If you lost the paper referral and know the doctor you were referred to you can either call that doctor's office, or the referral office should be calling you to setup and appointment, depending on what it's for.
I don't know but I would call the ER and ask can the doctor that saw you is able to write out another referral and go pick it up or see if the hospital can fax the referral to the other doctors office so you won't have to actually pick it up. That is what I would request. I hope this helps you.
