To prohibit the use of Federal funds to implement, administer, or enforce a final rule of the Food and Drug Administration relating to "Medical Devices; Laboratory Developed Tests", and for other purposes.

H.R. 1463 would block the use of any Federal funds to implement, administer, or enforce the Food and Drug Administration’s final rule about Medical Devices; Laboratory Developed Tests (LDTs). The specified rule is the FDA final rule submitted for publication in the Federal Register on May 6, 2024 (89 Fed. Reg. 37286), and the bill also bars funding for any substantially similar rule. In other words, even if the FDA issues or enforces a rule regulating LDTs as medical devices, this bill would prohibit federal dollars from being used to carry out or enforce that rule. The bill was introduced in the House on February 21, 2025, by Rep. Finstad (with Rep. Crenshaw as a co-sponsor) and referred to the Committee on Energy and Commerce. What this means in practice is that the federal government would be barred from funding the actions needed to implement or enforce the FDA’s LDT rule. The bill does not repeal the rule itself; it restricts the use of federal money to put the rule into effect.
