Medco is in there - search for Medco - it comes up as fax only. Erx on your end and fax on theirs - this meets requirements for you as ERx but I think you will find Medco, Caremark, etc all want to make it as hard as they can for you to find them so they do not have to pay for Erxs.....I have found many of them, but they list different addresses from the ones on their form or their forms do not list any physical address only a fax - this is so you cannot figure out where to erx them.
