This bill, titled the "Healthy Moms and Babies Act," seeks to significantly improve maternal health coverage and outcomes for individuals covered by Medicaid and the Children's Health Insurance Program (CHIP). It introduces mandatory reporting requirements for State Medicaid programs on adult health care quality measures related to maternal and perinatal health, ensuring greater transparency and accountability. A key provision establishes a State option for providing coordinated care through a maternity health home for pregnant and postpartum women, covering services for up to 365 days after pregnancy. These health homes would coordinate comprehensive care, including medical, behavioral health, and social support services, with states receiving planning grants and establishing payment methodologies. The legislation also focuses on reducing cesarean section rates by requiring states to report on low-risk cesarean deliveries and implement quality improvement initiatives. It mandates Medicare reporting on NTSV C-section rates and establishes a program to support perinatal quality collaboratives in reducing C-sections and increasing vaginal births after cesarean (VBACs). To bolster the maternal care workforce, the bill calls for a national expert group to evaluate birthing practices and recommend improvements to education and curricula, including the integration of midwives and doulas. The Medicaid and CHIP Payment and Access Commission (MACPAC) will study doula and community health worker services under Medicaid, followed by guidance from the Secretary on increasing access to these vital supports. Further innovations include demonstration projects to expand the use of telehealth for maternal health services in Medicaid, particularly for underserved populations, and a CMS report on coverage of remote physiologic monitoring devices. The Secretary will also issue guidance on community-based maternal health programs, such as group prenatal care and home visiting services. A critical component addresses maternal mortality and severe morbidity by requiring the Secretary to publish guidance for maternal care providers on reduction strategies. This guidance, informed by a new National Advisory Committee on Reducing Maternal Deaths, will cover best practices for screening, risk identification, educational materials, and clinician checklists. Recognizing the impact of broader factors, the bill mandates reports and guidance on how Medicaid and CHIP data systems can capture information related to social determinants of health (SDOH) . States will be required to collect standardized SDOH information, and the Secretary will provide guidance and facilitate learning collaboratives to help states address these factors for pregnant and postpartum women. Finally, the bill includes provisions for a report on Medicaid payment methodologies for transferring pregnant women between facilities and strengthens program integrity through biennial Payment Error Rate Measurement (PERM) audits for State Medicaid programs, requiring error rate reduction plans for states exceeding a 15 percent threshold.
