The ridiculous amount of repetitive texts and emails was anything but professional. To continue asking the same questions, or sending the same information daily just means your automation is more important to you than common sense.

Paid $590.00 co-pay the day of surgery. Later was sent to collections over a $51.00 balance they decided to add on after only 6 weeks. Wow. Really. With medical insurance claims taking months to work through the system? Like a second colonoscopy all over again.

Response from the owner · a day ago

Thank you for your feedback. We apologize for any confusion regarding the billing process but the outstanding balance was from the physician services side, not the endoscopy center. We have forwarded this information to them. Please contact the Practice Administrator directly at 480-985-1700 so they can help resolve this issue for you. Thank you.
