Prenatal appointment schedule in the US

What the schedule looks like

There is no national prenatal appointment schedule in the United States in the way there is in the UK. What exists is a long-standing convention, largely unchanged for decades, that your obstetric provider adapts to you. The Office on Women's Health sets it out as:

• About once a month for weeks 4 through 28
• Twice a month for weeks 28 through 36
• Weekly from week 36 until birth

Followed from a first-trimester start, that adds up to roughly 12 to 14 visits across a term pregnancy — noticeably more than the 7 to 10 offered in the UK. If you are over 35 or your pregnancy is higher risk because of conditions such as diabetes or high blood pressure, expect to be seen more often.

When to start

ACOG says it is best to start prenatal care in the first trimester, and that before 10 weeks after your last period is ideal. In practice the timing depends on when you find out, how quickly you can get an appointment, and your insurance situation.

Call to book as soon as you have a positive test. Practices in many areas book out weeks ahead, and several early tests — carrier screening, cell-free DNA from 10 weeks, first-trimester screening between 10 and 13 weeks — have windows that close.

Tailored prenatal care and telehealth

ACOG now uses the term “tailored prenatal care” for a plan built around your specific risk rather than a fixed calendar. The COVID-19 pandemic accelerated this: obstetrician-gynecologists began separating visits that need a physical exam or lab draw from those that are essentially counseling, and moving the latter to telehealth.

ACOG's guidance is that for average-risk pregnancies you may need only periodic in-person visits as long as no complications develop, and that you and your ob-gyn should agree how often you come in. Some practices also offer group prenatal care, where you meet in a cohort of other pregnant patients for longer sessions.

This is worth raising explicitly, because it can cut travel, childcare and time off work substantially. Ask which visits can be virtual and which cannot.

Who provides your care

Several types of clinician provide prenatal care in the US, and the choice affects cost, location and birth options:

• Obstetrician-gynecologists (ob-gyns) are physicians specializing in women's health. Most people get prenatal care from an ob-gyn.
• Maternal-fetal medicine (MFM) specialists are ob-gyns with extra training in high-risk pregnancy. You may be referred to one if complications develop.
• Family medicine physicians provide prenatal care for average-risk pregnancies, and may hand over to an ob-gyn if complications arise.
• Certified nurse-midwives provide care for low-risk pregnancies, often within an ob-gyn practice or a hospital system.

Confirm before your first visit that the practice is in-network and that the hospital they deliver at is also in-network. These are billed separately in the US and being in-network for one does not mean being in-network for the other.

What happens at visits

The first visit is the longest. Expect a full health history covering past illnesses, surgeries and prior pregnancies, a physical exam, a pelvic exam, dating of the pregnancy, and a substantial round of blood and urine work.

Later visits are short and follow a pattern: weight, blood pressure, urine dipstick, fundal height measurement, fetal heart rate, and questions about movement, symptoms and mood. Specific things attach to specific visits:

• First visit: blood type and Rh factor, complete blood count, urinalysis and urine culture, hepatitis B, hepatitis C, HIV, syphilis, and screening for chlamydia and gonorrhea.
• 10 weeks onward: cell-free DNA screening becomes available.
• 10 to 13 weeks: first-trimester screening (blood test plus nuchal translucency ultrasound).
• Around 18 to 22 weeks: the detailed anatomy ultrasound.
• 24 to 28 weeks: glucose screening for gestational diabetes, and Rh immune globulin if you are Rh negative.
• 27 to 36 weeks: Tdap vaccination, recommended in every pregnancy.
• Third trimester: repeat syphilis test — ACOG recommends testing three times in total, at the first visit, in the third trimester and at delivery.
• 36 to 38 weeks: group B streptococcus culture, a vaginal and rectal swab.

Cost, coverage and what to do if you are uninsured

This is the part with no UK equivalent. Under the Affordable Care Act, most plans must cover certain preventive services without cost-sharing, but prenatal visits, ultrasounds, screening tests and delivery are generally subject to deductibles, copays and coinsurance. Ask your plan for the maternity benefit summary in writing and ask the practice for a global maternity fee estimate, which typically bundles routine prenatal visits and delivery but excludes labs, ultrasounds and anesthesia.

If you are uninsured, pregnancy is a qualifying life event that opens a special enrollment period on the Health Insurance Marketplace, and birth of a child is too. Medicaid covers pregnancy at higher income thresholds than for other adults in most states, and eligibility is assessed by household size counting the unborn child. Federally Qualified Health Centers provide prenatal care on a sliding scale regardless of insurance or immigration status. None of these routes requires you to delay your first visit while you sort out coverage — book, then sort it out.

Where to get help

The American College of Obstetricians and Gynecologists is the governing professional authority for prenatal care standards in the US, and its patient FAQs describe what routine care should look like. The Office on Women's Health publishes the visit schedule in plain language. For coverage questions, HealthCare.gov handles Marketplace enrollment and your state Medicaid agency handles pregnancy Medicaid.
