Bad service... also bad communication between ER Billing Department in this Hospital and Central Billing Department in Oklahoma. This is our second time went there, and the second time also they send us bill to pay the service instead of charging our insurance... our part supposed to be just paying $100 for ER visit (based on insurance information in the card).... The nurse from billing dept in ER got our insurance information, but they were not providing the copy of insurance to Central Billing Department in Oklahoma.... 2 days ago, we received a bill from Eden Emergency Medical Group that billed us almost $500 instead just paying $100....This is happening the second time in the second visit.... if we had choice to go to another place that close to us we would.....About service???? two thumbs down.... if I had 4 thumbs that all for of them will be down too....
