Pro Codes Act of 2026

Maddy summaryThis bill, known as the Protecting and Enhancing Public Access to Codes Act of 2026, adds a new section to the U.S. Copyright Code to address standards that are incorporated by reference into federal, state, and local laws and regulations. The legislation requires standards development organizations to make these incorporated standards freely available online at no cost to the public, including searchable tables of contents and indexes, while still protecting the organizations' copyright rights. The bill defines key terms such as "incorporated by reference" and "standards development organization" to clarify which materials fall under these requirements. It also establishes that copyright protection for these standards continues even after they are referenced in laws, provided the organization makes them publicly accessible online within a reasonable time of being notified about the incorporation. The measure aims to balance public access to technical standards used in regulations with the ability of standards organizations to fund their work through licensing and sales.

Safe Step Act

Maddy summaryS 2903, the Safe Step Act, requires health insurance plans and employers offering health coverage to establish a clear, timely process for patients or doctors to request exceptions when step therapy protocols (where insurers require trying cheaper drugs first) would harm a patient. It mandates approval for exceptions if prior drugs failed, delay would cause severe harm, a drug is unsafe, or a patient is stable on their current medication. Plans must respond to requests within 72 hours (or 24 hours in emergencies) and cover the requested drug without extra cost-sharing. The bill also requires annual reports to the government on exception requests, approvals, denials, and trends by medical condition or specialty. This directly affects patients on health plans with step therapy, their doctors, and the insurers managing those plans.

Ensuring Lasting Smiles Act

Maddy summaryThis bill (S 1677, Ensuring Lasting Smiles Act) requires health insurance plans to cover medically necessary treatments for congenital anomalies or birth defects affecting the eyes, ears, teeth, mouth, or jaw. It mandates coverage for reconstructive services, dental/orthodontic care, and related treatments during the course of medical treatment, while excluding purely cosmetic procedures not medically necessary. Plans may apply cost-sharing requirements similar to those for other medical services but must provide notice about these coverage requirements to participants by January 1, 2026. The bill also directs a study on provider network adequacy and cost impacts related to these coverage requirements, to be completed by December 2027.

RESPECT Act of 2025

Maddy summaryThis bill amends a provision in the U.S. Code regarding national cemetery interments, specifically changing the legal definition used to determine who is barred from burial. It updates references from "tier III sex offender" under outdated law (34 U.S.C. § 20901) to the current definition (34 U.S.C. § 20911) for the Sex Offender Registration and Notification Act. This change directly affects individuals classified as tier III sex offenders under current law, altering the criteria applied when reviewing burial eligibility in national cemeteries. The bill makes a technical correction to align the cemetery policy with the existing sex offender registration statute, with no broader changes to cemetery access or policy.

Love Lives On Act of 2025

Maddy summaryThe Love Lives On Act of 2025 modifies veterans' and military survivors' benefit rules to prevent remarriage from automatically ending eligibility. It directly affects surviving spouses of veterans or military members who remarried, ensuring they retain access to key benefits. Key provisions include: (1) preventing termination of veterans' dependency compensation (under 38 U.S.C. §1311/1562) due to remarriage; (2) stopping termination of military Survivor Benefit Plan annuities solely for remarriage, with specific rules for those who remarried before age 55; and (3) expanding TRICARE coverage to include remarried widows/widowers whose subsequent marriage ended (via death, divorce, or annulment). These changes restore or maintain benefits that were previously lost upon remarriage.

Big Oil Windfall Profits Tax Act

Maddy summaryThis bill proposes a new windfall profits tax on crude oil producers and importers, targeting companies that extract or import more than 300,000 barrels of oil per day. The tax rate would be 50% of the amount by which current crude oil prices exceed a baseline set at the 2025 average, with adjustments for inflation in subsequent years. Revenue collected from this tax would be placed in a dedicated fund and then rebated directly to individual taxpayers as a credit against their income taxes. The rebate amount would be calculated quarterly based on the total tax revenue collected and distributed to eligible individuals, with higher amounts for joint filers and income-based phase-outs. The bill applies to oil extracted or imported after December 31, 2025, and includes provisions for territories with mirror tax systems to receive equivalent benefits.
