I recently took my sister to the doctor who is hearing impaired. We were able to get an interpreter at this visit which was paid by the state. We also requested the doctor to ask the insurance to pay for the interpreter for future visits. During the visit, while discussing the insurance paying the intrepreter, the interpreter informed the doctor that if the insurance doesn't pay the interpreter for future visits , she would be responsible.When the doctor heard this, she decided she did not want my sister for a patient anymore. As a matter of fact, she also refused to treat her that day. She told my sister she was sorry and then walked out......I am in the process of helping my sister submit a letter of complaint to the ADA....Does anybody have any advice to give my sister on how to proceed with this...We live in the state of Louisiana....
