The 30-second version
- Dexcom's Savings Center is a pharmacy cash coupon, used outside insurance, plus a separate PAP for eligible patients
- Abbott's savings pathway applies to commercially insured or uninsured patients paying more than a set amount per sensor box
- Medicare Part B may cover a CGM when a clinician orders it and you use insulin or have a history of problematic hypoglycemia
- Medicaid CGM coverage and billing routes vary by state. Check your state's preferred-drug list and DME manual
When a CGM is unaffordable, first figure out whether the problem is no coverage, a high deductible, the wrong benefit channel, or a claim error. The fix is different in each case.
Dexcom
Dexcom's Savings Center currently describes a pharmacy cash coupon for people with a prescription who lack coverage or have a high copay. It's used outside insurance and therefore doesn't reduce an insurance copay or deductible. Dexcom also offers a separate Patient Assistance Program for eligible U.S. residents who meet its criteria. Use the current application rather than assuming last year's income or insurance rules still apply.
Abbott FreeStyle Libre
Abbott says eligible commercially insured or uninsured patients asked to pay more than $75 for two FreeStyle Libre 3 Plus or Libre 2 Plus sensors may use its savings pathway. Federal and state program beneficiaries are excluded. Confirm the covered sensor, pharmacy, quantity, and current terms.
Medicare
Medicare Part B may cover a CGM and related supplies when a clinician orders it and the beneficiary uses insulin or has a qualifying history of problematic hypoglycemia. The patient or caregiver has to be trained, and the supplier and clinician have to meet Medicare requirements. After the Part B deductible, the usual patient share is 20% of the Medicare-approved amount. Ask the supplier whether it accepts assignment.
Medicaid
Coverage and billing route vary by state. Search the state Medicaid preferred-drug list, DME manual, and CGM prior-authorization criteria. Then ask whether the product is processed through pharmacy or medical benefits and whether the state managed-care plan adds its own form.
The access gap
CGM access is unequal across race and insurance type, and navigation can close part of that gap, but it isn't the only cause. Prescribing patterns, coverage design, language, trust, supply access, and structural inequity all play a role. Don't treat the entire disparity as a paperwork problem.
If denied, request the criteria and appeal with insulin use, hypoglycemia history, glucose records, training, and the precise clinical need.

Biosimilar and unbranded insulins: are they actually the same?
"Generic insulin" can mean several different things, and the labels matter for switching and pricing.
Insulin is not the whole diabetes bill
A person can get insulin for $35 and still not afford the tools needed to dose it safely.
