REVENTICS is the worst 3rd party physicians service. My bill was from Emergency Physicians and the number I called go to REVENTICS. I set up a payment plan and missed a month by accident. I continued to make payments and they sent me to collections! When I called them to get it fixed they fought me, told me I did not meet my payment plan agreement and that I needed to talk to collections. When I asked them for a copy of the payment plan agreement (that I had not received) they said one didn’t exist. How can I be in breech of an agreement if one does not exist?!?!? They lack empathy and a quite frankly do not care. Not sure how you can fully avoid them as they are 3rd party. But be prepared for a fight if you encounter them.
