Cosponsor · Combating Illicit Xylazine Act This bill regulates xylazine under the Controlled Substances Act (CSA). Xylazine, also known as tranq , is a nonopioid sedative and pain reliever that is approved for use in animals. Recently, the Drug Enforcement Administration (DEA) has reported an increase in trafficking of fentanyl mixed with xylazine. This bill adds xylazine, including its salts, isomers, and salts of isomers, to schedule III of the CSA.
Cosponsor · Improving Seniors' Timely Access to Care Act of 2025 This bill establishes several requirements and standards relating to prior authorization processes under Medicare Advantage (MA) plans. Specifically, MA plans must (1) establish an electronic prior authorization program that meets specified standards; (2) annually submit to the CMS for publication specified prior authorization information, including the percentage of requests approved and the average response time; and (3) meet other standards, as set by the Centers for Medicare & Medicaid Services (CMS), relating to the quality and timeliness of prior authorization determinations. The CMS and the Office of the National Coordinator for Health Information Technology must publish on the CMS' website a report that analyzes the information received from MA plans, the feasibility of implementing real-time decision making with respect to prior authorization requests, and the impact of decisions that are made using artificial intelligence on patient access.
