I visited Seton's ER in June, recieved wonderful care from their staff and was treated promptly. However, I was not notified that Seton is partnered with US Acute Care. With this partnership, I recieved two astronomical medical bills - one for Seton, one for USAC. Both charged for lab tests. Both charged for IVs. Both charged for staff fees. I am being charged nearly 6x more here for the same treatment that I had to pay for elsewhere.
Overall - great staff, fantastic care, but as I was not notified of this partnership and therefore additional billing, I am beyond disappointed and will not be returning for future care.
