The levels of maternal care are a national framework for matching pregnant patients to facilities equipped to handle their level of risk. Established by ACOG and SMFM, the levels of maternal care designation runs from Level I through Level IV, with each level describing the capabilities, staffing, and resources a birth facility maintains. The goal is straightforward: make sure a patient with a high-risk pregnancy delivers where the right expertise and equipment are available, and avoid concentrating low-risk births in the highest-resource centers. This article explains what each maternal levels of care designation means and why the framework matters.
Why do levels of maternal care exist?
The framework exists because outcomes improve when risk and resources are matched. ACOG and SMFM introduced uniform levels of maternal care to reduce maternal morbidity and mortality by ensuring that patients with serious conditions deliver at facilities capable of managing them. This concept is called risk-appropriate care.
The idea parallels how trauma systems and neonatal care are organized. For decades, neonatal intensive care has used NICU levels to define which facilities can care for the sickest newborns. Maternal levels of care extend that same logic to the pregnant patient, who historically received less systematic attention than the baby. Because maternal and neonatal risk often travel together, the two frameworks are designed to complement each other, though a facility's maternal level and its NICU level are assessed separately and do not always match.
What does each maternal levels of care designation mean?
Here is what the ACOG and SMFM framework describes at each level. Capabilities build cumulatively, so each higher level includes what the levels below it provide.
Birth center. Accredited freestanding birth centers care for low-risk patients with uncomplicated, term pregnancies, typically staffed by midwives, with plans in place for transfer if complications arise.
Level I, basic care. These facilities provide care for uncomplicated pregnancies and have the ability to detect, stabilize, and manage or transfer unexpected complications. They can perform cesarean delivery.
Level II, specialty care. In addition to basic care, Level II facilities manage certain higher-risk conditions and have obstetric and, typically, some subspecialty support available.
Level III, subspecialty care. These facilities manage more complex maternal and fetal conditions, with maternal-fetal medicine (MFM) specialists, advanced imaging, and the ability to care for serious complications available on site.
Level IV, regional perinatal health centers. The highest designation, Level IV centers care for the most complex and critical maternal conditions, with on-site MFM, maternal intensive care, and a broad range of medical and surgical subspecialties. They also serve as regional resources, providing consultation, transport coordination, and outreach to lower-level facilities.
How do levels of maternal care relate to NICU levels?
The two systems are parallel but separate. NICU levels, defined by the American Academy of Pediatrics, describe a facility's capacity to care for newborns, from Level I well-newborn nurseries through Level IV regional NICUs. Maternal levels of care describe the facility's capacity to care for the mother.
A facility is assigned each designation independently, because a pregnancy can be high risk for the parent, the baby, or both. Ideally a facility's maternal and neonatal capabilities are aligned, but planners look at both when deciding where a particular patient should deliver. For a patient whose baby is expected to need intensive neonatal care, the delivering facility's NICU level matters as much as its maternal level.
Where do AIM safety bundles fit in?
Levels of maternal care define where care happens. AIM safety bundles help define how it happens. The Alliance for Innovation on Maternal Health (AIM), supported by federal funding and aligned with ACOG and SMFM, develops patient safety bundles: structured sets of evidence-based practices that facilities implement to respond consistently to specific emergencies, such as obstetric hemorrhage and severe hypertension in pregnancy.
The two work together. A well-designed maternal care system places patients at the right level and equips every level with standardized safety bundles so that when an emergency occurs, the response is fast and consistent regardless of where the patient is. Together they form the backbone of risk-appropriate care.
Why does this matter for patients and health systems?
For patients, the framework is the reason a woman with a serious condition may be advised to deliver at a Level III or IV center rather than her local hospital. It is not bureaucratic. It is the difference between having MFM and critical-care resources immediately available or not. For a fuller picture of what elevates a pregnancy's risk, see our high-risk pregnancy guide.
For health systems, the levels create both a responsibility and an opportunity. Lower-level facilities need reliable pathways to consult with and transfer to higher-level centers, and higher-level centers need to extend their expertise outward. This is where telehealth increasingly plays a role, letting MFM specialists at regional centers support lower-level and rural facilities without every patient traveling.
Ouma Health is a real medical practice, not an app, founded by MFM specialists and built to extend that subspecialty expertise across facilities and geographies. That kind of virtual specialist support helps lower-level and rural sites deliver more risk-appropriate care locally. Learn more on our pages for hospitals and high-risk pregnancy.
Frequently asked questions
What are the levels of maternal care?
They are a national framework from ACOG and SMFM that classifies birth facilities by capability, from accredited birth centers and Level I basic care up to Level IV regional perinatal health centers, so patients can deliver where their risk level can be managed.
How are levels of maternal care different from NICU levels?
Maternal levels describe a facility's ability to care for the pregnant patient, while NICU levels describe its ability to care for newborns. They are assigned separately because a pregnancy can be high risk for the parent, the baby, or both.
What is risk-appropriate care?
It is the principle behind the framework: matching each patient to a facility with the right resources for her level of risk, so low-risk births are not concentrated in the highest-resource centers and high-risk patients get specialist care.
What are AIM safety bundles?
Developed by the Alliance for Innovation on Maternal Health, they are structured sets of evidence-based practices that facilities adopt to respond consistently to obstetric emergencies such as hemorrhage and severe hypertension, complementing the levels of maternal care.
