Your HA dispenser is wrong. You do have to medically qualify and in the US that means your speech scores in the standard sentence tests need to below 50% (40% if you are on Medicare). It isn't based so much on where your loss lies, although most people with hearing loss have high frequency loss. I had a ski slope loss with near normal hearing in the low frequencies and no hearing in the high. I was able to hear things like flutes, birds, the timer on my oven, etc. with my CI's that I could never hear with my HA's. Make an appointment with the CI team near you to get accurate information about cochlear implants. They are simply life changing!
