcom and Libre covered by insurance means that health plans, including Medicare, Medicare Advantage, Medicaid, and many commercial plans, will pay for continuous glucose monitor devices and supplies when coverage rules are met.
A CGM is a wearable device that tracks glucose levels throughout the day, helping people with diabetes manage their condition more effectively. These devices typically include sensors worn on the body and a receiver or smartphone app for glucose data.
Who Typically Qualifies for CGM Coverage?
Insurers generally require:
- A diagnosis of diabetes.
- A prescription from a qualified healthcare provider for a continuous glucose monitor.
- Evidence that the device is medically necessary. Most commonly, insulin therapy or a history of problematic hypoglycemia.
- Documentation that you (or a caregiver) have sufficient training to use the device as prescribed.
Medicare covers CGMs when the provider confirms that you take insulin or have a documented history of significant low glucose events.
Most commercial plans (including employer-sponsored insurance) also cover popular CGMs such as Dexcom G6/G7 and FreeStyle Libre systems when similar clinical documentation is provided.

Step-by-Step: How to Get Dexcom and Libre Covered by Insurance
Getting CGM coverage involves coordination between you, your healthcare provider, and your insurer. Follow these steps to improve your chance of approval:
1. Talk to Your Healthcare Provider (Clinician)
- Request a prescription for the CGM device you need (Dexcom or Libre).
- Ask your clinician to document your diabetes diagnosis, insulin therapy status, and any history of hypoglycemia in a clinical note.
- Make sure your clinician includes detailed medical necessity information.
- Ensure you have had a visit with your provider within the past 6 months as part of the eligibility criteria for many insurers, including Medicare.
2. Choose a Supplier That Handles Insurance
Working with a supplier like Medically Modern makes the insurance process easier because they:
- Verify your insurance benefits and what portion of the Dexcom and Libre system will be covered.
- Submit the necessary documentation and prior authorization (if required) to your insurer.
- Coordinate shipping once coverage is approved.
This support can reduce delays and administrative burden, helping you get the device sooner.

3. Submit Prior Authorization (If Required)
Some plans require prior authorization before they approve CGM coverage. Prior authorization means your insurer reviews the clinical documentation before deciding to pay for the device.
You may need to provide:
- A prescription and clinical note that support the need for CGM.
- Evidence that you use insulin or have significant hypoglycemia.
- Records showing that previous glucose monitoring (e.g., fingerstick tests) is insufficient.
Ensure your clinician knows your insurance’s prior authorization requirements.
4. Wait for Approval or Request an Appeal
- Once prior authorization is submitted, the insurer reviews the documentation.
- If the plan approves, CGM supplies (sensors, transmitters, and receivers) will be covered according to your benefits.
- If coverage is denied, you can work with your provider and supplier to submit an appeal, providing additional clinical records and justification.
Medically Modern helps patients through the appeal process when needed.
Common Insurance Coverage Scenarios
Insurance coverage for CGMs varies based on the plan type:
Medicare
Medicare Part B covers therapeutic CGMs for eligible people with diabetes if specific clinical criteria are met. You may need to meet all of the following:
- Diagnosis of diabetes.
- Prescription from a qualified provider.
- Insulin treatment or documented problematic hypoglycemia.
- Training and evaluation by a healthcare provider.
After you meet the Part B deductible, you typically pay 20% of the Medicare-approved amount if your supplier accepts assignment.
Commercial and Employer-Sponsored Plans
Most commercial plans cover major CGM brands (including Dexcom and FreeStyle Libre) for people with diabetes when clinical criteria and prior authorization requirements are satisfied. Many plans now have extensive pharmacy or durable medical equipment (DME) benefits.
Medicaid and Other Government Plans
Some state-run Medicaid programs and plans like TRICARE also cover CGM systems when FDA-approved and medically necessary.
What If You Don’t Have Diabetes?
Coverage for a continuous glucose monitor insurance policy usually requires a diabetes diagnosis. Some Medicare policies may approve CGMs for people without insulin treatment if they have a documented history of problematic hypoglycemia and meet other criteria, but this situation is uncommon and depends on the insurer and clinical documentation.
