- A basic glucose meter (the kind you prick your finger and test on) costs $15–$50 to buy, and test strips run $0.50–$1.50 per strip.
- The National Diabetes Prevention Program is a year-long group-based lifestyle program (16 sessions over 6 months, then 6 monthly maintenance sessions) that has been shown in trials to reduce progression.

Out-of-pocket costs for prediabetes care
You got the call or the portal message, and the first question after "what is prediabetes" is usually "what does this cost me?" It's practical and fair — you're already processing the diagnosis, and now you need to know if prevention fits your budget.
The out-of-pocket reality depends on your insurance, your location, and which parts of care you pursue. But the good news is that the most effective interventions — the ones proven to work — are either low-cost or covered by many plans.
What does an A1C test cost out of pocket?
A single A1C test typically costs $25–$50 out of pocket if you have insurance and meet your deductible, or $50–$150 if you're uninsured and paying cash. Many insurance plans cover annual A1C screening at no cost to you (as a preventive service), so your actual out-of-pocket cost may be zero.
The variation depends on whether your plan classifies the test as preventive (covered in full) or diagnostic (subject to your deductible and copay). Your best move: call your insurance company or check your online portal before the test to confirm your cost. If you're uninsured, ask your clinic or lab about sliding-scale fees or community health center options — many offer prediabetes screening at reduced rates.
Most insurance plans cover at least one A1C test per year as preventive care, which means no out-of-pocket cost to you.
How much does glucose monitoring cost?
A basic glucose meter (the kind you prick your finger and test on) costs $15–$50 to buy, and test strips run $0.50–$1.50 per strip. If you test once daily, that's roughly $15–$45 per month for strips alone.
Most insurance plans do not cover meters and strips for prediabetes unless you're on certain medications (like metformin or insulin). If you're uninsured or your plan doesn't cover them, you can reduce cost by testing less frequently — discuss with your clinician which days or times matter most for your situation. Walmart ReliOn meters and strips are among the cheapest options available without insurance.
Continuous glucose monitors (CGMs) are more expensive ($200–$400 per month with sensors and supplies) and are rarely covered by insurance for prediabetes; they're typically reserved for people on insulin. If you're interested in home glucose monitoring, discuss which tool and testing frequency make sense for your plan and budget with your doctor first.

What does the National Diabetes Prevention Program cost?
The National Diabetes Prevention Program is a year-long group-based lifestyle program (16 sessions over 6 months, then 6 monthly maintenance sessions) that has been shown in trials to reduce progression. Many programs are free or low-cost ($0–$150 per participant) because they're funded by public health agencies, employers, or insurance companies.
Medicare covers its version of the program (called the Medicare Diabetes Prevention Program) at no cost to eligible beneficiaries. Many private insurers also cover it fully or in part. If you're uninsured, community health centers and some nonprofits offer CDC-recognized programs at sliding-scale fees. Your clinician or your insurance company can help you find a program near you and confirm what you'll pay.
- Free or low-cost through Medicare, many private plans, and community health centers
- Year-long commitment with proven ~58% reduction in progression in trials
- Group-based format (typically 10–15 people) — some programs also offer online options
- Ask your insurance or primary care clinic for a referral to a local program
The most effective intervention — lifestyle change through a structured program — is often free or covered by insurance.
What about dietitian visits and other appointments?
A single visit with a registered dietitian (Registered Dietitian Nutritionist, or RDN) costs $100–$300 out of pocket if uninsured, or a copay of $25–$75 if you have insurance. Some plans cover 3–6 dietitian visits per year as part of preventive care or medical nutrition therapy (MNT); others cover none.
Check your plan's coverage for "medical nutrition therapy" or ask your primary care doctor for a referral — many practices have in-house dietitians or can refer you to one your insurance recognizes. If cost is a barrier, ask your doctor about group nutrition classes, which are often cheaper than one-on-one visits.
Routine follow-up visits with your primary care doctor (to recheck your A1C, usually annually) are typically covered like any other office visit — subject to your copay or deductible. These appointments are important for monitoring your numbers over time, so budget for them as you would any preventive care.
How can you reduce out-of-pocket costs?
Start by understanding what your insurance covers: call your plan's member services line and ask specifically about A1C testing, dietitian visits, and diabetes prevention programs. Many plans have preventive benefits you may not know about.
Use community resources: federally qualified health centers (FQHCs) offer sliding-scale fees based on income, and many CDC-recognized prevention programs are free. Your primary care clinic can also point you toward no-cost or low-cost screening events in your area.
If you're uninsured, ask about cash-pay discounts at labs and clinics — many offer 20–40% reductions if you pay upfront. Some employers and health plans now cover the National Diabetes Prevention Program at no cost as a perk; check your benefits summary or employee portal.
- Verify your insurance coverage before testing or appointments
- Ask your doctor about free or low-cost prevention programs in your community
- Look into community health centers and sliding-scale clinics if uninsured
- Employer-sponsored programs often cover prevention at little or no cost — check your benefits
