HELP Copays Act

Maddy summaryHR 6423, the HELP Copays Act, requires health insurance plans and coverage to count financial assistance from non-profits or drug manufacturers toward patient cost-sharing limits like deductibles and copayments. This directly affects patients enrolled in health insurance who receive such assistance for prescription drugs, ensuring the help they get reduces their out-of-pocket costs faster. The bill amends key health laws to mandate that these payments are included when calculating whether a patient has met their deductible or copayment threshold. The change applies to all prescription drugs, including specialty drugs and those subject to prior authorization, but does not alter how insurers manage drug access through tools like step therapy. It takes effect for plan years starting in 2026.

Dignity for Detained Immigrants Act

Maddy summaryThe Dignity for Detained Immigrants Act establishes minimum standards for detention facilities operated by the Department of Homeland Security, requiring them to follow the American Bar Association's Civil Immigration Detention Standards. It mandates annual unannounced inspections by the DHS Inspector General, with penalties including fines for noncompliant private facilities and transfers of detainees from noncompliant facilities. The bill requires DHS to publicly report on facility compliance, phase out private detention facilities over three years, and prohibit solitary confinement. It also ensures detainees have access to legal orientation, counsel, and more frequent custody review hearings. The bill directly affects all individuals detained in DHS custody, including immigrants, asylum seekers, and refugees held in facilities operated by or contracted to DHS.

Mikaela Naylon Give Kids a Chance Act

Give Kids a Chance Act of 2025 This bill expands the Food and Drug Administration’s (FDA’s) authority with respect to research on rare pediatric diseases, including by permitting the FDA to take enforcement action against drug sponsors that fail to satisfy pediatric study requirements and by reauthorizing programs that support pediatric research.  Specifically, the bill modifies requirements relating to molecularly targeted pediatric cancer investigations to permit research on new drugs in combination with active ingredients that have already been approved, provided certain conditions are met; permits the FDA to take enforcement action against drug sponsors that fail to comply with pediatric study requirements, if such sponsors demonstrated a lack of due diligence in satisfying the requirement; renews the FDA’s authority to award priority review vouchers to sponsors of new products intended to treat rare pediatric diseases through September 30, 2029; and reauthorizes through FY2027 certain funding for the National Institutes of Health to support priority pediatric research.  The bill also provides statutory authority for the FDA’s interpretation of the orphan drug exclusivity period. The bill specifies, consistent with FDA regulations, that the seven-year market exclusivity period for drugs for rare diseases or conditions (i.e., orphan drugs) prohibits the approval of the same drug for the same approved use or indication with respect to the disease or condition. (In Catalyst Pharmaceuticals, Inc. v. Becerra , a court rejected the FDA’s interpretation and held that orphan drug exclusivity extends to all uses or indications for the disease or condition.)

International Maritime Pollution Accountability Act of 2025

Maddy summaryThis bill establishes fees on carbon emissions and air pollutants from maritime shipping, with reporting requirements starting in 2027. Ship operators must report detailed voyage data including fuel consumption, ports visited, and cargo details, while importers of cargo bound for the U.S. face similar reporting and fee obligations. Revenue from these fees funds specific decarbonization programs: 25% supports modernizing Jones Act vessels, 25% funds low-carbon fuel research, 10% each goes to harbor craft and ferry electrification, and 5% each supports workforce development and air monitoring in port communities. The bill creates a structured funding mechanism to reduce emissions from shipping while requiring transparency through comprehensive reporting.

CARE for Moms Act

Maddy summaryThe CARE for Moms Act aims to reduce maternal mortality in the United States by expanding access to comprehensive care for pregnant and postpartum individuals. It directly affects women, particularly Black women who face disproportionately higher maternal mortality rates, as well as rural and underserved communities. Key provisions include funding State-based perinatal quality collaboratives ($35 million annually), requiring 12-month Medicaid coverage for postpartum individuals, mandating oral health services during pregnancy, supporting doula services through $50 million in grants, and creating regional centers to address implicit bias in healthcare. The bill also establishes rural mobile health units for obstetric care and requires hospitals to notify authorities 90 days before closing obstetric units. These changes aim to address systemic issues contributing to the U.S. maternal mortality crisis, which has the highest rate among developed nations.

Lowering Drug Costs for American Families Act

Maddy summaryThis bill expands Medicare's drug price negotiation program to cover 50 drugs (up from 20) and requires health insurers to apply negotiated prices to cost-sharing for beneficiaries. It establishes annual out-of-pocket cost-sharing limits for prescription drugs under group health plans and insurance coverage, with specific limits of $2,000 for self-only coverage in 2027 that will increase annually. The bill also sets specific cost-sharing limits for insulin products, requiring coverage with no deductible and cost-sharing of no more than $35 per 30-day supply or 25% of the negotiated price. These provisions affect Medicare beneficiaries, people with group health plans, and health insurers across the country. The bill applies to plan years beginning on or after January 1, 2027.

John Lewis Every Child Deserves a Family Act

Maddy summaryHR 6181, the John Lewis Every Child Deserves a Family Act, prohibits child welfare agencies receiving federal funds from discriminating against children, youth, or prospective foster/adoptive parents based on religion, sex (including sexual orientation and gender identity), or marital status. It directly affects LGBTQ youth in foster care - overrepresented at 30% of the system - who face higher risks of trauma, group home placements, and suicide attempts compared to non-LGBTQ peers. Key provisions require agencies to collect data on sexual orientation and gender identity, establish a National Resource Center for LGBTQ youth support, provide cultural competency training, and eliminate discriminatory practices. The law aims to improve safety, permanency, and placement stability by expanding access to family-based care and ensuring equitable services for all children in the system.
