Last year my husband went to a rehab facility. His insurance didn't cover his stay. They said they would charge $9500 for the stay. The day he went into the facility I started a new job, and my insurance coverage started that day. Because they couldn't get an answer right away from my insurance they made us pay the $9500. They filed a claim for $17,850.00. They said the amt they quoted was a discount for uninsured. They received 70% of the claim and made us pay the difference. Is it common practice to make the patient pay an amount, perform the service, and then filed a claim for more?
