Dexcom CGM Insurance Coverage: What You Need to Know

Navigating insurance coverage for medical devices like Dexcom Continuous Glucose Monitoring (CGM) systems can be complex and overwhelming.

Understanding your insurance options and how to maximize coverage is crucial for accessing the life-changing benefits of CGM technology.

In this guide, we'll explore everything you need to know about Dexcom CGM insurance coverage, from understanding different insurance plans to tips for navigating the insurance process effectively.


Understanding Dexcom CGM Insurance Plans 

  • Private Insurance:
    Most private health insurance plans cover Dexcom CGM systems to some extent, but it's like a treasure hunt - you have to find the details!

    Coverage varies depending on your specific plan and provider. Your first step would be review your insurance policy documents or contact your insurance company to understand the loot: deductibles (money you pay upfront), copayments (fixed amount you pay per use), and any special requirements (like pre-approvals).

  • Medicare & Medicaid:

    Good news! Dexcom CGM is covered by Medicare for eligible beneficiaries who meet certain criteria. This coverage includes both the Dexcom G6 and G7 systems.

    Medicare coverage typically requires a prescription from your healthcare provider and may involve specific documentation and paperwork.

    Here are some documents and paperwork required by Medicare:

  • Certificate of Medical Necessity (CMN):
    Your doctor fills out this form to explain why you require a Dexcom CGM and how it will enhance your diabetes management. 
    Think of it as a convincing argument for why you deserve this treasure!

  • Medicare Assignment of Benefits Form:
    By signing this form, you authorize Medicare to receive your bills directly from your doctor. It streamlines the process for everyone involved in securing your Dexcom CGM.

  • Images of Your Insurance Card (front and back):
    Providing images of both sides of your insurance card helps Medicare identify your specific coverage details accurately.

  • Chart Notes Reflecting Coverage Criteria: 
    Your doctor's notes serve as evidence to demonstrate that you meet Medicare's requirements for CGM coverage. Think of it as presenting supporting documentation to validate your claim for the CGM.

    For Medicaid, it's a state-by-state adventure!
    Some states offer full coverage for CGMs, while others might  limited coverage or require additional documentation for approval. 

    Check with your state Medicaid office or your Medicaid managed care plan for details on coverage and eligibility requirements.

    You can usually find contact information for your state Medicaid office on the Medicaid website of the U.S. Department of Health and Human Services (

How Can You Leverage Your Insurance for a Dexcom CGM When Purchasing From an Online Store?

While Dexcom CGMs are fantastic tools for diabetes management, it's important to understand that insurance typically won't reimburse purchases directly from online stores. Here's why:

  • Maintaining Quality Control: Insurance companies have strict guidelines about covered medical devices. They partner with specific suppliers to ensure quality and safety standards are met.

  • Fraud Prevention: Reimbursing online purchases opens the door to potential fraud. Insurance companies rely on verified suppliers to avoid covering counterfeit devices.

So, how can you leverage your insurance for a Dexcom CGM?

Here's a step-by-step guide:

Step 1: Check Your Coverage:

  • Review your insurance plan documents (or call your provider) to understand your coverage details for Dexcom CGMs. This includes:

    • Deductible: The amount you pay upfront before insurance kicks in.

    • Copay: A fixed amount you pay per CGM sensor or transmitter.

    • Coverage percentage: The portion of the cost your insurance covers after your deductible is met.

Step 2: Work with Your Doctor:

  • Schedule an appointment with your doctor to discuss your interest in Dexcom CGM.

  • Your doctor will assess your needs and determine if Dexcom CGM is right for you.

  • If approved, your doctor will provide a prescription specifying the Dexcom CGM model and supplies you need.

Step 3: Utilize Approved Suppliers:

  • Don't head straight to online retailers! Your doctor or insurance company might have preferred suppliers for Dexcom CGMs.

  • These suppliers will work directly with your insurance to handle billing and ensure coverage is applied.

Step 4: Submit for Reimbursement (Optional):

  • In some cases, your doctor's office might not handle insurance directly for CGMs.

  • If this applies to you, carefully review your insurance provider's instructions on submitting claims for reimbursement after purchasing from an approved supplier.
