Same as above reported by Ginger - 19 Jun 2009. I picked up the phone to answer it and immediately got the message "this is your doctor's office, please call 800-846-5313, and refer to account number ########." Caller ID was MED USA CORP. Ginger's message identifies it as Caller Type: Collection Agency. I tried to push * to replay the message and it immediately went to dial tone. I tried to call the 801 number and it immediately goes to a busy circuit signal - or busy signal. I called the 800-846-5313 and it's answered as "Physicians' Billing Office", and closed for the day. This is harrassment.
