Co-sponsor SB 2370
Signed into law · North Dakota Senate · Co-sponsor
AN ACT to provide for a legislative management study regarding prescription drug transparency reporting under the federal drug discount program.

Maddy summarySB 2370 sets a $25 maximum out-of-pocket cost for a 30-day supply of insulin drugs and related medical supplies (like test strips, syringes, and glucose meters) under most North Dakota health insurance plans. It directly affects residents with diabetes who rely on insulin coverage through private insurance, requiring plans to cap costs at $25 for both insulin medications and essential supplies. The bill prohibits insurers from imposing deductibles, copayments, or other cost-sharing that exceeds these limits, while excluding Medicare Part D plans and devices like insulin pumps. It amends existing insurance coverage laws to enforce these caps, with the law set to expire on July 31, 2025.

The resolution does not create new laws but requests a formal study to inform future education, prevention, and policy efforts. It was passed unanimously (93-1) and signed by leadership in April 2025.

Counties receiving grants must contribute at least 25% of project costs, and at least 25% of annual funds must support projects in counties with populations under 15,000.

Co-sponsor HB 1603
Signed into law · North Dakota House · Co-sponsor
AN ACT to provide an appropriation to the state historical society for Native American grave protection and repatriation compliance efforts.

Maddy summaryHB 1603 appropriates $500,000 from North Dakota's general fund to the state historical society for compliance with the federal Native American Graves Protection and Repatriation Act (NAGPRA). The funds establish a committee with tribal historic preservation officers, state agencies, and the attorney general's office to prioritize returning human remains, sacred objects, and culturally significant items to North Dakota tribes. Tribes must contribute up to $100,000 in matching funds for committee efforts, and all funds must be tracked separately. The bill explicitly prohibits using these funds for new scientific studies of ancestral remains. This law directly affects North Dakota tribes and the state historical society by enabling repatriation efforts under federal law.

Co-sponsor HB 1205
Signed into law · North Dakota House · Co-sponsor
AN ACT to amend and reenact section 50-25.1-15 of the North Dakota Century Code, relating to abandonment of infants in newborn safety devices.

Maddy summaryHB 1205 allows parents or their agents to anonymously leave infants under 60 days old in secure, 24/7 monitored safety devices at designated hospitals or leave them with on-duty staff at approved locations without facing prosecution under certain criminal codes. The bill defines "newborn safety devices" as temperature-controlled, alarm-equipped units visible to staff, and requires hospitals to accept infants without asking for parent information or medical history. It also creates a numbered identification bracelet system to link parents to infants for potential reunification, while guaranteeing confidentiality of parent identities unless the infant was harmed. The law provides immunity to hospitals and staff for accepting infants under these provisions and mandates a public awareness campaign about the program.
