Oh wait, you're going global, so there's no QueueObj in the
$self->TicketObj->QueueObj->CustomFields() piece.  Hrm...  I actually
have never fiddled with global custom fields.  I don't know quite what
to use there.  I just took a look at the CustomFields_Overlay.pm
perldoc.  It looks like this may work:

my $CustomFieldsObj = RT::CustomFields->new( $session{ 'CurrentUser' } );

while ( my $CustomFieldObj = $CustomFieldsObj->Next() ) {
   next unless $CustomFieldObj->Name = "Provider";
   ....  your SetContent code...

And AddCustomFieldValue isn't right.  What it does is not add a value
to the custom field for your ticket.  It adds a new choice.  So right
now, one of your custom fields is called "Provider" and one it's
possible values (presumably) is "BT" (depending on what type of custom
field Provider is... single, multiple, etc).  So what you're trying to
do is add another choice to the list of possibilities.  So if Provider
had the possible choices of BT, Foo, Bar, or Baz, the user could pick
any of those as a choice for the Provider custom field.  What the
AddCustomFieldValue does is to add another choice to the list of
possibilities.  It does not add a value to the Provider custom field
of the current ticket.
