Most routine prenatal visits are covered at no cost to you under the Affordable Care Act. Insurance plans are required to cover preventive prenatal care, including standard office visits, without charging a copay, coinsurance, or deductible. But “prenatal care” involves more than just checkups, and the services that fall outside that preventive umbrella can add up. Women with employer-sponsored insurance pay an average of $2,743 in additional out-of-pocket costs over the course of a pregnancy, according to Peterson-KFF Health System Tracker data from 2021 to 2023.
What Insurance Must Cover at Zero Cost
Under the ACA, most health plans must cover a set of preventive prenatal services with no cost-sharing at all. That means no copay at the front desk, no portion applied to your deductible, and no coinsurance bill afterward. The covered services include routine prenatal office visits, gestational diabetes screening (typically between 24 and 28 weeks), HIV screening at the start of prenatal care, anxiety screening during and after pregnancy, and breastfeeding support including a breast pump.
This applies to most employer-sponsored plans, marketplace plans, and plans sold directly by insurers. Grandfathered plans (those that existed before the ACA took effect in 2010 and haven’t changed significantly) may not follow these rules, so it’s worth checking if yours is one.
Where Out-of-Pocket Costs Come From
The $0 coverage applies specifically to preventive visits and screenings. Many other pregnancy-related services are treated as diagnostic or medical care, which means your plan’s normal cost-sharing kicks in. These are the costs that drive that $2,743 average.
Ultrasounds are a common source of bills. A standard anatomy scan around 20 weeks and early dating ultrasounds may be subject to your deductible or coinsurance, depending on how your plan classifies them. Blood work beyond the standard preventive screenings, specialist referrals for high-risk pregnancies, and any additional monitoring can also generate separate charges. Each of these services gets billed through your plan’s usual structure: you pay your deductible first, then typically a percentage (coinsurance) or flat fee (copay) for each service until you hit your out-of-pocket maximum.
Genetic Testing Can Be a Surprise Bill
Non-invasive prenatal testing (NIPT), the blood draw that screens for chromosomal conditions like Down syndrome, is one of the most variable costs in prenatal care. Coverage depends heavily on your insurer and your risk profile. Major insurers like Anthem, Aetna, and Cigna cover NIPT for all single pregnancies. Others, like TRICARE and Molina Healthcare, only cover it for high-risk pregnancies, such as when the mother is 35 or older, has a history of chromosomal conditions, or had an abnormal result on earlier screening.
Some insurers also require prior authorization before the test. UnitedHealthcare and the federal employee Blue Cross Blue Shield plan, for example, both require approval in advance. If you skip that step, you could be responsible for the full cost. Before scheduling NIPT, call your insurer to confirm whether it’s covered for your specific situation and whether you need authorization.
How Your Plan Type Affects Costs
If you’re on a high-deductible health plan (HDHP), you might assume you’ll pay full price for everything until your deductible is met. For prenatal care, that’s often not the case. Many HDHPs exempt routine prenatal and postpartum visits from the deductible entirely, offering first-dollar coverage or low copays for checkups, fetal ultrasounds, routine urinalysis, and STI screenings. The deductible still applies to non-preventive services like lab work classified as diagnostic, hospital-based procedures, or specialist visits.
On a PPO or HMO with a lower deductible, you’ll typically meet that threshold earlier in your pregnancy, which means coinsurance (often 10% to 20% for in-network care) takes over sooner. Either way, your out-of-pocket maximum is the ceiling. Once you hit it, your plan covers 100% of in-network costs for the rest of the plan year.
When You Deliver Matters More Than You’d Think
A pregnancy almost always spans two calendar years, and that timing can significantly affect what you pay. Your deductible and out-of-pocket maximum reset on January 1 in most plans. Research from the USC Schaeffer Center found that women delivering in January paid an average of $6,308 in cost-sharing for pregnancy, delivery, and three months postpartum, compared to $4,998 for women delivering in December. That’s a $1,310 difference for essentially the same care, driven entirely by the calendar reset forcing patients to satisfy their deductible twice.
This effect is strongest on high-deductible plans. If your due date is near the end of December or early January, it’s worth understanding where you’ll stand with your deductible in each calendar year. You can’t control when your baby arrives, but knowing this pattern helps you budget more accurately.
How Prenatal Billing Works
Many OB-GYN practices use “global billing,” which bundles all your prenatal visits, delivery, and hospital discharge into a single charge. Under this model, you typically won’t see individual bills for each office visit. Instead, the practice submits one claim after delivery that covers the entire course of care, usually requiring at least 8 to 13 prenatal visits to qualify.
Some practices bill per visit instead, especially if you switch providers mid-pregnancy or if a different doctor handles your delivery. Per-visit billing can make costs feel more transparent since you see charges as they happen, but the total tends to be similar. Either way, lab work, imaging, and screenings ordered during those visits are almost always billed separately from the office visit itself, which is why you may receive bills from labs or radiology groups you’ve never heard of.
Medicaid Covers Prenatal Care Differently
If you qualify for Medicaid, prenatal care is effectively free. Federal rules exempt pregnant women from most out-of-pocket costs, meaning no copays or coinsurance for prenatal visits, lab work, or delivery. Many states also have expanded Medicaid eligibility specifically for pregnant women, covering individuals with household incomes well above the standard Medicaid threshold. If your income has changed or you’ve recently become pregnant, it’s worth checking whether you qualify, even if you didn’t before.
Keeping Your Costs Down
Stay in-network for every service you can control. Your OB may be in-network, but the lab they send your blood work to might not be. Ask before any test is ordered. Request that your provider use in-network labs and imaging centers, and confirm coverage for any genetic testing before it’s performed.
Review your plan’s summary of benefits for maternity care specifically. Many insurers list prenatal care as a separate category with its own cost-sharing rules. If your employer offers a choice of plans during open enrollment and you’re planning a pregnancy, compare the total expected cost: a plan with higher premiums but a lower deductible and out-of-pocket maximum can save you money overall when you factor in delivery. The math changes when you’re expecting $10,000 or more in total billed charges rather than a typical year of occasional doctor visits.
