Looking for a definitive reliable specific resource in relationship to Annual depression screening (G0444) when the depression diagnosis occurs on the same day as a result of the screening service.

I’m finding on forums and AAFP article that once the patient is diagnosed with depression (even at the screening appointment) you can no longer use the screening code. It would become part of the E/M service; however I cannot locate the specific source for this information. Can anyone help me locate the source to support this? We have varying opinions in our office so hoping to find something definitive from a reliable source to clear this up.

Any help is much appreciated.
