Most OP's require this info. No, they do not contact them. If you can't remember who they are, just open the phone book and pick one. Or you could put the name and # of your clinic, not the Dr., if you still want to be on the up and up.

Your Dr is not allowed to release any info about you anyway without your express consent, thanks to the new Hippa regulations that went in to effect 14 April 2003.
