Creates provisions relating to perinatal care

HB 470 requires health care professionals providing maternity care to screen all pregnant patients for mental disorders and mental illnesses using a validated, evidence-based tool at the first prenatal visit and throughout all trimesters. The bill mandates that providers either offer treatment or refer patients to treatment if screening identifies untreated mental health needs. The Department of Health and Senior Services must create and publish guidelines for treating these conditions during pregnancy. This directly affects pregnant individuals receiving maternity care and sets new screening protocols for providers, while maintaining confidentiality under existing state and federal laws.
