According to some stuff I read on the internet a HSA will cover hearing protection if you have a letter of medical necessity from a physician. Has anyone ever done this? I am assuming the letter would just say to wear when you are around loud bangs to mitigate worsening hear loss. I am sure someone could think of a more eloquent way to phrase this. Thanks in advance, I always have money left over and it is probably the only way I could justify some molded plugs.
