For the third time in two years, Congress has delayed PAMA implementation. The first delay was in a December 2019 budget bill (just before COVID), and the second delay was in one of the spring 2020 COVID acts.
December 2021, Bill #3, the Protecting Medicare and American Farmers from Sequester Cuts Act.
I had a brief blog on this December 8, see more detail at an open access article at 360Dx. It's not just about labs, various sequesters and other cutbacks affected hospitals and physicians in multiple ways.
