Health insurance and maternity cover in the US: what is guaranteed

The one guarantee, and it is a real one

HealthCare.gov states it without qualification: all Marketplace and Medicaid plans cover pregnancy and childbirth. This is true even if your pregnancy begins before your coverage starts.

That second sentence is doing heavy lifting. In a system that once allowed pregnancy to be treated as a pre-existing condition and excluded, the current rule is that maternity care and newborn care, the services provided before and after your child is born, are essential health benefits. Federal regulation lists maternity and newborn care as one of the ten categories every essential health benefits benchmark plan must include.

So the cover is not a feature you shop for. If the plan is a qualified health plan or Medicaid, pregnancy is in it.

The trap: pregnancy is not a qualifying life event

Here is the sentence that costs people the most money, and it is easy to miss. Being pregnant does not qualify you for a Special Enrollment Period, but the birth of a child does.

In plain terms: finding out you are pregnant in March does not, by itself, let you buy a Marketplace plan in March. Open Enrollment runs November 1 to January 15 each year. Outside that window you need a qualifying life event such as moving or losing other coverage.

If you do not qualify for a Special Enrollment Period right now, HealthCare.gov says you will be eligible to apply within 60 days of your child's birth, and can also enrol for the next plan year during the next Open Enrollment Period.

Medicaid and CHIP do not have that window

This is the escape hatch and it is worth checking even if you assume you earn too much. If you are eligible for Medicaid or the Children's Health Insurance Program, your coverage can begin at any time. There is no enrolment season. You apply by starting a Marketplace application and indicating that you want help paying for coverage.

The postpartum coverage cliff

If you are found eligible for Medicaid during your pregnancy, you will be covered for at least 60 days after you give birth, depending on your state. Some states offer coverage for a full 12 months after you give birth.

That difference is enormous for anyone managing postpartum depression, a difficult recovery or a chronic condition, and it is decided entirely at state level. HealthCare.gov tells you to check with your state. We are not going to publish a fifty-state table here and let it go stale, because being wrong about this costs someone their care in month three.

When your state's coverage period ends you may no longer qualify, and your state will notify you. Losing Medicaid or CHIP coverage after giving birth is itself a qualifying event for a Special Enrollment Period, so you can move to a Marketplace plan.

If you already have Marketplace coverage

Two pieces of counter-intuitive official advice. If you want to keep your current Marketplace plan, HealthCare.gov says do not report your pregnancy to the Marketplace. But reporting it may help you and your family get the most affordable coverage, because it can change what you and your household qualify for.

Which is right for you depends on your income and household. Read both options before you update your application, because the change is not always reversible mid-year.

After the baby arrives

Apply within 60 days after your baby's birth. Your plan can cover you, your baby and any other household members. Miss the 60 days and, unless you have another qualifying event, you are waiting for Open Enrollment.

What we cannot tell you

Medicaid income thresholds for pregnant women, postpartum coverage length, whether your state expanded Medicaid, and which providers and facilities are in your plan's network are all state and plan-level facts. There is no single national answer and we are not going to generalise from one state.

Two calls give you your real answer: your state Medicaid agency, and your insurer's member services line. Ask the insurer specifically about the delivery facility and the anaesthesiology and neonatology groups that work in it, because an in-network hospital can still contain out-of-network clinicians.

The ten essential health benefits

It is worth knowing the full list, because several categories matter after the birth as much as during pregnancy. Federal regulation requires every essential health benefits benchmark plan to cover ambulatory patient services, emergency services, hospitalisation, maternity and newborn care, mental health and substance use disorder services including behavioural health treatment, prescription drugs, rehabilitative and habilitative services and devices, laboratory services, preventive and wellness services and chronic disease management, and paediatric services.

Mental health parity and habilitative services are the two most often forgotten. Postnatal depression treatment and paediatric therapy both sit inside that list.

Coverage still begins even if you are already pregnant

The rule that pregnancy cannot be treated as a pre-existing condition is worth restating, because it reverses decades of practice. If you enrol during Open Enrollment while already pregnant, the plan covers the pregnancy and the birth. There is no waiting period to serve and no exclusion to argue about.

Getting the details right

Ask your insurer to confirm in writing that both the delivery facility and your provider are in-network, and ask specifically about the anaesthesiology and neonatology groups working in that facility, because they are often separately contracted. Ask what happens if you deliver outside the plan's service area.
