Per http://twitchy.com/2013/10/03/screwe...ne-number-pic/:

The new national phone number for Obamacare is 1-800-318-2596.
Excluding the 1 digit (since there are no associated letters with 1), that makes the number:
1-800-FUCKYO

I guarantee you this is by design. I remember a few years back there was another acronym the admin used, but I can't for the life of me remember what it was, but the sentiment amounted to the same.
