I haven't tried to follow the hint trail in a while. What's the point when nothing happens after so many, "it's time!" posts? Also, I lost the ambition to look any further after finding the implementation timeline. So I guess I will stay tuned.

This likely (hopefully) is the wrong trail, but this is what I have found.

The National Institute of Mental Health (NIMH) doesn’t directly implement insurance coverage for mental health, but there are general guidelines and steps that can help ensure adequate mental health coverage under various insurance plans.
