How is CMS considering changing the laboratory DOS exception mentioned in last week’s question?


The Centers for Medicare & Medicaid Services (CMS) is considering three primary options to modify the laboratory date of service (DOS) exception discussed in last week’s question:

  • “Changing the test results requirement at 42 CFR 414.510(b)(5)(iv);
  • Limiting the laboratory DOS exception at 42 CFR 414.510(b)(5) to ADLTs; and/or
  • Excluding blood banks and blood centers from the laboratory DOS.”

This question was answered in an edition of our Laboratory Compliance Manager. For more hot topics relating to laboratory services, please visit our store or call us at 1.800.252.1578, ext. 2.
