This is St. Louis Children's Hospital's billing department. They make calls from this number even if there is just a change or adjustment on your bill. NOT A SCAM!

this person just called me looking for my daughter. how they got my number is beyond me. I think it the same as Txgym. They got a bill from the hospital to start collections, but the hospital never sent me or my daughter a bill. (she is a student and the insurance is still under us-her parents)and what is even funnier like others have said...she works for the hospital!

This was a legitimate call from an agency that collects for a hospital where I recently had some test performed. It was NOT a telemarketer.

The calls are coming from MEDICAL DATA SYSTEMS INC, from Vero Beach Florida. As long as these people can pass a background check and have a pulse, they get a job calling you!! You should contact your "actual" local hospital and complain!!!
I know

See this web link. It refers to this phone number specifically several times.

My calls from 866-213-7755 originate out of Gadsden, Alabama, and is a hospital bill collection service. I actually got a live person on line when I answered the third call, he gave me a call-back number which I did call and got the same person, and then looked up that phone number online. We started getting these calls about 2 weeks after receipt of the hospital bill (which has been paid). I called my real hospital who said they do use a service that is supposed to help people set up a payment plan. The collection service could not name my hospital.

Got a call from this number, saying they are with the local hospital, and wanted me to set up a payment plan. I am currently having a payment taken out of my account automatically. Threatened to send me to collections if I didn't set up a payment plan. Told em to GO FOR IT. I work at the hospital, and they will be getting an irate pissed off phone call first thing tomorrow.

It is a billing office for "several hospitals" - an out biller I think they said. I was not happy with getting this call and told them never to call me again. My hospital bill was sent to them to collect, even though I had NEVER gotten a bill from my hospital in the first place, even after calling and asking them to send me one.
