Last reviewed August 20, 2026 by the Medically Modern coverage team. State Medicaid policies change frequently — always confirm with your own state agency or plan.
The vast majority of state Medicaid programs now cover continuous glucose monitors. What does not exist is a consistent national Medicaid CGM policy. The Center for Health Care Strategies, which tracks this state by state, found in its most recent comprehensive count (May 2023) that 45 states and the District of Columbia provided some level of fee-for-service CGM coverage, while five states provided none. States have continued expanding since then.
Why we date that figure: it is the most recent comprehensive multi-state count we can point to, and presenting it as a current-year number would be misleading. Individual states have expanded since — Maryland, for example, expanded CGM coverage effective January 1, 2026 for UnitedHealthcare Community Plan members using insulin or with gestational diabetes or problematic hypoglycemic events. Check your own state rather than relying on any national tally.
What varies from state to state
- Who qualifies. Many states cover CGMs for insulin users. Some extend to people with problematic hypoglycemia, gestational diabetes, or type 2 diabetes not on insulin. Some restrict by age.
- Which brand. States and managed care plans often have a preferred CGM. A plan preferring another manufacturer may still approve a G7 with clinical justification, but it is an extra step.
- Prior authorization. Common, and the requirements differ. Some states need documented blood glucose testing frequency, an A1C threshold, or evidence of a diabetes education visit.
- Which benefit. Some states run CGMs through the pharmacy benefit, others through durable medical equipment. This determines who you order from.
- Quantity limits. How many sensors per month, and whether a 90-day supply is allowed.

Tell us your state and plan and we will find out what applies to you — no cost, no obligation.
What it costs
Medicaid cost sharing is low by design. Many states charge nothing for covered DME and supplies; others charge a small nominal copay. Compared with the $180–$320 a month that cash payers face with a discount card, Medicaid coverage is by far the better outcome when you can get it — which is why the effort belongs in getting approved rather than in hunting for coupons.
Coupons and Medicaid do not mix
- Federal anti-kickback rules prohibit manufacturer coupons and copay assistance for Medicaid beneficiaries.
- Dexcom's free trial explicitly excludes government health plans, Medicaid among them.
- Dexcom's pharmacy savings coupon requires opting out of insurance for that fill — giving up Medicaid coverage to pay cash would almost always cost you more.
If you are on Medicaid and a website offers you free Dexcom sensors, treat it as a red flag rather than an opportunity.
If your state denies the G7
Get the denial in writing
You are entitled to a written notice stating the specific reason and your appeal rights.
Check whether it is a brand preference
If the plan prefers a different CGM, your prescriber can request an exception with clinical justification — or you and your doctor may decide the preferred device is fine.
Fill documentation gaps
Most denials are about missing chart notes: insulin regimen, hypoglycemia history, recent visits. Your prescriber supplies them and resubmits.
Use the fair hearing process
Every state Medicaid program has an appeals and fair hearing process with deadlines. Do not let them lapse while waiting on a phone call.
Dual eligibility: Medicare and Medicaid together
If you have both Medicare and Medicaid, Medicare is generally the primary payer for a CGM and Medicaid may cover some or all of what Medicare leaves — including the Part B coinsurance. That means your out-of-pocket cost can be very low. The catch is that you must still satisfy Medicare's coverage criteria, including its six-month visit requirement, because Medicare rules govern the primary claim.
Frequently asked questions
Does Medicaid cover CGMs for type 2 diabetes?
In many states, yes, particularly for people using insulin. Coverage for type 2 diabetes without insulin is less consistent and is exactly the kind of thing that varies most from state to state. Check your state's policy.
Does Medicaid cover the Dexcom G7 15 Day?
That depends on whether your state or plan has added it. Newer products take time to appear on preferred lists even when the standard G7 is already covered, so ask about the specific product rather than about Dexcom generally.
I have Medicaid managed care, not straight Medicaid. Does that change things?
Often yes. Managed care organizations set their own preferred products and prior-authorization rules within the state's framework. The plan's member services line, not the state agency, is usually the faster answer.
How to find your own state's policy
National summaries are useful for orientation and useless for your actual order. Here is how to get to the rule that governs you:
Work out whether you are in fee-for-service or managed care
Your Medicaid card usually names a managed care organization if you are in one. If it does, that plan's rules govern day to day, within the state's framework.
Search for your state's preferred drug list or DME fee schedule
Search terms that work: your state name plus “Medicaid preferred drug list continuous glucose monitor” or “Medicaid DME fee schedule CGM.” States publish these, though they are not always easy reading.
Call member services and ask the specific questions
Is a CGM covered? Is the Dexcom G7 preferred or non-preferred? Is prior authorization required and what criteria apply? Pharmacy benefit or DME? How many sensors per month?
Ask your prescriber's office what they have seen recently
Clinics that treat a lot of Medicaid patients often know the current practical answer faster than the published policy does.
What state programs typically want documented
Criteria vary, but the recurring themes across states are consistent enough to prepare for:
- A diabetes diagnosis with the diagnosis code on the order.
- Insulin use, often with the regimen specified, or documented hypoglycemia — many states borrow Medicare's framing of recurrent lows below 54 mg/dL or a severe event needing third-party help.
- Evidence of engagement with care: recent visits, sometimes a diabetes education visit, sometimes documented self-monitoring frequency.
- Sometimes an A1C threshold, which Medicare does not use but some states do.
- A prescription naming the specific product and quantity.
Prepare for prior authorization before it is requested. If your prescriber documents the insulin regimen and any hypoglycemic events clearly at the visit where the CGM is first discussed, the authorization usually goes through on the first submission instead of bouncing.
Managed care versus fee-for-service
Most Medicaid beneficiaries are now in managed care, and this matters practically. The state sets a floor of covered benefits; the managed care organization decides its preferred products, its prior-authorization process, and its supplier network within that floor. So “my state covers CGMs” and “my plan will approve a Dexcom G7 from this supplier” are genuinely different statements, and only the second one gets sensors to your door.
If your plan prefers a different CGM brand, a formulary exception with clinical justification is the route — the same mechanism commercial plans use, described on our insurance page.
Children and CHIP
Coverage for children may run through Medicaid or through your state's Children's Health Insurance Program, and the CGM rules are not always identical. One product note matters here regardless of payer: the Dexcom G7 15 Day is cleared for adults 18 and over, so pediatric patients use the standard Dexcom G7. Make sure the prescription names the right product for the patient's age — a mismatch is an avoidable rejection. See the comparison page.
If your coverage changes
Medicaid eligibility is redetermined periodically, and coverage can lapse for paperwork reasons while you still qualify. Because a CGM is an ongoing supply rather than a one-time purchase, a lapse shows up as a missed refill. If you get a redetermination notice, deal with it before it affects your sensor supply, and tell your supplier if there is a gap so they are not billing a plan that has terminated.
