Last reviewed August 13, 2026 by the Medically Modern coverage team. Coverage rules change — always confirm with your plan.
Qualifying for a FreeStyle Libre® sensor through insurance comes down to four things: a diabetes diagnosis, either insulin use or a documented history of serious low blood sugar, a recent visit with your diabetes provider, and a plan that covers continuous glucose monitors (CGMs). Medicare, most state Medicaid programs, and more than 95% of commercial plans cover FreeStyle Libre for people who meet their criteria.
The exact rules differ by payer, but they overlap far more than they differ. Run through the self-check below, then see the payer-specific requirements underneath. These are insurance rules, not medical advice — talk with your doctor about whether a CGM fits your treatment plan.
The quick self-check: 4 questions
Answer honestly — there’s no score to game, and “not yet” on one question usually just means one extra step, not a dead end.
- 1. Have you been diagnosed with diabetes? Type 1, type 2, or gestational — Medicare’s criteria apply to diabetes of any type. What matters more is the next question.
- 2. Do you use insulin — or have you had serious low-blood-sugar events? Any insulin counts, including a single long-acting shot a day. If you don’t use insulin, documented severe or recurring lows can also qualify you under Medicare’s rules.
- 3. Have you seen your diabetes provider in the last 6 months — or are you willing to? Medicare requires an in-person or telehealth visit within the 6 months before the order. If it’s been longer, a scheduled appointment fixes it.
- 4. Do you have insurance — Medicare, Medicaid, or a commercial plan? Medicare Part B covers CGMs as durable medical equipment, most state Medicaid programs cover them, and Abbott reports over 95% of commercial plans do too.
Mostly yes? You’re a strong candidate. The fastest way to confirm is a benefits check — our team contacts your insurer, reads your actual plan rules, and tells you what you’d pay before anything is ordered.

Requirements by insurance type
Medicare
Medicare Part B covers FreeStyle Libre under a Medicare coverage policy (LCD L33822). You qualify for initial coverage if all of the following are true:
- You have a diagnosis of diabetes mellitus — any type.
- You meet one of two paths: (a) you are treated with insulin, or (b) you have a documented history of problematic hypoglycemia — either recurrent lows below 54 mg/dL that persisted despite multiple adjustments to your medications or treatment plan, or one severe low (below 54 mg/dL with altered mental or physical state) that required another person’s help.
- You had an in-person or Medicare-approved telehealth visit with your treating practitioner within the 6 months before the order.
- Your practitioner confirms you (or your caregiver) have sufficient training to use the device, and it’s used as FDA-indicated.
To keep coverage going, Medicare also requires a follow-up visit every 6 months. After the 2026 Part B deductible of $283, you typically pay 20% coinsurance when your supplier accepts assignment — and a Medigap plan may cover that share. Full details — including billing and follow-up rules — are in our Medicare coverage guide.
Medicaid
Medicaid rules are set state by state. As of the most recent 50-state census, 45 states plus D.C. cover CGMs at some level, and children under 21 qualify in every state when a CGM is medically necessary (through the EPSDT benefit). Typical adult criteria look a lot like Medicare’s: a diabetes diagnosis plus insulin use, with prior authorization required in most states — though several states have dropped prior authorization for preferred CGM brands. Some states also cover gestational diabetes or non-insulin users with hypoglycemia. See our Medicaid coverage guide for how your state handles it.
Commercial insurance
Abbott reports that more than 95% of private plans cover FreeStyle Libre, and most covered patients pay $0–$20 per month for sensors. Type 1 diabetes is usually approved with no extra criteria. For type 2, plans typically require insulin use — and some current policies also accept an injectable GLP-1 medication — along with supporting documentation from your chart. Prior authorization is common, approvals typically last 12 months, and starting in late 2025 some plans began extending coverage to people with type 2 diabetes who don’t use insulin at all. Our private insurance guide walks through the prior-authorization process.
What you do not need
A lot of what people “know” about CGM requirements is out of date. None of the following will disqualify you:
- A minimum number of fingersticks per day. Medicare removed its fingerstick-frequency requirement — you no longer need to document daily fingerstick testing to qualify.
- Multiple daily injections. There is no injection-count minimum. One basal (long-acting) shot a day counts as insulin-treated under Medicare’s rules.
- Insulin, in every case. Type 2 without insulin can still qualify through Medicare’s hypoglycemia path, through some state Medicaid rules, or under the commercial plans that began covering non-insulin type 2 in late 2025.
- Being under a certain age. Medicare’s criteria have no upper age limit, and the current Libre 2 Plus and 3 Plus sensors are indicated for ages 2 and up.
Documentation your provider supplies (we collect it for you)
You don’t need to gather paperwork yourself — the documentation insurers want lives in your doctor’s chart, and Medically Modern requests it directly from your provider’s office. Here’s what payers look for:
- A visit note from the last 6 months showing your provider is managing your diabetes.
- Your diagnosis documented in the medical record.
- Your insulin regimen or hypoglycemia history — the chart detail that satisfies the “insulin or lows” requirement.
- A prescription and standard written order (SWO) for the sensor — and, for Medicare, the reader as well.
Why this matters: incomplete chart notes are one of the most common reasons CGM claims get denied. A supplier that collects the documentation up front — before shipping — protects you from surprise denials later.

Frequently asked questions
Can I qualify with type 2 diabetes if I don’t use insulin?
Sometimes, yes. Medicare covers CGMs for non-insulin users who have a documented history of problematic hypoglycemia — repeated readings below 54 mg/dL despite treatment changes, or one severe low that required someone else’s help. Some commercial plans also began covering type 2 non-insulin users in late 2025, and Medicaid rules vary by state. A benefits check is the quickest way to find out what your plan allows.
Does one long-acting insulin shot a day count as “insulin-treated”?
Yes — for Medicare, any insulin treatment qualifies. The rules set no minimum number of injections, so a once-daily basal dose counts. The old multiple-daily-injection requirement is gone. Commercial plans write their own criteria, and some still ask about your regimen during prior authorization.
Do I have to see my doctor before I can get FreeStyle Libre?
For Medicare, yes: an in-person or Medicare-approved telehealth visit within the 6 months before the order, plus a follow-up every 6 months to keep coverage active. If it’s been a while, scheduling a visit — telehealth counts — usually solves it. Most other payers also want recent chart notes behind the prescription.
Is there an age limit?
There’s no upper age limit in Medicare’s coverage criteria — people qualify in their 70s, 80s, and beyond. On the younger end, the current sensors are FDA-indicated for ages 2 and up, and every state Medicaid program covers medically necessary CGMs for children under 21 through EPSDT.
How much will it cost if I qualify?
It depends on your plan. With Original Medicare you typically pay 20% after the $283 Part B deductible (2026) — roughly $45–$55 a month without supplemental coverage, and often $0 with a Medigap plan. Abbott reports most commercially insured patients pay $0–$20 per month, and most Medicare Advantage patients pay $0, though every plan differs.
