Prenatal Care Denied by Insurance? Know Your Rights and Appeal

Prenatal care is among the most critical medical services a pregnant person can receive. Regular prenatal visits, screenings, and vaccinations directly reduce maternal and infant mortality. Under the Affordable Care Act, most prenatal care must be covered at zero cost-sharing. Yet insurance denials and billing disputes during pregnancy are shockingly common. Here's how to fight back.

What Prenatal Care Is Covered Under the ACA

The ACA requires non-grandfathered health plans to cover USPSTF A and B-rated preventive services with no cost-sharing. HRSA's Women's Preventive Services Guidelines, incorporated into ACA requirements, add a broad set of prenatal services.

The following prenatal services must be covered at no cost to you:

• Prenatal visits: All recommended prenatal office visits, including initial obstetric intake
• Gestational diabetes screening: USPSTF B recommendation for gestational diabetes screening after 24 weeks
• Anemia screening: Iron deficiency anemia screening in pregnant women
• Hepatitis B and C screening: Covered for all adults including pregnant women
• HIV screening: Covered for pregnant women
• Syphilis and other STI screening: Covered as preventive during pregnancy
• Depression screening: Covered for pregnant and postpartum women (USPSTF B)
• Folic acid supplementation: Covered for women planning or capable of pregnancy
• Tdap (tetanus, diphtheria, pertussis) vaccine: Recommended during every pregnancy
• Flu (influenza) vaccine: Recommended annually, especially during pregnancy
• Rh incompatibility screening: Covered for pregnant women

Common Prenatal Care Denial Scenarios

Vaccines During Pregnancy Denied

Tdap vaccination during each pregnancy is recommended by the CDC and ACOG specifically to protect newborns from whooping cough before they can be vaccinated themselves. Flu shots are similarly recommended. Both should be covered at zero cost-share as preventive services. If your insurer billed your pregnancy vaccination as a regular office visit charge or denied it outright, appeal citing the CDC immunization schedule and HRSA Women's Preventive Services Guidelines.

Gestational Diabetes Screening Billed with Cost-Share

Gestational diabetes screening is a USPSTF B recommendation. Under the ACA, it must be covered with no cost-sharing. If your insurer billed you a copay or applied your deductible to the glucose tolerance test, that is an ACA violation. Keep your EOB and appeal with a citation to the USPSTF B rating.

Out-of-Network OB Provider Denials

If your OB-GYN is out-of-network, your plan may impose significantly higher cost-sharing or refuse to cover certain services. However, the ACA requires that plans provide access to in-network obstetric providers. If your plan has no in-network OB within a reasonable distance, or if your OB was previously in-network when you became pregnant and then left the network mid-pregnancy, your insurer may be required to provide continuity of care.

Mid-pregnancy network change: If your OB-GYN left your plan's network while you were already in an active course of treatment (pregnancy), most states and the ACA's continuity of care provisions allow you to continue with your OB at in-network rates through the postpartum period.

Hospital vs. Birth Center Disputes

If you plan to deliver at a birth center rather than a hospital, coverage disputes are common. The ACA requires coverage for labor and delivery; the setting (hospital vs. accredited birth center) should not determine coverage. Accredited freestanding birth centers are legitimate delivery settings. If your plan denies birth center delivery, appeal citing your plan's maternity coverage language and the fact that the facility is accredited.

Routine Prenatal Visit Charged as Office Visit

Insurers sometimes apply office visit copays to prenatal visits that should be billed as zero-cost preventive care. This happens because of how the visits are coded. If you were charged for a routine prenatal checkup, check whether the billing code used was a preventive code (e.g., 99381–99397 series) or an evaluation and management code. A preventive-coded prenatal visit should carry no cost-share.

How to Appeal a Prenatal Care Denial

Step 1: Collect your EOB and denial letter. Identify the specific service denied and the reason code used.

Step 2: Identify the ACA preventive service basis. Most prenatal services have USPSTF or HRSA backing. Look up the specific recommendation and its rating.

Step 3: Ask your OB to document medical necessity. For services that go beyond standard screening — such as additional ultrasounds or specialist visits — your OB-GYN should document the clinical indication.

Step 4: File your appeal within 180 days. Internal appeals must be filed within the timeframe specified in your denial letter, typically 180 days from the denial.

Step 5: Request expedited review if necessary. If you are currently pregnant, you are entitled to an expedited appeal turnaround — typically 72 hours for urgent situations.

Step 6: Contact your state insurance commissioner. Prenatal care denials that violate the ACA can be reported to your state's insurance regulatory authority or to HHS/CMS.
