Are you reading the 2009 policy or is it a current policy? If you have the old policy, your page 33 is probably different than their page 33. Try to get the current policy so you know what their page 33 says.
I might throw this in. My insurance company lists my BAHA as a PROSTHETIC, not a hearing aid. The abutment, the little screw that gets drilled into your skull, is not an implant...it becomes part of you...it does not come off...your skull grows into screw. The BAHA is a sound processor, not a hearing aid. The key word here is PROSTHETIC. It is not a removable hearing aid. The processor is removable for maintenance and it cannot get wet. The abutment is not removable.
So this is the problem. You have an old policy, they have a new policy. Your page 33 is different than their page 33. You are thinking prosthetic, and they are thinking hearing aid. Ask about their prosthetic policy.
