GROUP PRENATAL CARE
WHAT IS GROUP PRENATAL CARE AND WHY IS IT IMPORTANT?
Group prenatal care is a model of prenatal care facilitated by a trained healthcare provider, and delivered in a group setting, which integrates health assessments, education and skills building, and peer social support.1,2 Group prenatal care typically serves 8 to 12 expectant parents of similar gestational age who meet every 2 to 4 weeks, totaling 15 to 20 hours in prenatal care over the course of their pregnancies, compared to 2 to 4 hours in traditional individual care.3,4,5
Early and Regular Prenatal Care Improves the Likelihood of a Healthy Pregnancy
The American College of Obstetricians and Gynecologists and the American Academy of Pediatrics recommend evaluating the needs and risks of expectant parents early and continuously throughout prenatal care.6 Research shows that pregnant individuals who receive adequate care early in pregnancy experience positive perinatal outcomes through the education, risk screening, and physical assessments included in prenatal care visits.7,8
Group Prenatal Care Adds Social Support to Traditional Prenatal Care
Group prenatal care augments the individual prenatal care model in ways that can positively impact expectant parents and their families by integrating family members and peer support into prenatal care and education, which can be a protective factor for an expectant parent’s psychosocial health. Further, group prenatal care includes more contact with providers and medical support services, which may better serve the needs of participants.9
Expectant Parents May Be More Likely to Attend Group Prenatal Care Visits Compared to Traditional Prenatal Care
Group prenatal care emerged as an alternative form of care, in part as a response to challenges with accessing individual prenatal care.10 Group prenatal care provides expectant parents with more time with providers and is intended to improve the relationship between providers and patients. Expectant parents who choose group prenatal care over individual care may be more likely to attend more of their scheduled visits if group prenatal care meets their needs in ways that individual care does not.
CenteringPregnancy Is the Most Prominent Model of Group Prenatal Care
CenteringPregnancy is the most widely studied model and the model on which other forms of group prenatal care are often based.11 CenteringPregnancy is currently being implemented in approximately 386 sites across 41 states.12
Other group prenatal care programs were examined for the Roadmap, but no additional programs had evaluations that met our criteria for strong causal studies. Studies of Expect With Me and the March of Dimes Supportive Pregnancy Care program found beneficial and mixed results for families, respectively. However, studies of both programs did not meet our strong causal study criteria. Other less rigorously studied group prenatal care programs include Pregnancy & Parenting Partners and Honey Child.

WHAT IMPACT DOES GROUP PRENATAL CARE HAVE AND FOR WHOM?
Participation in group prenatal care improves the likelihood that mothers receive adequate prenatal care. Impacts on mothers’ physical and emotional health and on breastfeeding initiation have been found to be both positive and null. The most rigorous studies on healthy and equitable births typically find no differences between group and traditional prenatal care, suggesting that group prenatal care can be a safe alternative to traditional care.
More Research Is Needed to Determine the Potential of Group Prenatal Care to Decrease Racial and Ethnic Disparities
Systemic racism, combined with discrimination within hospital and health care delivery systems, is one of the drivers of poorer quality prenatal care and adverse birth outcomes among people of color.13 Some existing evidence indicates that group prenatal care benefits Black mothers—Black mothers participating in group prenatal care were significantly less likely to receive inadequate prenatal care or have a preterm birth compared to Black mothers who did not participate in group prenatal care.14,15 These results, however, are not sufficient to conclude that group prenatal care addresses racial disparities in prenatal care or birth outcomes. Future research should focus on examining the differential impacts of group prenatal care by race and ethnicity.

WHAT ARE THE KEY POLICY LEVERS TO INCREASE ACCESS TO GROUP PRENATAL CARE?
The current evidence base does not clearly identify a specific policy lever that states should adopt and implement to ensure access to group prenatal care services for expectant parents who want this type of care.
We identified two key policy levers that states can implement to increase access to group prenatal care services in their state:
- Offer an enhanced Medicaid reimbursement rate to incentivize group prenatal care, and
- Invest funding to pilot or scale up group prenatal care in the state.
As of September 2026, 11 states offer an enhanced Medicaid reimbursement rate to incentivize group prenatal care, and five states invest funding to pilot or scale up group prenatal care. In total, three states have implemented both key policy levers to improve access to group prenatal care.
Key Policy Lever: Offer an Enhanced Medicaid Reimbursement Rate to Incentivize Group Prenatal Care
States can implement Medicaid billing codes that reimburse providers for group prenatal care at a rate that is higher than traditional prenatal care. Enhanced reimbursement rates incentivize providers to offer group prenatal care and more accurately reflect the additional time and costs associated with providing group prenatal care. Enhanced reimbursement rates vary considerably, with some states offering an additional $40 to $50 per patient, per visit for group prenatal care, and other states offering a rate that only provides additional funding to providers if they serve large groups.
CenteringPregnancy has worked with many states to create billing codes within state Medicaid programs and the organization recommends that states reimburse providers at least an additional $45 per patient, per visit. Some states require that group prenatal care models are certified CenteringPregnancy programs to be reimbursable, but other states are not specific as to which group prenatal care model can receive enhanced reimbursements.
As of September 2026, 11 states offer an enhanced Medicaid reimbursement rate to incentivize group prenatal care. Previously, state MCOs in Georgia and Louisiana offered enhanced Medicaid reimbursement rates for group prenatal care, but the rates were not available this year.
Despite having billing codes and enhanced reimbursements, some states experience low take-up of the billing codes for various reasons, including lack of education about the services/codes and/or low reimbursement rates. For example, Montana offers enhanced reimbursement rates for group prenatal care, but in 2026 they did not have any CenteringPregnancy sites, which may indicate that the billing codes are not being used.
Key Policy Lever: Invest Funding to Pilot or Scale Up Group Prenatal Care
States may also invest funds to pilot initiatives that reimburse group prenatal care services at a rate that is higher than traditional prenatal care or to scale up a group prenatal care model in the state. In the last year, three states (Kansas, Utah, and Virginia) began providing grants to expand access to group prenatal care services or using discretionary funding to pilot initiatives that reimburse providers at an enhanced rate. Michigan and Texas continued providing funding for similar initiatives. The Maryland Department of Health previously provided grant funding to expand CenteringPregnancy sites in the state beginning in 2023, but the grant cycle ended in 2026. Although Kansas has invested to expand group prenatal care, the state does not yet have an active CenteringPregnancy site.
States Also Support Group Prenatal Care Through Nonfinancial Initiatives
States have also taken steps to encourage group prenatal care by recognizing it as an effective strategy for improving maternal and child health outcomes and/or by listing CenteringPregnancy as a resource on state websites. Of the 13 states that recognize group prenatal care as an effective strategy, three states (Montana, New Jersey, and North Carolina) also provide support through enhanced reimbursements or grant funding to support pilot programs. Two states (Wisconsin and Wyoming) recognize group prenatal care as an effective strategy but do not have any CenteringPregnancy sites.

HOW DOES ACCESS TO GROUP PRENATAL CARE VARY ACROSS STATES?
Group prenatal care can be offered by health providers using their own method or other models, however, national data on the number of group prenatal care sites in a state are only available for the CenteringPregnancy model, which is the only model with a rigorous evidence base, to date.
Based on the most recent data from 2026, 41 states offered at least one CenteringPregnancy site. Ten states (Alaska, Delaware, Idaho, Kansas, Mississippi, Montana, South Dakota, Vermont, Wisconsin, and Wyoming) had no CenteringPregnancy sites in 2026.
Of the 41 states that have at least one CenteringPregnancy site, 14 states have only one single site. In comparison, California and Michigan have the greatest number of sites—55 and 40, respectively. Michigan has continued to add sites after implementing an enhanced Medicaid reimbursement rate and investing state funds in group prenatal care in 2024.
The number of CenteringPregnancy sites available in states is an important metric, however, data on the number of families served at each site are unavailable, which makes it difficult to assess the full reach of sites. Additionally, the availability of an enhanced Medicaid reimbursement rate is not necessarily correlated with the number of sites per state. Some states with more generous rates have a lower number of sites, and some states with less generous rates have a higher number of sites.
WHAT PROGRESS HAVE STATES MADE IN THE LAST YEAR TO INCREASE ACCESS TO GROUP PRENATAL CARE SERVICES?
In the last year, two state managed care organizations (MCOs) removed their existing enhanced reimbursement rates for group prenatal care. Previously, CareSource in Georgia offered an enhanced reimbursement of $30 per patient, per visit and HealthyBlue LA in Louisiana offered $50 per patient, per visit. This year, these MCOs did not include group prenatal care or CenteringPregnancy in their provider manuals.
Three states (Kansas, Utah, and Virginia) began providing state or payor grants to CenteringPregnancy sites to expand access to group prenatal care in 2026. Previously, the Maryland Department of Health provided a 3-year grant to expand CenteringPregnancy sites in the state in 2023, the grant cycle ended this year.
In the last year, lawmakers in Michigan introduced legislation that would codify Medicaid reimbursement for group prenatal care and require all insurers in the state to cover and reimburse for group prenatal care. As of September 2026, the bills had not passed.
Additionally, two states (Alabama and Mississippi) introduced, but did not ultimately pass, comprehensive maternal health bills in the last year that included measures to expand group prenatal care. Alabama lawmakers introduced the Rural Maternal and Infant Health Equity Act which would have included funding for local maternal health partnerships providing group prenatal care and other services. Mississippi lawmakers introduced the Maternal Health Momnibus Act, which would have directed the Department of Health to provide group prenatal and postpartum care either in-person or virtually beginning in July 2027. The program would have been available for women who qualify for Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and would have provided five prenatal and five postpartum visits free of charge.
Federal Changes to Medicaid May Impact State Medicaid Offerings
In 2025, the federal government passed the One Big Beautiful Bill Act (OBBBA), making cuts to federal funding for Medicaid.16 These funding cuts may impact coverage of evidence-based programs such as group prenatal care and may cause states to remove benefits such as enhanced reimbursement rates. Though it is not clear whether these actions are directly tied to federal changes to Medicaid, California eliminated an enhanced reimbursement rate for group prenatal care in 2025 and managed care organizations (MCOs) in Georgia and Louisiana eliminated previously offered enhanced reimbursement rates in the last year.
Work to understand the implications of federal policy changes on state budgets is ongoing, though changes are anticipated to have a detrimental effect on state support for evidence-based policies and strategies such as group prenatal care.
