Does insurance cover dexcom g6?

Whether insurance covers the Dexcom G6 continuous glucose monitoring (CGM) system depends on your specific insurance plan and provider. However, many insurance plans, including Medicare and Medicaid, do offer coverage for the Dexcom G6. Here’s a detailed overview of how insurance coverage for the Dexcom G6 typically works

Private Insurance
  1. Coverage Policies:

    • Varies by Plan: Coverage for the Dexcom G6 under private insurance varies widely by plan and provider. It’s important to check with your specific insurance company to determine if the Dexcom G6 is covered under your policy.
    • Durable Medical Equipment (DME): Some insurers classify the Dexcom G6 as durable medical equipment (DME), which may be covered under your health plan’s DME benefits.
  2. Prior Authorization:

    • Medical Necessity: Many insurance companies require prior authorization, which means your healthcare provider must demonstrate that the Dexcom G6 is medically necessary for managing your diabetes.
    • Supporting Documentation: Your healthcare provider will need to provide supporting documentation, such as your diabetes diagnosis, history of blood glucose control issues, and reasons why a CGM system is necessary.
  3. Cost and Co-Pays:

    • Out-of-Pocket Costs: If covered, the amount you pay out-of-pocket will depend on your plan’s coverage rules, co-pays, deductibles, and co-insurance. Some plans may cover the entire cost, while others might require you to pay a portion.

  1. Eligibility:

    • Type 1 and Type 2 Diabetes: Medicare covers the Dexcom G6 CGM system for beneficiaries with Type 1 or Type 2 diabetes who meet certain criteria.
    • Insulin Dependence: Typically, you must be insulin-dependent and require frequent adjustments to your insulin regimen to qualify.
  2. Medicare Part B:

    • DME Coverage: The Dexcom G6 is covered under Medicare Part B as durable medical equipment (DME).
    • Requirements: You must have a physician’s prescription and meet specific criteria, such as needing to check blood sugar levels four or more times a day and requiring multiple daily injections of insulin or an insulin pump.
  3. Costs:

    • 20% Co-Insurance: Medicare Part B usually covers 80% of the approved amount for DME after you meet the annual deductible. You are responsible for the remaining 20% as co-insurance.
    • Supplemental Insurance: If you have a Medigap policy or other supplemental insurance, it may cover the 20% co-insurance.

  1. State Variations:

    • State-Specific Programs: Medicaid coverage for the Dexcom G6 varies by state because Medicaid is administered at the state level. Some states cover CGM systems like the Dexcom G6, while others may have more limited coverage.
    • Eligibility and Criteria: Eligibility requirements and coverage criteria can differ significantly between states.
  2. Medical Necessity:

    • Physician Documentation: Similar to private insurance, Medicaid programs often require documentation from your healthcare provider to establish medical necessity for the Dexcom G6.

Tips for Securing Coverage
  1. Check with Your Insurer:

    • Direct Inquiry: Contact your insurance company directly to ask if the Dexcom G6 is covered under your plan and what the specific requirements are for coverage.
    • Plan Documents: Review your plan’s benefits documents or online portal for information on DME and CGM coverage.
  2. Work with Your Healthcare Provider:

    • Prior Authorization: Ensure your healthcare provider is familiar with the prior authorization process and can provide the necessary documentation to support your claim.
    • Medical Necessity Letter: A detailed letter from your healthcare provider explaining the medical necessity of the Dexcom G6 can be crucial for obtaining coverage.
  3. Appeal Denials:

    • Appeal Process: If your initial request for coverage is denied, you have the right to appeal the decision. Work with your healthcare provider to gather additional documentation and evidence to support your case.


Insurance coverage for the Dexcom G6 CGM system varies depending on your specific insurance plan, whether it’s private insurance, Medicare, or Medicaid. It’s essential to check with your insurance provider to understand the coverage details, potential out-of-pocket costs, and the necessary steps for prior authorization. If you face a denial, you can appeal the decision with additional supporting documentation from your healthcare provider.
