My personal experience with insurance companies is that a lot of the people answering the calls have very little clue about what orthotics are and how they are covered. Once I called to inquire about a scoliosis back brace for my daughter, and after several minutes on hold while they checked my coverage, the representative returned and told me any type of leg brace would be covered. I had a hard time getting her to understand it was a back brace!! How sad is that. Sometimes, also, they don't understand your request because they use different terminology (insurance-speak). Try explaining what you want in a different way.
I am curious though, are you interested in an orthosis for yourself? It seems like if you are looking for one for pain (which is I think the only indication for an adult with scoliosis to wear a brace) it should be covered.
You might try calling back again and ask if you can speak to the department or person that handles durable medical equipment. I finally had to do that to get correct answers for my daughter's brace. You will probably have to be polite yet quite firm.
Finally, if you have a prescription from your doctor for a brace you can have the doctor's office submit it for an estimate of coverage. Many times these insurance companies really can't tell you anything until they have paper in front of them with codes on it.
Good luck, be persistent,
