Does Aetna Cover Genetic Testing During Pregnancy?

Aetna does cover genetic testing during pregnancy, including noninvasive prenatal testing (NIPT), carrier screening, first- and second-trimester serum screening, amniocentesis, chorionic villus sampling, and genetic counseling, as long as the specific test meets the medical necessity criteria in Aetna’s clinical policies.¹ Expanded panels that go beyond standard screening are generally excluded, and most tests are billed as diagnostic services, so you can expect them to run through your deductible and coinsurance rather than being free.

Noninvasive Prenatal Testing (NIPT)

Aetna considers NIPT medically necessary for all pregnant women, regardless of age or risk level, to screen for trisomy 13, 18, and 21 and for sex chromosome aneuploidy.¹ That’s a change from Aetna’s older policy, which limited NIPT to high-risk pregnancies before late 2020. The current rule aligns with the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine, which recommend offering cell-free DNA screening to every pregnant patient.²

There are two important limits. First, NIPT is not covered if you have already had a negative serum marker screening test (with or without nuchal translucency ultrasound) in the current pregnancy. Stacking screens is not considered medically necessary. Second, Aetna classifies expanded NIPT panels — screening for microdeletions, microduplications, and rare autosomal trisomies beyond 13, 18, 21, X, and Y — as experimental and does not cover them.¹ Single- and multi-gene prenatal cfDNA products such as PreSeek and Vistara fall into the same excluded category.

Aetna Medicaid Plans May Differ

Commercial Aetna plans follow the “all pregnant women” NIPT policy. Aetna’s Medicaid managed care plans can be stricter. A 2021 Aetna Better Health of Louisiana policy, for example, limited NIPT to women over 35 or those meeting specific high-risk criteria such as abnormal screening results, family history of aneuploidy, a prior pregnancy with aneuploidy, or a known parental translocation involving chromosomes 13 or 21, and excluded multiple gestations entirely.³ If you’re on a Medicaid-based Aetna plan, check your plan documents or call Member Services for the current criteria.

Carrier Screening

Carrier screening tells you whether you and your partner carry gene mutations that could pass to a child. Aetna covers it as medically necessary for people who are pregnant or planning a pregnancy when two conditions are met: the panel includes cystic fibrosis, spinal muscular atrophy, and/or hemoglobinopathies (unless you’ve already been tested), and the results will be used for pregnancy management, fetal treatment, or family planning.⁴

Two approaches are recognized. An expanded pan-ethnic panel testing 15 or more genes for recessive conditions with a carrier frequency of at least 1 in 200 is covered once per lifetime, in line with 2021 guidelines from the American College of Medical Genetics and Genomics. Targeted screening based on a known familial mutation or a specific gene tied to family history is also covered, but broader targeted screening beyond known mutations is not considered medically necessary. Repeat carrier screening — running the same panel again after a prior test — is classified as experimental and is not covered.⁴

Condition-Specific Rules

Aetna sets more specific criteria for several conditions. Cystic fibrosis carrier testing is covered for people and their reproductive partners who are pregnant, planning pregnancy, or have a relevant family history; Aetna covers the ACMG 25-mutation core panel and reserves full gene sequencing for symptomatic cases or ambiguous sweat chloride results. Hemoglobinopathy testing for sickle cell and thalassemia is covered for people planning pregnancy or at the initial prenatal visit if no prior results exist, though noninvasive prenatal diagnosis of sickle cell disease using cell-free fetal DNA is classified as experimental.⁴

Preconception or prenatal screening for the Ashkenazi Jewish ancestry panel of 14 conditions, including Tay-Sachs, Canavan disease, Bloom syndrome, Gaucher disease, Niemann-Pick, and cystic fibrosis, is covered. When only one partner has Ashkenazi Jewish ancestry, the other partner’s testing becomes medically necessary only if the first partner tests positive.⁴

FMR1 testing for Fragile X syndrome is covered for people planning pregnancy who have a family history of Fragile X, unexplained developmental delay, intellectual disability, autism, or primary ovarian insufficiency; if the mother tests positive, prenatal testing of the fetus through amniocentesis or CVS is covered. Population-wide Fragile X screening is experimental. Prenatal testing for Huntington disease is covered for fetuses from families with a history of the condition.⁴

First- and Second-Trimester Serum Screening

Aetna covers combined first-trimester screening, which pairs nuchal translucency measurement with the serum analytes PAPP-A and beta-hCG, along with integrated, sequential, and contingent approaches that combine first- and second-trimester results.⁵ Nuchal translucency measurement by itself is covered only in multiple gestations; for singleton pregnancies without cystic hygroma, NT alone is classified as experimental.

For the second trimester, Aetna covers the quad screen — maternal serum alpha-fetoprotein, unconjugated estriol, hCG, and inhibin A — for pregnant women who have received adequate counseling, want risk information about Down syndrome, and decline invasive diagnostic procedures.¹

The no-stacking rule cuts both ways. If you’ve already had NIPT or microarray analysis in the current pregnancy, serum screening afterward is not covered.⁵ If you’ve already had a negative serum screen, NIPT on top of it is not covered either.¹ Pick one path with your provider.

Amniocentesis, CVS, and Other Diagnostic Procedures

When screening results are abnormal or other risk factors exist, Aetna covers invasive diagnostic procedures as medically necessary. That includes genetic amniocentesis, chorionic villus sampling, and percutaneous umbilical blood sampling (cordocentesis) for diagnosing fetal chromosomal abnormalities.⁶ Conventional cytogenetic analysis and rapid testing by quantitative fluorescent PCR are both covered when there is an increased risk of aneuploidy, fetal ultrasound abnormalities (including an NT measurement above 3.5 mm), or a known familial chromosomal rearrangement.

Amniocentesis is also covered for non-genetic reasons such as assessing fetal lung maturity, evaluating for infection, and evaluating neural tube defects.⁶ One carve-out: invasive prenatal testing for a variant of uncertain significance (VUS) is classified as experimental and is not covered.

Genetic Counseling

Aetna considers genetic counseling medically necessary across a wide range of pregnancy scenarios: maternal age 35 or older at delivery, abnormal results on ultrasound or serum markers, a prior child with a genetic disorder or birth defect, known or suspected carrier status for autosomal recessive or X-linked conditions, exposure to potentially harmful agents during pregnancy, repeated miscarriages or unexplained stillbirth, ethnic backgrounds at increased risk for specific conditions, and consanguinity.⁷

One caveat matters. Aetna’s policy states that genetic counseling for pregnancy management “may not be covered under plans that exclude family planning benefits.”⁷ If there’s any question about whether family planning is an excluded benefit on your plan, check your plan documents.

Preimplantation Genetic Testing With IVF

If you’re going through IVF and have an advanced reproductive technology benefit, Aetna’s rules split by test type. PGT-M, which tests embryos for a known monogenic disorder the couple carries, is covered when Aetna’s medical necessity criteria are met. PGT-SR is covered when one partner is a known carrier of a balanced translocation or inversion. PGT-A, the broader aneuploidy screening of embryos, is classified as experimental and is not covered — including when it’s being used to optimize IVF outcomes, after failed cycles, or for recurrent miscarriages.⁶

What You’ll Pay and Whether You Need Prior Authorization

Aetna’s 2025 precertification list does not require prior authorization for NIPT, amniocentesis, or carrier screening. Prior authorization is required for whole exome sequencing, whole genome sequencing, infertility services, and preimplantation genetic testing.⁸ Some employer-specific Aetna plans add their own requirements. One employer’s Aetna maternity benefits flyer, for example, says prior authorization is required for genetic testing on that plan, with the in-network provider handling the paperwork.⁹

Costs depend on your plan. Prenatal genetic tests are generally classified as diagnostic rather than preventive, which means they go through your deductible and coinsurance instead of being zero cost. As one example, an Aetna Choice POS II plan charges 20% coinsurance for in-network diagnostic tests after the deductible is met.¹⁰ For your own numbers, check your Summary of Benefits and Coverage or call the member services number on your ID card.

What Aetna Does Not Cover

Several categories of prenatal genetic testing are classified by Aetna as experimental or unproven and therefore excluded:

Expanded NIPT panels covering microdeletions, microduplications, or rare autosomal trisomies beyond chromosomes 13, 18, 21, X, and Y.¹
Single- and multi-gene prenatal cfDNA screens such as PreSeek and Vistara.¹
Repeat carrier screening with the same panel.⁴
Population-based Fragile X screening without a relevant family history or clinical indication.⁴
PGT-A preimplantation aneuploidy screening, for any indication.⁶
Invasive prenatal testing for a variant of uncertain significance.⁶
Noninvasive prenatal diagnosis of sickle cell disease using cell-free fetal DNA.⁴

How to Appeal a Denied Claim

If Aetna denies coverage for a prenatal genetic test you believe should be covered, you have the right to appeal. You have 180 days from the date you receive the denial notice to file your first appeal, and if your plan has a second level, you have 60 days from the first-level decision to file that one.¹¹

A strong appeal includes your clinical records, a letter of medical necessity from your physician, and the medical society guidelines that support the test, such as ACOG’s recommendation that NIPT be offered to all pregnant patients. Ask your provider to quote the relevant Aetna Clinical Policy Bulletin and show point-by-point how your situation meets its criteria. ACOG also publishes a denial appeal letter template specifically for NIPT denials, with pre-written language citing the recommendation that prenatal genetic screening be offered to all pregnant women regardless of age or risk.¹²

If a delay in the decision could jeopardize your health or the clinical decision-making, you can request an expedited appeal. A decision is then due within 72 hours for one-level plans or 36 hours for two-level plans. If internal appeals are exhausted and the denial stands, the Affordable Care Act entitles you to an external review by an independent third party.¹¹

Aetna’s clinical policy bulletins change as the evidence does. If a specific test matters to your care, have your provider verify coverage against the current policy before the test is ordered, and get the authorization — if one is required — in writing.
