Drug Testing - Any Operational or Policy Changes?

Has anyone modified any of their operational procedures or policies as a result of the new drug coding changes?

They changed from quantitative/qualitative to presumptive/definitive and I'm wondering what else besides superbills or order forms others have changed to accommodate this.

In particular, any practices related to frequency?

Curious to compare notes with other practices. Thanks in advance for any feedback.
