I read somewhere that, as no option was available to eprescribe to the Caremark Hub, one should just send everything to the specialty site in Northbrook, Il. and that they would then send it where it needed to go. I did this successfully until about a month ago when I was sent a fax saying the script I wrote should be forwarded (by fax) to such and such a number. I replied "why should I waste MY time? You forward it!" I did not hear back from them and I continued to send scripts to that address. I now note that the Northbrook option is absent but there is a listing for Caremark Mailorder Electronic, in Scottsdale, AZ. It is just above the fax only option.
