What I am seeing is that the 25 modifier should be on the OV but no modifier on the G0444.
As for the dx, if you are screening for depression then the reason the test is being done is to screen for depression (Z13.31). If depression is determined, and more services follow, then the F41.1 would be appropriate for the services. But the F41.1 wasn't the reason for the G0444, it was the result.
