The Screening Mandate Wave: States Require Perinatal Mental Health Assessment
- California mandated at least one maternal mental health screening during pregnancy and one within 6 weeks postpartum (effective January 1, 2025) — the most comprehensive state-level mandate to date
- Oklahoma SB 1058 requires any provider serving perinatal patients to conduct mental health screenings during healthcare visits — expanding the mandate beyond OB-GYNs
- South Carolina and New Hampshire introduced parallel legislation in 2025, with NH's "Momnibus 2.0" requiring maternal depression screening for all new mothers
- The federal Momnibus Act was reintroduced in March 2026, proposing national standards for maternal mental health care, workforce expansion, and research funding
For decades, perinatal mental health screening has been recommended. Now it is being required. The shift from guidelines to mandates is happening state by state, and the pace accelerated sharply in 2025. For clinicians, this changes the question from "should we screen?" to "how do we screen well — and what happens after a positive result?"
The California model
California's mandate is the most prescriptive. Providers must screen at least once during pregnancy and once within six weeks postpartum. The implementation question — already being studied in a mixed-methods analysis published in Health Affairs Scholar — is whether the infrastructure can absorb the mandate. Screening without a referral pathway is a liability, not a service. California is learning that mandating the question is easy; mandating the answer is harder.
Beyond OB-GYN: Oklahoma's expansion
Oklahoma's SB 1058 is notable for its scope: it requires any healthcare provider serving perinatal patients to conduct mental health screenings. That includes primary care, pediatrics, and emergency departments — not just obstetrics. This reflects growing recognition that perinatal depression and anxiety are identified (and missed) across the healthcare system, not just in the OB-GYN office.
The federal horizon
The Momnibus Act, reintroduced in March 2026, would establish national standards: expanded Medicaid coverage for maternal mental health, workforce training requirements, data collection on perinatal outcomes, and direct funding for community-based organizations. Whether it passes is uncertain, but its reintroduction signals bipartisan recognition that maternal mental health is a systemic problem requiring systemic policy.
For your practice
If you work in perinatal settings or see new parents in any capacity: know your state's mandate status. California, Oklahoma, South Carolina, and New Hampshire already have legislation passed or pending. The screening tools are standardized (EPDS, PHQ-9), but the implementation details — who screens, when, and what referral pathway is activated — are where mandates succeed or fail. Build your referral network now. A positive screen without a warm handoff is worse than no screen at all.
Mandating the screening question is easy. Mandating what happens after a positive answer is the real policy challenge.
State mandates vary in specificity and enforcement mechanisms. Workforce capacity to absorb increased referrals is a significant concern, particularly in rural areas. Federal legislation (Momnibus) has not yet passed. Screening mandate effectiveness data is still being collected.
