I had to do the same, despite recovering from surgery. To make matters worse, after I hit the maximum out of pocket amount the medical centers continued to send bills showing I owed a balance. It took nearly a year and repeated escalation to their executive and legal departments to get them to provide refunds. Calls, faxes and certified letters were completely ignored.

Yup, we always hit our deductible within about 2-3 months due to my kid's therapy, yet we still get full bills from all of our providers even though we should be 90-100% covered at that point. You call the insurance, they say the provider billed it wrong, you call the provider's office and they refuse that they did anything wrong and tell you to call your insurance. It's a never ending cycle.
