Help! What exactly is Psychotic Disorder NOS?

I'm having a horrible time figuring this out! I'm pretty sure I know, but I wanted to ask.

First, is "Psychotic Disorder NOS" a "disorder" in itself? OR, if you are diagnosed "Psychotic Disorder NOS", does that mean you've got symptoms of a Psychotic Disorder, but not enough to diagnose one, so until you do, there's the "NOS"?

Is that right?

Anyone?

Thanks!
