An explainer
One year of preterm births in the United States carries a lifetime cost of about $24 billion, counted over those children's lives, in 2016 dollars. That's 373,986 births times $64,815, the published average cost per preterm birth (Waitzman et al., 2021) validated: the NICU, years of care, special education, lost earnings. Pick your state.
Then look at the timeline. The steps that can move a birth later sit early in pregnancy: aspirin, where it's indicated, is best started before 16 weeks; a short cervix is found at the scan between 18 and 24 weeks and treated from that day; a cerclage goes in before 24. A pregnancy that reaches care late has already passed most of them, and catching them is the system's job, not the mother's. The weeks before care begins are the missing weeks.
Births and the preterm-birth rate come from the national vital-statistics record. We add no model of our own. The $64,815 is a published estimate, and the only arithmetic on this page is multiplication.
$64,815 is the average lifetime cost per preterm birth in 2016 dollars (Waitzman et al., 2021), blended across all severities. Most preterm babies are born at 34–36 weeks and cost relatively little; for a birth before 29 weeks, Medicaid claims put the hospital stay alone at about $223,000 (McLaurin et al., 2019) plausible. It is not an annual figure and it is not inflated. context
For decades, most of a pregnancy's care has been billed as one package. That changes on January 1, 2027.
The American Medical Association's CPT Editorial Panel has deleted the global obstetric package codes, effective January 1, 2027. In their place, prenatal and postpartum visits are reported one at a time as evaluation-and-management visits, including telemedicine and home visits, and labor management and delivery get new codes of their own. validated · AMA text
Our argumentWhen each prenatal visit is its own claim, each visit has its own date. A plan already knows whether care started on time. From January 2027 every visit after that is coded on its own, with its own date.
That cuts both ways, and the people who study maternity payment say so. Unbundling can fragment care and bury small practices in claims (Policy Center for Maternal Mental Health, 2026). It could also do something the bundle hid. Scans and lab tests were always billed on their own; the visits weren't. Unbundled, the visit where aspirin is started and the visit where a short cervix is acted on can be paid as the events they are, and their absence shows. Medicaid finances more than 40% of U.S. births (KFF), so state Medicaid agencies and their plans will decide much of what that visibility is worth.
This site exists to put the arithmetic in front of that decision.
Our argumentInterventions get reviewed on how they fit the current payment system. They should be reviewed on what they're worth.
The reason a cost-saving intervention sits unused is often not the science, in our reading. It is that the party who pays for prevention is usually not the party who banks the savings. A prenatal plan spends the money; the NICU bill, the special-education budget, and the decades of lost earnings land in other pockets, other years, other agencies. So everyone waits for more evidence, or for someone else to go first.
Of what a preterm birth costs over a lifetime, the largest share is medical, about two-thirds (Waitzman et al., 2021) validated, and over 90% of that medical cost is the hospital stay in infancy (same source) validated: one hospital's budget, one year. The returns are spread across decades and across budgets that never see the invoice. Nobody who pays can see what they bought; nobody who saves knows whom to thank. No single budget-holder captures enough of the return to justify going first. That's a ledger problem before it's a medical one.
The missing weeks are the weeks of pregnancy that pass before prenatal care begins. They cost what they cost because of what's scheduled inside them.
Doulas and group prenatal care have real value for engagement and experience of care; neither has been shown in randomized trials to prevent preterm birth, so neither is credited with it here. And one injection that was the standard of care for a decade, 17-OHPC, is on the sources page as de-adopted: its confirmatory trial didn't hold up, and the FDA withdrew it in 2023.
Every figure on this page is a published estimate, graded for how solid it is. The arguments are ours, and they're marked as arguments. The full list, with the grades explained, is on the Sources page.
