| No insurance | Not covered by an insurer | Self-pay price, free screening events, membership |
What Counts as Diabetes Screening?
Screening means testing people who have no symptoms, to find prediabetes or type 2 diabetes early. Three blood tests are commonly used:
- A1C (HbA1c): shows your average blood sugar over about the past three months. It generally doesn’t require fasting.
- Fasting plasma glucose: measures blood sugar after you’ve gone without food, usually 8 to 12 hours.
- Oral glucose tolerance test (OGTT): measures how your body handles a measured sugar drink over time.
Screening is different from diagnosis. If you already have symptoms or a prior abnormal result, the test is usually billed as diagnostic, and that changes what you pay.
Who Qualifies for Covered Diabetes Screening?
The U.S. Preventive Services Task Force (USPSTF) gives screening a Grade B recommendation for adults aged 35 to 70 who have overweight or obesity (a BMI of 25 or higher) and no diabetes symptoms. A B grade matters because the Affordable Care Act generally requires plans to cover Grade A and B preventive services without cost sharing. The Task Force lowered the starting age from 40 to 35 in 2021. If your result is normal, repeating the test every three years may be reasonable. Your provider may suggest a different schedule based on your risks.
You may be screened earlier or sooner if you have higher risk, such as a family history of diabetes, a history of gestational diabetes, or membership in a higher-risk group. The American Diabetes Association also uses a lower BMI threshold of 23 for Asian American adults. Whether a plan pays for earlier screening follows the plan’s own rules, so check before you go.
Medicare lists risk factors such as high blood pressure, abnormal cholesterol, obesity, a history of high blood sugar, a family history of diabetes, or a history of gestational diabetes. Your provider determines whether you qualify.
How Each Type of Insurance Handles Diabetes Screening
Private and employer plans. Most ACA-compliant plans must cover USPSTF-recommended screening with no copay or deductible when you’re eligible and use an in-network provider. Grandfathered plans and some short-term or limited plans can work differently, so read your benefits.
Original Medicare (Part B). Medicare covers up to two blood glucose screenings a year if your provider determines you’re at risk. You pay nothing if your provider accepts assignment. Since January 1, 2024, the A1C test counts as a covered screening test, in addition to fasting glucose and glucose tolerance tests. Because A1C doesn’t require fasting, it’s often easier for patients.
Medicare Advantage. These plans must cover what Original Medicare covers, but networks, referrals and prior authorization rules differ. Confirm the clinic is in your plan’s network.
Medicaid. Coverage depends on your state and plan. We don’t want to guess about your specific plan, so call your plan or our team to verify.
No insurance. An insurer won’t pay, but you still have options. Ask about free screening events, self-pay pricing and membership plans.
Why You Might Still Get a Bill: Screening vs. Diagnostic
The same blood test can be billed two ways. What decides it is why the test was ordered, not the test itself.
| Situation | Usually billed as | Typical result |
|---|---|---|
| Routine A1C, no symptoms, you meet screening criteria | Preventive screening | Often $0 in network |
| A1C ordered because of thirst, fatigue or other symptoms | Diagnostic | Deductible or coinsurance may apply |
| Repeat A1C to monitor known diabetes | Diagnostic/monitoring | Cost sharing usually applies |
| Extra tests added to the same draw (cholesterol, metabolic panel) | Each billed separately | Each may be covered differently |
| Office visit to discuss symptoms or manage a condition | Office visit | A visit charge may apply |
A common surprise: you go in for a free screening, mention a symptom, and the visit is billed as diagnostic. If you’re symptom-free and eligible, ask how the test will be coded before it’s drawn.
How to Check Your Coverage Before You Go
- Call the number on your insurance card and ask: “Is a diabetes screening covered as a preventive service for me, and at what cost?”
- Ask about the test by name (A1C, fasting glucose or glucose tolerance test) and whether it’s covered as a screening.
- Confirm the clinic is in your network.
- Ask how often your plan covers screening and whether you’ve already used it this year.
- Ask the clinic how the test will be coded (preventive or diagnostic) before your blood is drawn.
Providers commonly use screening diagnosis code Z13.1 for diabetes screening, so you can mention it when you call. Not sure what to bring? Read our guide on how to prepare for a preventive health screening.
What Do Screening Results Mean?
A1C results are generally read like this:
- Below 5.7%: normal
- 5.7% to 6.4%: prediabetes
- 6.5% or higher: in the diabetes range
An abnormal screening result doesn’t automatically mean you have diabetes. Your provider may order a confirming test and discuss next steps. Our guide on A1C vs. fasting blood sugar explains how the tests differ.

When to See a Provider Instead of Getting a Screening
Screening is for people without symptoms. If you have extreme thirst, frequent urination, unexplained weight loss, blurry vision or unusual fatigue, you need an evaluation, not a routine screening. Our urgent care team can see you for non-life-threatening concerns. For severe symptoms such as confusion, trouble breathing or chest pain, call 911.
FAQs
Is diabetes screening covered by insurance?

Does Medicare cover diabetes screening?
