Four New Tests Added to CLIA Waived List: Effective Date Set for January 1, 2007

On January 1, 2007, Medicare contractors will implement new waived tests approved by the U.S. Food and Drug Administration (FDA) under the Clinical Laboratory Improvement Amendments (CLIA) of 1988. Note that the effective dates for each code, as shown in the table below, vary. Also note that contractors won't search their files to either retract payment or retroactively pay claims but will adjust claims if you bring it to their attention.

As always, the standard rules apply for billing these codes.
